Connecting people to jobs and services week: How bad metrics lead to even worse decisions

When the top priority of our transportation investments is moving cars as fast as possible, the end product is streets that are wildly unsafe—as chronicled in depth last week. This focus on vehicle speed and throughput is the result of outdated metrics that utterly fail to produce a transportation system that connects people to what they need every day. 

A “successful” street, according to the metrics used by most state DOTs and metro areas. But “moving cars fast” as a goal fails to measure whether or not anyone can get where they are going. We need a better standard for success.

For “connecting to jobs and services” week, which focuses on our last of three principles for transportation investment, we’re re-surfacing portions of a post we wrote in 2016 about how one bad metric for evaluating potential transportation investments leads to expensive road projects that fail to get people where they are going every day.

All this week, we’re going to be unpacking our third principle for transportation investment, which is admittedly the most difficult to explain, especially compared to the first two: (1) prioritizing maintenance, and (2) prioritizing safety over speed. Before we can explain “connecting people to jobs and services,” we need to explain how the current federal transportation system is oriented around all the wrong things.

As we chronicled two weeks ago, if there are any existing priorities for the $40+ billion in annual federal transportation investment, it’s that cars should move fast, at all times, on all types of roads, no matter how many people die as a result. But we do almost nothing to measure whether or not any of this federal spending actually helps people get where they need to go each dayOne reason why is this wonky metric—created by the federal government—that nearly every state and local transportation agency uses to evaluate the success or failure of their transportation network.

Bad measures for success lead agencies to make bad decisions

As they plan projects and decide which transportation projects to fund, state and local transportation agencies exhaustively measure something called “vehicle level-of-service” for almost every single investment. Here’s a story to illustrate:

Wanting to rejuvenate their local economy, a local community cooks up plans to redesign the local street running through downtown that was perhaps even short-sightedly widened or converted to one-way travel in the 1960s or 70s. They want to make it safer and create a better environment for doing business—to make it a place to travel to, not through.

But because the street is also a state highway, they soon hear from the state department of transportation (DOT) that their proposed changes will slow down traffic and fail to meet “level-of-service” requirements. As a result, the project will fail to make the cut of the state’s short list of projects. Worse yet, the community is told that in order to make this street safer and “solve” congestion, they actually need to widen it and smooth out any curves, making it a virtual speedway, undercutting their plans to build a place with more enjoyable places to walk and visit—a framework for creating economic prosperity.

This terrific cartoon from Andy Singer shows how this rationale leads us to obliterate all the good things about our streets and places in pursuit of improving level of service:

A guy rototills his garden to eliminate weeds

What is level of service, and how do DOTs come to this conclusion?

Level of service is a system by which road engineers measure how well a road is performing based on the number of cars and the delay that vehicles experience on that roadway. Letters designate each level, from A to F. Just as with our time in school, A is great, and F is terrible.

A, B and C represent free-flowing conditions and F is stop-and-go traffic for vehicles. The score is assessed based on the highest level of congestion on that roadway, even if it only occurs for a few minutes a day. (To be clear, a street that is nearly empty 23.5 hours of the day can get an F if it gets congested during rush hour.) Traditionally, roadway conditions are acceptable if they score a C or higher on non-urban streets and a D or higher on urban streets.

This graphic, created by Jeff Tumlin, the new head of the SFMTA in San Francisco, illustrates how roads can be massively over-engineered to avoid level-of-service “F” with expensive capacity that largely goes wasted during the bulk of the day. Graphic via Strong Towns.

The level-of-service measurement is calculated by first measuring the amount of traffic during the busiest 15 minutes of an evening rush hour. Next, traffic engineers project the amount of traffic on the road in 20 or 30 years to determine if the road has enough capacity to cover the lifespan of the asset. If a road is projected by traffic engineers to lack capacity 20 years in the future—an incredibly fuzzy practice that’s far more art (or more accurately magic) than math—that road still receives a failing LOS grade today, even if the road is adequately suiting capacity needs.

Though there are no formal or federal requirements to do so, most DOTs, metropolitan planning organizations and traffic engineers rely on the level of service (LOS) transportation metric as they plan and design projects, and evaluate which ones will receive funding. I.e., projects that “improve” it get the fast track for funding, and projects that might make it “worse” are shelved or modified.

According to Jason Henderson, professor of geography at San Francisco State University, “Every city I’ve ever come across has some use of [LOS].” Because of the ubiquity of LOS, this largely misunderstood measurement has profound influence on the design of our communities.

This heavy reliance on level of service has dramatically shaped our cities, and it’s why states and metro areas and cities have spent billions to “solve” congestion in a way that has produced dangerous streets, dilapidated downtowns, economic disaster, and long-term maintenance costs that no locality can cover on their own.

Toledo and many other Rust Belt cities have little to no congestion and many of their in-town streets enjoy level of service “A.” Is that a good measure for success?

As Gary Toth from the Project for Public Spaces brilliantly put it in this piece, transportation professionals, “in search of high LOS rankings, have widened streets, added lanes, removed on-street parking, limited crosswalks, and deployed other inappropriate strategies” all because level of service has been the de facto standard over the last 50 years.

Every great street that you can think of in most places you want to visit on vacation probably “fails” level of service.

Congestion and level of service is “bad” because the street is home to numerous places people want or need to visit, the sidewalks are too wide and filled with pedestrians window shopping, there might be bike lanes to allow people to arrive without a car, and it’s almost certainly chock full, not necessarily of vehicles, but of people.

Poor level of service in Annapolis, MD. Tear down those buildings and you could add a couple of lanes in each direction and fix it!

Where did this measure come from?

The 1965 federal Transportation Research Board Highway Capacity Manual introduced this metric and it quickly became accepted as the standard measure of roadway performance. One reason that states adopted level of service so quickly was that it suited our country’s transportation goals in the 1960s of building out a network of interstates and prioritizing automobiles to travel quickly.

But as we explained at length last week, building highways and interstates with speed as the top priority is wildly different from building local and regional streets that create a framework for capturing value and providing for the safe movement of people, whether in a car or not.

Although LOS quickly became the standard, transportation agencies at any level are actually not explicitly required to use it: there are no planning or project design requirements that mandate the use of either LOS or travel modeling. FHWA [in 2016] issued a memo clarifying that level-of-service was never a federal requirement.1 But states persist, partially because the feds have never proposed a better measure of success or a more holistic overarching goal for what our billions are supposed to accomplish.

California was the first to make a notable shift, but more is needed

California set out to change the way they designed their streets and communities by changing the way they measure their performance. In 2013, California legislature passed a law directing the Office of Planning and Research (OPR) to instead measure vehicle-miles traveled (VMT), making it possible for projects aiming to reduce driving to fare well in the evaluation process. In 2013, Governor Jerry Brown signed into law SB 743, eliminating the use of level of service for projects within designated transit priority areas (i.e, areas with decent transit service.)

As Streetsblog LA reported in 2013, because most urban areas fall within the state-defined parameters of a transit priority area, this means that level of service is largely eliminated as a consideration for urban projects. Additionally, SB 743 authorized Governor Brown to develop a new way of measuring traffic impacts of major projects statewide and based the new way on total vehicle miles traveled (VMT) rather than intersection congestion.

Depending on how California implements this, it would change how development and transportation projects are analyzed and scored in traffic impact studies and thus send the state’s billions in transportation dollars toward projects that will help meet the state’s overall goals—rather than projects that will simply keep the cars moving quickly at all costs.

In short, instead of measuring the success of a proposed project by only the limited measure of whether or not traffic might slow for a few minutes per day at rush hour, CalTrans will now measure whether or not a project contributes to other state goals, like reducing greenhouse gas emissions, developing affordable multimodal transportation options for residents, preserving open spaces, or promoting diverse land uses and infill development. It is expected that this change will make it easier to build transit projects, as well as bicycle and pedestrian-friendly infrastructure—instead of encouraging more development that works against California’s own environmental and other goals.

$40+ billion is spent each year with no clear measures for success other than “move cars fast”

We need better priorities for federal transportation investment than just “move cars fast, all the time.” A fundamental principle has to be that the people who use our transportation system should be able to get where they are going. That’s where we are going with our third principle, which we’ll be unpacking in another post: “Connect people to jobs and services.” This metric would be a far better measure of success than anything on the books today, and some places are already starting to implement it.

Safety over speed week: The key to slowing traffic is street design, not speed limits

Today, as “safety over speed” week continues, we’re running a guest post from our friends at Strong Towns that uses some simple pictures to explain how street design is a far more powerful tool for slowing down traffic and prioritizing safety compared to the strategy of lowering speed limits.

It’s “safety over speed” week here at T4America, and we are spending the week unpacking our second of three principles for transportation investment. Read more about those principles and if you’re new to T4America, you can sign up for email here. Follow along on @T4America this week and check back here on the blog for more related content all week long. Today’s post was written by Strong Towns and was originally posted in January of this year. We are thankful to Chuck Marohn and his Strong Towns team for letting us repost it here.

The cost of auto orientation—designing our towns and cities around the easy, fast movement of cars—is not just measured in dollars and cents. The number of U.S. traffic fatalities in 2017 topped 40,000 people. Nearly 6,000 of those people were on foot—a 25-year high. Each of those people had a unique story. Each of them had a family.

And after each high-profile crash, we all hear the same litany of advice from law enforcement and traffic safety professionals.

“Be hyper-aware of your surroundings.”

“Always obey the speed limit.”

“Speed is a factor in 30 percent of crashes.”

“Safety is a shared responsibility.”

And yet, we know that people are sometimes going to make mistakes. Even conscientious drivers make mistakes. People walking, going about their business, are going to make mistakes. No one is going to be hyper-vigilant every moment that they’re out in the world. And why should we have to?

We can’t regulate our way to safety. We must design our streets to be safe.

Two simple photos reveal what it means to design a street to be safe, versus counting on the speed limit alone to do the job. This meme was created by planner Wes Craiglow of Conway, AR, and shared on social media by the “Transportation Psychologist,” our friend, Bryan Jones. We first shared it back in 2015, but it remains timeless, so here it is again:

12189751_793987447390525_7047780377547951323_n.jpg

As Wes points out: “The meme is intended to help viewers consider how different street designs makes you feel as a driver, and ultimately affect how you behave behind the wheel. Generally speaking, as depicted by the lower photo, narrower travel lanes, shorter block lengths, and a tree canopy, all contribute to drivers traveling more slowly. Conversely, wide lanes, long block lengths, and open skies, as seen in the upper photo, communicate to drivers that higher speeds are appropriate.”

Look again at the two photos. Imagine yourself behind the wheel of a car on each street. On which street would you drive faster? On which street would you exercise more caution?

“Forgiving” design is a misnomer

12189751_793987447390525_7047780377547951323_n.jpg

The first photo looks like tens of thousands of suburban streets all over America. It’s entirely representative of something the transportation engineering profession calls “forgiving design.” The premise is simple: drivers will make occasional mistakes—veer a bit out of their lane, fail to brake quite hard enough—and if the street is wide, with high visibility in all directions, and free of immediate obstacles such as trees and fences, those mistakes won’t be catastrophic.

The problem: this street feels too forgiving to a driver. Too safe and comfortable. So drivers speed up. The engineers didn’t account for this aspect of human psychology.

This residential street is built like a four-lane highway, and so even though its legal speed limit is 20 miles per hour, it’s no surprise when somebody guns it up to 40 miles per hour or more down a street like this. It feels natural to do so. It feels safe. But it isn’t safe—because on a city street, unlike a freeway, there might be people around. People who will most likely be badly hurt or killed if a speeding driver hits them.

Read transportation engineer Jon Larsen’s explanation of why the forgiveness of slow speeds is better than the “forgiving” design of wide streets.

The paradox of street design: if it feels a bit dangerous, it’s probably safer

12189751_793987447390525_7047780377547951323_n.jpg

The second photo, on the other hand, represents the most basic, frugal approach to designing a street for slow speeds. It’s not perfect. It lacks sidewalks or bicycle facilities, which some of our readers might take issue with—and yes, many places ought to have those things.

But this “slow street” does something really profound and important. It causes drivers to slow down, whether or not there’s a posted speed limit or law enforcement is present, because of the uncertainty and sense of heightened risk.

The street is narrow. Visibility is limited—look at that front left corner of the intersection, where a red fire hydrant stands next to a white fence. The lack of visibility there is not a safety hazard: paradoxically, it’s probably the single biggest thing that promotes safety at this intersection. Because if you’re driving here, and can’t see whether a vehicle is approaching from the left, what are you going to do?

That’s right. You’re going to slow down.

Read Daniel Herriges’s article on why narrow streets can deliver a ton of benefits to our cities and towns at low cost.

Why 20 miles per hour?

If we could keep most urban traffic to 20 miles per hour or less, we could eliminate the vast majority of deaths from car crashes in our cities and towns. We wouldn’t eliminate mistakes—people, both inside and outside vehicles, are going to make them—but those mistakes would rarely be deadly.

The place for wide lanes and “forgiving design” is on a high-speed road. City streets, on the other hand, should be places for people. We know how to design streets that will slow down traffic automatically, without the need for heavy-handed enforcement, and regardless of what the speed limit sign says. We just need to do it.

Safety over speed week: Prioritizing safety is intrinsically connected with improving transit service

Nearly every bus transit rider starts and ends their trip with a walk, and decisions made to prioritize vehicle speed over safety often have significant impacts on transit. This excerpt from the new book Better Buses, Better Cities helps explain how better bus transit and prioritizing safety over speed are intrinsically related.

It’s “safety over speed” week here at T4America, where we are spending the week unpacking our second of three principles for transportation investment. Read more about those principles and if you’re new to T4America, you can sign up for email here.

The content that follows is an excerpt from “Better Buses, Better Cities: How to Plan, Run, and Win the Fight for Effective Transit” by Steven Higashide, published by Island Press. Steven is a former colleague of ours at T4America as an outreach associate based in New York a few years ago before moving on to the Tri-State Transportation Campaign and then to TransitCenter, where he today serves as the research director. We are proud to see his book in print and are thankful to him and Island Press for letting us share this long excerpt from Chapter 4 entitled MAKE THE BUS WALKABLE AND DIGNIFIED, sourced from pages 59–61 and 74-75. – Stephen Lee Davis, T4America.

On a Saturday afternoon in April 2010, Raquel Nelson, her 4-year-old son A.J., and her two other children (aged 2 and 9 years) stepped off the bus across the street from their apartment in Marietta, Georgia. It had been a good but long day. Raquel and her children had celebrated a birthday with family and pizza. To get home, they took their first bus from the pizza restaurant to a transit center, where they missed their connecting bus and had to wait more than an hour for the next one.

Home was across a five-lane, divided road. And so, together with several other people who had been on the bus, the Nelson family crossed halfway across the street to wait in the median. As Raquel stopped to gauge traffic, one of the other adults in the group decided to start walking. Raquel’s son A.J. broke free from her grip to follow, and Raquel hurried to catch up.

A.J. was killed moments later, by Jerry Guy, who was behind the wheel of a van despite having “three or four beers” in his system.

Raquel and her 2-year-old daughter were also struck and injured. And yet that was only the beginning of her ordeal.2

County prosecutors charged Raquel with vehicular homicide, which carried a potential sentence of 3 years in prison. A jury convicted her, and she was sentenced to 12 months’ probation with the option of a retrial, which she chose. Her case wound through the courts for 2 more years before Raquel agreed to plead guilty to a single charge of jaywalking.

Raquel Nelson’s case made national news. But the loss she and her family experienced is replicated in nearly every city on wide “arterial” roads that encourage high speeds. In the City of Los Angeles, for example, 6 percent of streets are responsible for 65 percent of traffic deaths and injuries. When mapped, pedestrian deaths line up on these roads like dominoes.

Because they tend to have important destinations on them, arterial roads also tend to carry the most bus riders. But the tie between transit and walkability goes beyond pedestrian safety. Nearly all transit riders are pedestrians at some point during their trip. In Los Angeles, for example, 84 percent of bus riders get to their bus stop on foot.

The pedestrian experience is the transit experience, then. A bus rider may appreciate frequent and fast service but still be dissatisfied with her trip if she has to trudge through mud on the way to the bus stop, cross the street with her head on a swivel, and wait in the rain with no shelter. Someone who uses a wheelchair may be unable to use the bus at all if there are no sidewalks leading to the stop.

Poor walkability is corrosive to bus ridership and makes it harder to improve transit service. In Staten Island, New York City, transit planners had to make major adjustments to a redesign of the borough’s express buses after riders complained that the changes forced them to walk in the street or on lawns.

Although Austin’s bus network redesign has generally been considered a success, it ran into the same problems. More than a month after the launch of the redesign, Capital Metro was still moving stop locations in response to complaints that people had to transfer in places without good walking infrastructure. “If you’re going to go to more of a grid-based system and you’re going to have more on-street connections, then you really need to look at the pedestrian experience of those intersections,” Capital Metro’s Todd Hemingson said. (As of April 2019, only about 60 percent of streets in Austin have sidewalks.)

Improving the walk to transit, on the other hand, can have measurable impacts on transit ridership. Ja Young Kim, Keith Bartholomew, and Reid Ewing of the University of Utah found that after the Utah Transit Authority built sidewalk connections to bus stops that lacked them, ridership at those stops grew almost twice as fast as at stops in similar neighborhoods that had not been improved. Demand for paratransit was also stemmed near the stops with sidewalk improvements, saving the agency on its budget.

Although walkability and transit can’t be separated, government usually makes its best effort to do so. Just as transit agencies must convince cities to give transit priority on the street, they must rely on local and state government to create a good walking environment. That’s no given.

The state of walking in America represents an enormous collective failure. Even in urban neighborhoods where many people walk, engineering practices that favor drivers tend to degrade the experience. Intersections can be designed with slip lanes that allow cars to gun through turns. Zoning may allow curb cuts that turn the sidewalk into a gauntlet of traffic. The default rule at most intersections is “right turn on red,” intrinsically hostile to people walking because there’s never a time when they can be sure cars won’t turn into their path.

These decisions are rooted in a philosophy that prioritizes vehicle speeds and is often baked into engineering measures and practices. Engineers often assess streets using a metric called “automobile level of service,” where an A grade is free-flowing traffic. A major traffic engineering manual recommends against striping crosswalks unless at least ninety-three pedestrians already cross the intersection per hour—or if five people were hit by cars at the intersection in the past year. Peter Furth, an engineering professor at Northeastern University, has pointed out that “Synchro, the standard software [traffic engineers] use, is based on minimizing auto delay, and it doesn’t even calculate pedestrian delay.”

Although most streets are municipally maintained, most cities require local property owners to maintain sidewalks abutting their property. This means that wealthier neighborhoods tend to have better maintained and safer sidewalks. The further you get from downtown, the more likely it is that sidewalks themselves will shrink, decay, or vanish. Property owners may not be required to build sidewalks at all, which means many cities simply lack sidewalks in a huge portion of their territory.

Fighting for People on Foot

Pedestrian infrastructure doesn’t cost much relative to other transportation infrastructure. Houston’s $83 million in backlogged sidewalk requests could mostly be wiped out by nixing a $70 million project to add an interchange on an area toll road. Even the $1.4 billion price tag to build functional sidewalk on every Denver street doesn’t look so daunting when the Colorado Department of Transportation is spending $1.2 billion in just 4 years to widen Interstate 70, which runs northeast of downtown Denver.

Shelters aren’t particularly expensive either, costing roughly between $5,500 and $12,000 each. In 2017, medium and large transit agencies spent $297 million on infrastructure at bus stops and stations, compared with $2.2 billion on rail stations—or about 6 cents per bus trip and 47 cents per rail trip.

Creating walkable places requires changing municipal processes so that compact planning (creating neighborhoods where there are many destinations worth walking to) and pedestrian-friendly street design become routine.

This often starts with outside advocacy and political action.

The do-it-yourself movements I mentioned earlier in this chapter ultimately seek not to supplant government but to prod it to action. A year after MARTA Army launched its “adopt-a-stop” campaign, the state of Georgia awarded the Atlanta Regional Commission $3.8 million for bus stop signs, shelters, and sidewalks. Cincinnati’s Better Bus Coalition doesn’t just build benches; it has also published an analysis showing that shelters are disproportionately in wealthy neighborhoods. Streetsblog USA runs an annual “Sorriest Bus Stop in America” contest that has gotten governments in Kansas City, Maryland, and Boston to address bus stop walkability.

In Nashville, a long-time neighborhood activist, Angie Henderson, was elected to the city’s Metropolitan Council on a platform of walkable neighborhoods in 2015. Henderson later sponsored and passed a law requiring most developments in inner-city neighborhoods and near commercial centers to include sidewalks or pay into a citywide sidewalk fund. Denver’s City Council created a $4 million fund to help lower-income homeowners fix the sidewalks in front of their houses and budgeted for three new Public Works employees to manage the program and step up enforcement of sidewalk regulations throughout the city. And Seattle’s Department of Transportation has broken with the engineering guideline that says crosswalks should be striped only where many people already cross or where there are frequent pedestrian crashes.

Within transit agencies themselves, it’s important to raise the profile of the walk and the wait. Metro Transit’s Better Bus Stops Program is a great example. The decision to elevate a routine process into a branded program gave bus stops new stature throughout the agency.

“[The process of siting bus shelters] could be thought of as very dull and unimportant,” Farrington said. “But to package it, to get a great little logo and have it be a substantial program with its own name and people, it’s been a positive spiral of more resources and more support of the work.” She said that staff who had previously worked on park-and-ride stations were now spending more time on bus stops. True, in some ways the program was an outlier, funded by an Obama-era discretionary program, Ladders of Opportunity, that no longer exists. But transit agencies could replicate it using funding from many other sources.

Metro Transit’s program also offers a clear example of how well-resourced, well-planned public engagement can strengthen and educate both the transit agency and the communities it operates in.

Safety over speed week: Drive like your kid business lives here

Economic slowdowns are generally a bad thing. But slowing down might be good for the economy, so long as we’re slowing vehicle speeds. Streets designed to accommodate (slow) drivers, people walking and biking, and transit riders are better for businesses, save money on health care costs, and can help businesses attract and retain talent.

It’s “safety over speed” week here at T4America, and we are spending the week unpacking our second of three principles for transportation investment. Read more about these principles and if you’re new to T4America, you can sign up for email here. Follow along on @T4America this week and check back here for more related content all week long.

Imagine a vibrant commercial corridor, with people window shopping, eating at a sidewalk cafe, or chatting in a plaza. Perhaps there are cars parallel parked under trees planted next to the wide sidewalk. Some are locking up their bikes while others are waiting at a clearly marked bus stop. Cars are traveling slowly and crosswalks are frequent. 

Now imagine that place where the slow traffic is replaced by high-speed vehicles on the nearby roadway. The sidewalks no longer feel like a place to stroll and window shop and outdoor seating is unpleasant—the people have disappeared because it feels unsafe. The sidewalk might be narrowed and trees removed to accommodate more lanes to move more cars quickly past the once vibrant corridor. The people may be gone, but the businesses are still there and struggling to hang on. 

In America today, we are much more likely to build the second lifeless street that prioritizes speed than we are to build the first vibrant street that prioritizes safety.

Our transportation policies are designed primarily to move vehicles as quick as possible while ignoring other users. Instead of sidewalk cafes and cyclists locking their bikes, the street is empty. Instead of parking and shopping, motorists speed through, on their way to somewhere else. Public transit riders have disappeared too, as this is no longer a destination, it is a place to drive-through. 3

Our focus on keeping cars moving above all else harms local economies. Study after study has shown that business sales at worst stay the same but often increase when we redesign streets to lower speeds and safely accommodate people walking and on bikes. Getting more people (i.e potential shoppers) on the street is key.

Streets with slower speeds are more inviting for everyone, including people walking, biking, and taking public transit, creating the crowds which spend and invest in the corridor. Streets with slower speeds enable environments where people will spend time and linger, creating a sense of civic community, a sense of place. Streets like this are the basic building block of creating and capturing long-term value. And most cities and towns, whatever their size, would never survive without having these incredibly financially productive corridors.

Healthy streets are good for business

Beyond these direct economic impacts of safer streets, making it safer for people to walk or bike can improve community health and reduce medical costs, freeing up public and private dollars to be invested in other ways.

A 2010 report from the National Highway Traffic Safety Administration (NHTSA) found that bicycle and pedestrian crashes caused “$16 billion in economic costs and $87 billion in comprehensive costs, accounting for 7 percent of all economic costs, and 10 percent of all societal harm (measured as comprehensive costs).” Imagine all that money, which could otherwise be spent in local communities. 

Making your downtown a safer place to walk is a key component of economic competitiveness in today’s economy. Research indicates that companies of all sizes are increasingly relocating to walkable and transit-accessible downtowns because that’s where talented workers want to be. Amazon’s recent search for a second headquarters—where access to transit was a core requirement—is just one example of this larger trend. We wrote about State Farm’s similar move to consolidate dozens of offices in just a few transit-connected, walkable locations a few years back.

Congress urgently needs to decide whether or not to prioritize safety over speed with the billions in transportation dollars they give to states and metro areas each year, but fortunately, we do not have to choose between safer streets and our economy. We just have to choose safe streets.

Safety over speed week: Slip lanes would never exist if we prioritized safety over speed

A specific design feature on our roadways is the quintessential embodiment of what happens when speed is the #1 priority and safety becomes secondary. Slip lanes, those short turning lanes at intersections that allow vehicles to turn right without slowing down, are incredibly dangerous for people walking. Yet states & cities keep building them. Why?

It’s “safety over speed” week here at T4America, where we are spending the week unpacking our second of three principles for transportation investment. Read more about those principles and if you’re new to T4America, you can sign up for email here.

Any traffic engineer or transportation official would surely tell you that safety, if not the most important consideration, is truly a core priority. But embedded deeply in our federal transportation program is another guiding principle that stands in direct opposition to safety:  “Cars need to always move fast and never slow down.” Whatever the stated priorities are, this hidden prerequisite makes every other goal a nearly impossible task—especially safety. 

Slip lanes on roads and streets are emblematic of what it looks like in practice to sacrifice safety on the altar of speed, where this underlying goal of “keep cars moving fast at all times” runs counter to the goal of “keep everyone safe while moving from A to B”—even if you say that safety is important. If we truly prioritize safety, as T4America is suggesting in our second principle, we would never build a slip lane on a local street again. 4

What are slip lanes and why do they exist?

It’s important to remember that slip lanes were created to solve one specific set of problems: vehicle speed and delay. 

They were borne of the simple realization by traffic engineers that cars turning right—even on a green light—can produce dreaded congestion because slowing down to a safe turning speed can delay traffic traveling straight. So to solve this one problem, they started adding lanes that allow traffic to make right turns without being required to slow or come to a stop, often accompanied with an additional lane on the approach or the exit. Whether you live in a rural, urban or suburban area, this feature isn’t hard to find: they’re a regular feature in most environments that were designed and built with federal money and guidance over the last 50 years. 

Safety was always at best a secondary consideration, though it really wasn’t considered much at all for decades as traffic engineers started adding slip lanes to road projects all over the country.

Slip lanes are dangerous because they prioritize vehicle speed over the safety of everyone who needs to use the road

Slip lanes increase the distance that people have to cover to cross a street, put people into spots that are often the hardest for drivers to see, and encourage drivers not to slow down when approaching an intersection and a crosswalk—the precise moment they should be the most careful. This slip lane I saw in N. Fulton County, Georgia earlier this summer is a pretty typical design. 

Traveling east on N. Hembree Road (with a speed limit of 40 mph!), if a driver is planning to turn right here and sees the green light ahead, all the design cues are directing the driver to blaze through the right turn onto Alpharetta Highway without slowing down. That driver could be hitting maximum speed right as they reach the crosswalk across the slip lane—exactly the spot where engineers have said that a pedestrian should “safely” cross this street.

I saw a woman crossing here and I was astonished to see that in the time that it took her to take just three steps from the middle of the street towards safety, a minivan goes from entirely out of the frame to just 10 feet away from her.

Because slip lanes were borne of the sole focus on avoiding vehicle delay, all efforts to make them “safer” will be limited. Safety is not why they exist. Even the Federal Highway Administration (FHWA) knows they are inherently unsafe—it’s astonishing to read their guidance for making them, in their words, “less problematic”:

Intersections should be designed to accommodate safe pedestrian crossings using tight curb radii, shorter crossing distances, and other tools as described in this document. While right-turn slip lanes are generally a negative facility from the pedestrian perspective due to the emphasis on easy and fast vehicle travel, they can be designed to be less problematic.

How are slip lanes emblematic of safety losing out to the ultimate priority of speed?

Here’s an intersection in Minneapolis with slip lanes on all four sides. These don’t exist primarily to make anyone safe—safety is an add-on consideration to the primary desire to keep cars moving as fast as possible through this intersection. Those crosswalks and pedestrian “islands” that you see aren’t designed to get anyone across this street in the safest way possible, they are a half-hearted attempt to make the best of a road designed explicitly to keep cars moving quickly above all else. 

Making the experience for people walking on a “negative facility…to be less problematic,” is a pretty interesting choice of words to describe a deadly design feature at a time when pedestrian fatalities are hitting numbers not seen since 1990. But we keep building them because moving vehicles quickly and without delay is the outcome we care about above all others.

What prioritizing safety over speed would look like

As we say in our second principle, local and arterial roads must be designed to put safety first. Protecting the safety of all people who use the street must be a priority reflected in the decisions we make about how to fund, design, operate, maintain, and measure the success of our roads. The next surface transportation law must make safety a priority and start to undo the damage wrought by decades of federal design guidelines and billions in federal transportation dollars.

So what would this look like in practice? This small change in Arlington, Virginia is a great example. 

This is a minor collector road that runs largely through a residential neighborhood—not too far from the future home of Amazon’s second HQ. This slip lane made it possible for drivers to whiz into the neighborhood street without so much as a tap on the brakes. Look down the street and what do you see right after cars have sped through the gentle right turn? A crosswalk. That’s what it looked like back in 2009, but here’s what it looks like today:

The lanes were narrowed, the slip lane was eliminated, the right turn was converted into a sharper turn that requires drivers to slow down before turning, and the crosswalk was moved to the safest and shortest point of the intersection where pedestrians will be the most visible. 5

It’s very possible that because cars now have to slow down to turn right, that traffic occasionally slows down on the main road. There could even be a slight back up if a few people are turning right and have to yield to someone crossing the street. But this change is exactly what it looks like in practice to prioritize safety over vehicle speed or delay. 

While this small change is certainly one worth celebrating, this isn’t the standard practice of state DOTs that control the lion’s share of federal transportation funds, and speed remains their number one priority—even if they have a stated commitment to safety. This project was the result of a local county making decisions on their own and with their own funds. Most states will not change their practices unless Congress gives a guiding directive that the lives of the 40,000 people who die as a result of traffic fatalities each year are more important than a few seconds of delay.


Access to safe, convenient transportation is a fundamental right. Today, most Americans are denied this right because their roads—not just their highways—are designed to move vehicles at the highest speeds possible, and roads are not designed for people walking, biking, or taking transit as a priority. Safety may be important, but it’s never the top priority when designing these streets.

Until we come to grips with the fact that moving cars fast at all times of day without delay is a goal that can’t always be squared with our other priorities—especially safety—and until we can admit that perhaps everyone is not going to be able to go fast all the time, we’ll continue building unnecessarily large and expensive roads where thousands of people are killed each year.

No more slip lanes. Because safety should be a primary goal of our transportation investments.

Competition: Which street is the most dangerously-designed?

This week, we’ll be taking a deep dive on our second principle for transportation policy: design for safety over speed. Throughout the week, send photos of streets in your area that are designed for speeds far higher than the posted speed limit or where the speed limit is way too high for the context. On Friday (Nov. 8), you’ll have a chance to vote for the worst offender.

At slow speeds, cars can mix safely with other road users. High-speed interstates remove conflicts to keep people safe. But when people and high-speed traffic mix, that’s a recipe for disaster.

There’s a difference between the speed limit posted on a road and the speed the road has been designed for. People will drive at the speed they feel comfortable, regardless of the speed limit. Wide, straight lanes with open skies, long blocks, and few traffic signals or stop signs tell drivers it’s okay to go fast. Conversely, narrower lanes, more frequent crossings, and street trees can encourage slower speeds that are more appropriate for developed areas.

Off the interstates, in areas with shops & restaurants, offices, schools, and homes, we should be designing for slower speeds—speeds that keep people walking, biking, or taking transit safe and comfortable. Too often these very streets are designed to encourage high-speed thru traffic and then we wonder why our streets are so dangerous to people walking and biking.

Send us photos of dangerous streets in your area! Email us at jenna.fortunati@t4america.org or tweet your photo(s) to @t4america and tell us a little bit about it. On Friday, we’ll poll our followers to identify the most egregious example of a street that prioritizes speed of people’s safety.

Examples of unsafe streets abound, and it’s not just suburban arterials. Take for example, Georgia Ave NW through the heart of Washington, DC. The posted speed limit is 30mph, but this four-lane, two-way road is arrow straight and drivers rarely travel at or below 30.

Within a few hundred yards of this photo there are laundromats and pharmacies, numerous bars and restaurants, homes for thousands of people, an elementary school, and a church. There’s also a metro stop and a dozen different bus stops—people walking are everywhere. Yet the design of this street clearly prioritizes the speed of car traffic over the safety of everyone else.

We want you to send us photos of streets where cars routinely drive above the speed limit (or where the posted speed limit is way too high) because the street isn’t designed to prioritize safety, or not designed appropriately for its busy context. Snap a photo this week and send them to us with a short description via twitter or email. On Friday, we’ll hold a poll on our Twitter account where you can vote for the worst offenders.

Rural areas desperately need a transportation overhaul, too

People disparage rural areas with the term “flyover country,” but our federal transportation program currently treats rural areas even worse—as “driveover” country. If Congress adopts Transportation for America’s three new policy principles, transportation investments could truly help rural areas prosper. 

A focus on speed rather than safety and access would result in telling Erwin, TN that they need to widen this road and get rid of the crosswalks. Federal transportation policy doesn’t work for rural America.

This week, we released our three guiding principles and three outcomes we expect from any new investment in transportation. These ideas will start to fix our broken system and improve safety and access to opportunity for all—including rural areas. 

When I was a small town mayor in Mississippi, I fought transportation policy that treated our town like it was “driveover” or “drive-through” country. Our transportation program makes it far easier for rural communities to build highways—which residents can use to drive far away for jobs, schools, education, and other services—than it does to help rural places invest in their vital town centers. 

What the federal government doesn’t realize about rural areas is that they are not comprised of empty towns and open fields that need to be driven through as fast as possible. In reality, rural areas are dotted with countless walkable town and community centers.

In some rural areas, these walkable places are the center of commerce and activity for that town. But unfortunately, in too many rural areas, thanks to federal transportation policy that prioritizes new highway construction and roads designed primarily for speed—no matter their context—these once-thriving walkable places have been hollowed out, with jobs and services now located far away.

Our three principles would improve life in rural areas by finally treating rural areas as places to be, not places to drive away from. 

Maintenance

When I was mayor of Meridian, Mississippi, the state had 12,000 bridges that were structurally deficient. This hammers rural places especially hard. If a bridge needs to be shut down—or even worse, collapses—some areas might lose their only quick connection, and then people can’t get to their doctors, produce can’t get to market, and students can’t get to the community college. Without these bridges, rural areas are isolated. 

Unfortunately, the current federal transportation law allows states to kick the proverbial maintenance can down the crumbling road. Many times, states use this money to build new infrastructure while letting their existing assets crumble. (Something Mississippi did for many years, though their state DOT has recently made a drastic about-face, a story Mississippi DOT Commissioner Dick Hall outlined in our press briefing for Repair Priorities.)

That’s why our third principle, “prioritize maintenance,” would require states to fix these structurally deficient bridges before building new roads or bridges they can’t afford to maintain. It would ensure that rural places will not be stranded. 

Speed

Oftentimes, the main street of a rural community is a state highway that passes right through the heart of downtown. Because of federal design standards and a focus on the speed of travel above all other priorities, the main street is unsafe and unattractive for people to bike and walk in a very small urban grid, and it’s terrible for the local economy. 

Main streets shouldn’t be highways that get people through communities. They should be arteries that bring people in. Walkable main streets in rural areas can and should be a huge driver of economic development for a small town, generating a large, prosperous tax base in a very small area. 

In West Jefferson, NC, by prioritizing safety and access over speed, 10 new businesses opened along Jefferson Avenue—adding 55 new jobs— and the number of visitors to downtown increased by 14 percent. Four-way stop signs, crosswalks, and upgraded sidewalks were added—anathema to our broken system where speed is the top priority.

That’s why our second principle, “design for safety over speed,” would prioritize designing main streets to serve their intended functions, not as unsafe highways for speeding traffic right through a town center. Any road embedded in an urban grid where people walk and bike, where businesses or homes are located, and where an outside portion of the county’s economic base is located—like in countless rural downtowns—should never be designed for deadly highway speeds. 

Access

When state DOTs build new transportation infrastructure, they might share how wide the shoulders are going to be or brag about how much a new road will speed traffic up, but they never tell the public how transportation projects will make their lives better. That’s because improving people’s access to destinations is not how we measure success. We “measure” success by how fast vehicles are traveling, with no measurement of what destinations you can actually reach. 

Bentonville, AR’s downtown is a place to bring people to and connect to nearby neighborhoods, not to speed cars through on their way somewhere else.

Put another way, traveling for 15 minutes at 40 mph and going 10 miles is preferred to traveling for 15 minutes at 20 mph and only going five miles, for absolutely no good reason at all. If every daily need in a small town is a 15-minute drive at 20 mph, what’s the point of building a brand new road on the edge of town that can speed you along at 40 or 50 mph?

This focus on speed results in orienting every transportation project—whether in a big city or a small town—around the goal of moving cars as fast as possible, telling everyone who wants to live in vibrant small towns that the needs of their automobiles come first.

Rural areas also have higher percentages of elderly, low income, and disabled people, presenting greater challenges to connectivity and transportation infrastructure. But when access is truly prioritized—meaning that transportation projects are chosen by how they improve people’s lives by improving their access to daily destinations, no matter how they travel—everybody benefits. 

That’s why our third principle is “connect people to jobs and services.” Improving access means that instead of making a road wider for cars to drive just a little bit faster, a jurisdiction might instead build a crosswalk in a rural downtown, or add a new road to the street grid, because those investments would do far more to better connect more people to more destinations.

The goal of connecting people to the things they need—which is fundamental to the purpose of transportation—is currently missing from the federal transportation program, and this affects rural areas just like it does any big coastal city 

By making access the goal, designing local streets for safer, slower speeds, and ensuring that maintenance is more than just talking point politicians use to get more money to spend, we can improve the lives of people all across the country. 

America’s rural areas are filled with wonderful small towns and vibrant communities. It’s time for our federal transportation policy to build them up rather than pave them over.

Explaining our three principles for transportation investment

Today, T4America is releasing a new set of three concrete, measurable principles for transportation investment.

Last week we explained why T4America is no longer advocating for more money for the federal transportation program and why we need a clear set of explicit goals for the federal program. Today, we’re rolling out our new principles, which are clear, simple, and measurable. You’ll find them incorporated into the “platform” section of our website and we’ll be using them to evaluate every single proposal in the months and years ahead: whether a standalone infrastructure plan or the forthcoming proposals for reauthorizing the nation’s surface transportation law that expires in 2020. 

It’s time to stop spending billions with an unclear purpose for diminishing, marginal returns. We believe these three goals will help finally move us in the right direction.

#1 Prioritize maintenance

The process is inevitable as it is predictable every time the process of transportation reauthorization comes up. We’re stuck in a groundhog day with an infinite loop. Here’s how it goes:

Every interest group, every legislator, every witness before a congressional committee talks about the need to  “repair our crumbling roads and bridges.” On cue, congressional leaders call for more money for the federal transportation program.  And then no one makes any changes to policy to guarantee that this increased funding will actually be prioritized toward reaching a state of good repair. In fact, as we found in Repair Priorities, Congress has gone aggressively in the opposite direction by allowing states to do whatever they wish with the increase in funding. Many times, states use this money to build new infrastructure while letting their existing assets crumble.  And then the same actors are back before Congress, talking about the need for more money to repair their “crumbling” infrastructure. Rinse and repeat.

Our first principle is not about creating some new federal program to achieve a  state of good repair. And it’s not about how much money is needed to repair our infrastructure, either. Our principle is simply a commitment to the American people that the maintenance backlog is cut in half. This would be a sea change. 

Congress can organize the program in any number of ways to cut the backlog in half. And if cutting the backlog in half over six years is the wrong target, let Congress tell us what the right target should be. But tell us exactly where we will be in addressing state of repair after this bill expires, not how much money will be spent. Until then, we believe half is right and we expect Congress to finally tie the program to their rhetoric. 

#2 Design for safety over speed

When we talk about safety, we typically talk about reducing drunk driving, wearing seat belts, and wearing helmets on motorcycles. In recent years, thanks to leadership from former US DOT Secretary Ray LaHood, distracted driving was brought up to equal importance as these areas. 

Yet what has been largely ignored is the role of speed itself in making our roadways completely unsafe for everyone outside of a motor vehicle. Speed isn’t always necessarily deadly. The way to make a high speed roadway safe is by separating opposing traffic; removing conflict points, like driveways and cross streets, and separating or removing cyclists and pedestrians. That’s called a limited-access highway. But we’ve tried to design for similar speeds on our arterial roadways in existing communities while retaining all the points of conflict that make those speeds deadly. 

Between 2008 and 2017, drivers struck and killed 49,340 people who were walking on streets all across the United States, reaching levels in 2017 not seen since 1990. When crashes occur at higher speeds, they are more likely to be fatal, especially when they involve a person biking or walking. Our sister organization, the National Complete Streets Coalition, found in their report Dangerous by Design that most cyclist and pedestrian crashes occur on these arterial roadways in our urban and suburban areas—roads designed for high speed but without removing conflicts. If we want these roads to be safe, they either need to become limited-access highways (unlikely, expensive and damaging for the local context) or they need to be designed for lower speeds with lower speed limits.

We have to take this seriously. The NTSB issued a landmark study in 2017 about how speed is the #1 culprit in traffic fatalities, and that scores of crashes would not have been fatal at lower speeds. Currently we only track whether someone was driving over the speed limit. We don’t track whether the speed limit was inappropriately high. In fact, numerous local governments across the country are in arguments with states on who has the authority to lower speed limits. It’s time to determine and report when speed was a cause of a crash. It’s time to give local governments the authority to lower speeds to make a street appropriate for its surroundings. And engineers should design roadways in support of slower, safer speeds. 

#3 Connect people to jobs and services by prioritizing accessibility

Fundamental to our transportation system (and the hundreds of billions of dollars we invest in it) is that it should provide people with access to jobs and services. This access is essential to an efficient economy, to ensuring that people can make a living and provide for their families, and to providing employers with reliable access to talent. 

Our current federal transportation program uses a poor proxy for measuring access to jobs and services. Transportation agencies measure the speed of vehicle movement along observed portions of roadways and assume that if those vehicles can move quickly, then all trips must be smooth and short. That kind of measurement has resulted in a system that values  a 40-minute commute to work in free-flowing traffic over a 20-minute commute in some congestion.

As it turns out, to make vehicles move quickly means building limited access roadways or widening roads and spreading out all destinations, making trips longer and biking or walking dangerous. So even though vehicles are traveling at high speed, people may not reach their destinations any faster because everything is more spread out. This is particularly true of pedestrians and cyclists, who once may have had to travel across short blocks, now have to cross long distances designed for cars, thanks to the limited-access changes that cut off local streets and eliminate shorter trips.

The technology has finally caught up.  We can now understand, quickly and affordably, how well the transportation system connects people to the things they need. Thanks to aggregated GPS data, we can know where homes and likely destinations are located. We also have congestion data and real-time transit arrival information. With this data, we can accurately calculate how easily people can access the things that they need and how various proposed transportation investments would improve or worsen it.

Some states, particularly Virginia and Hawaii, have already started scoring potential projects under consideration for funding based on the extent to which they improve access to jobs and services. Massachusetts and Utah are investigating doing the same. Congress should follow their lead.

As Congress considers the next surface transportation policy bill, they should ensure that these destination access data are available nationwide. Congress should also update performance measures to replace 1950s proxy measures like speed of travel with accurate, updated 21st century measures. People don’t talk about the average speed of a trip: they talk about how long it took. We should evaluate transportation projects and the overall system the same way.  

By the end of this next reauthorization cycle, the federal transportation program should be reoriented from a program focused on the fluidity of vehicle movement to one that prioritizes and measures access to jobs and services.
