Safety is a top stated priority for nearly every transportation agency. So why don’t we have more comprehensive up-to-date information on the danger of our roads? The limited information we do have fails to explain the scope of our safety crisis, and therefore fails to give us the information we need to address it.
We say safety is our top priority, but we do not have current national data on how many people were killed or injured, or where. The Fatality Analysis Reporting System (FARS) data, the National Highway Traffic Safety Administration’s “yearly” report on deaths suffered in motor vehicle traffic crashes, is wildly out of date and limited. For something constantly described as our highest priority, taxpayers and policymakers are kept woefully in the dark about how bad things are, how we’re trying to address it, and whether or not those interventions are working. We will never improve safety if we don’t measure it better.
T4’s policy proposal for improved safety
In our platform for reauthorization, under our first core principle of “Design for safety over speed” we have a goal to improve the basic data on safety so we can address it. To do this we spell out two things that need to change:
- Publish safety data, such as the Fatality Analysis Reporting System data, to the public within one year of the end of each calendar year, and expand the data to include roadway environment conditions.
- Collect and analyze the deployment of safety countermeasures and results, updating approved countermeasures based on this information.
Three limitations of our safety data
1) There is no national dataset on injuries to people walking or rolling that is reliable, comprehensive, and current.
From the timing to the quality of it, the data we have is wholly insufficient in telling where people are getting killed and why, meaning that we can’t change what and how we build. Currently there is a 16-month lag in FARS data. If you were killed in a car crash in December 2023, it would not be published until the spring of 2025 and the data would lack critical details. The point of FARS is to provide crash data in a timely fashion so that we can address issues with our roads, but it has not served that purpose to this point. Even if this data was updated annually, it would lack critical details including road design and injuries that occurred.
FARS data comes from crash reports that are tracked independently by local police departments and compiled at the state level, all with different recording methods and organizational categories. This leads to an incomplete data set that is released later and later every year. Creating a standardized system around data collection that includes the reasons behind a crash, any injuries, and the environmental conditions could help make reporting more consistent and effective.
2) FARS data does not specifically and accurately report on serious injuries at a national scale.
The second problem with FARS is embedded right in its name and purpose: tracking fatalities. A limited number of emergency departments report injuries. Their race and ethnicity classifications can differ and they are not required to report detailed crash information. Many injuries remain unreported because they are not severe enough to warrant a hospital visit or people don’t have the means or desire to enter into the formal healthcare system. In Dangerous by Design 2024, we estimated that 67,336 people were injured in 2022. But that’s an educated guess, not concrete data. Tens of thousands of people are physically harmed by the way we design our roads, but we have no clue about the true effect. This is a policy failure that seriously hinders our ability to understand the true extent of our safety crisis.
Because this data comes from crash reports, many traffic-related injuries are not recorded if they are not “severe.” Each jurisdiction and report also has their own definition for what constitutes a severe injury, making national reporting more difficult. If someone realizes they were hurt worse than they thought and then go to the hospital later—which often happens to people biking or walking when adrenaline subsides—they are not recorded as a serious injury in a crash report. That injury is then not recorded in FARS. To understand the safety crisis on our roadways, we need to include the missing injury numbers from car crashes in our data. We also need to create guidance and standardize how we track these injuries so that injuries are tracked properly.
3) We lack a full picture of danger on our roadways
FARS fails to capture the kind of comprehensive data we need about environmental conditions, infrastructure, the design of the road or its deficiencies—not just “was a crosswalk present” but also “what was the quality of the lighting.” This means we don’t ever have good information on what is creating our most dangerous roadways.
Crash reports provide limited information about where accidents happen and what the conditions and infrastructure look like. For example, injuries that occur on poorly maintained sidewalks are not recorded at all. All serious non-fatal injuries need to be included in this data. Requiring roadway environmental conditions in crash reports will greatly improve the clarity on what we need to improve. FARS data needs to report more details about crosswalk placement and quality, roadway design speed (not just the speed limit), intersection design, lighting conditions and quality, and roadway user visibility. It also needs to include the state of the roadway repair so that we can understand how roads in poor condition affect safety.
Additionally, FARS makes it impossible to truly assess the impact on different groups of people, especially when it comes to people of different abilities. There is no ability to disaggregate people using walkers, wheelchairs, or other assistive devices from people riding skateboards, bicycles, or rollerskates. FARS data groups people with disabilities under the overarching group of “nonmotorists.” This limits our ability to actively address the fatality epidemic among the disability community, the people who most need our help in creating safe infrastructure. The label nonmotorists includes cyclists and people walking with the disability community, all of whom may have differing needs. Having a specified data set for the disability community would help the U.S. target investments to address the dangers of our roadway design for our most vulnerable communities.
With better understanding of how deaths occur, where injuries are happening, and the infrastructure conditions that are contributing to those deaths, we can better understand the crisis and target money to make changes to improve safety. Having annually updated, improved, and comprehensive crash data is the first step in solving our roadway safety crisis. Only after understanding the true extent of our problem will we be able to target real investments to improve the lives of everyone using our transportation system. We have codified safety as one of the seven national goals of the federal program. Yet we know so little about it. We cannot profess to care about a crisis we are failing to measure well. It’s past time for that to change.
