Vehicle Design

debug msg: this block is Large Text Block, Left Aligned

Unsafe vehicle design is exacerbating the safety crisis on American streets. Better design can help solve it.

Research shows the growing size and weight of the vehicles on our roads, along with reduced visibility from the driver’s seat, are directly linked to increased traffic fatalities. But in the U.S., regulations governing vehicle design have not kept pace with this changing reality. In particular, current safety standards and rating systems have failed to protect people outside of cars, especially in multimodal urban environments.

NACTO works to ensure governments recognize vehicle design as a crucial component of street safety in cities, and implement regulations that make our roadways safer for everyone.

Reforming the U.S. New Car Assessment Program

It’s a crisis years in the making: vehicles are getting bigger, leading to a disturbing spike in deaths of people outside cars.

Fatalities and serious injuries among pedestrians and cyclists have skyrocketed by more than 50% in the past decade. But under the federal government’s safety rating system, known as the New Car Assessment Program (NCAP), almost every vehicle gets four- or five-star ratings. That’s because the system only takes into account the safety of those within cars, not outside them.

After NACTO and thousands of concerned residents, safety experts, cities, and organizations called on USDOT in 2022 to reform the program so customers have accurate information on the safety of vehicles that they purchase, the agency proposed the inclusion of an optional pedestrian crashworthiness test within NCAP. While this proposal is a step in the right direction, it still lets automakers off the hook for designing dangerous vehicles.

The proposed pedestrian test isn’t included in the vehicle’s final safety rating, which means vehicles that perform poorly can still receive 5-star overall safety ratings. The test would also be conducted by car manufacturers themselves, and since it’s voluntary, automakers can skip it entirely. And even when automakers do conduct the test, the critical results of it will only be published as a footnote on an obscure website, leaving consumers largely uninformed.

NCAP can be improved in other ways, too: USDOT still needs to incorporate life-saving vehicular features into its ratings, including Advanced Driver Assistance Systems and Direct Vision standards that can prevent bicyclist and pedestrian-involved crashes altogether.

Cities, advocates, and safety experts from across the country have joined our call to update the outdated ratings system that gives misleadingly high safety ratings to the most dangerous vehicles on American roadways. Read what they had to say.

Many cities and transit agencies have also pushed for changes. You can view some of their statements here:

Requiring life-saving technology for new vehicles

NACTO’s member cities and transit agencies are leaders in the road safety movement, utilizing street design changes and speed limit reductions to reduce serious injuries and fatalities. But NACTO members rely on our federal partners to regulate risks that are out of city control, including safety features like Automatic Emergency Braking, Intelligent Speed Assist, and Direct Vision.

In 2023, the National Highway Traffic Safety Administration (NHTSA) issued proposed regulations requiring Automatic Emergency Braking (AEB) for light vehicles like cars, SUVs, and light-duty trucks. This critically-needed standard has the potential to prevent thousands of pedestrian fatalities each year.

NACTO believes NHTSA can make this proposed standard even stronger by including the following additional changes:

  1. Increasing testing speeds for pedestrian AEB systems to mitigate against crashes that happen on higher-speed collector and arterial streets where pedestrians are often forced to interact with vehicles.
  2. Requiring testing in lowlight scenarios on the same timeline as daytime
  3. Retaining the “nocontact criterion” for testing, as well as the specification that would prevent drivers from disabling the AEB system at speeds above 10 km/h.

Taking a public health approach to public safety

Read NACTO’s recommendations (pdf).

The National Highway Transportation Safety Administration (NHTSA) is the part of USDOT charged with motor vehicle safety standards. It has broad authority to regulate the design and technology used in motor vehicles sold in the United States. The agency writes and adopts the Federal Motor Vehicle Safety Standards (FMVSS) and other regulations. It also encourages the collection of crash data through the Model Minimum Uniform Crash Criteria.

Traffic fatalities for vehicle occupants have largely held steady over the last decade, while traffic deaths for people outside of vehicles (pedestrians and bicyclists) have skyrocketed by more than 50% since 2009. Vehicle standards have failed to protect those outside of vehicles, resulting in thousands of preventable deaths each year. Especially in multimodal urban environments, vehicle design and regulation is critical to ensuring safe operations and movement.

NHTSA’s approach to vehicle regulation needs to expand its scope from a limited consumer-protection approach to a holistic public health approach that protects all road users. NHTSA should use its broad authority over vehicle safety and design regulations to support the Biden Administration’s climate, equity, and safety goals by taking the following actions:

  1. Commit to a Safe System approach to all agency activities that puts safety first for all street users.
  2. Update FMVSS to include new, proven safety features to all new motor vehicles beginning as soon as possible.
  3. Expand NCAP star ratings to incorporate the safety of people outside the vehicle and the full environmental performance of vehicles.
  4. Update and enhance funding eligibility requirements for agencies/jurisdictions that receive NHTSA funding for traffic enforcement.
  5. Champion transparent and equitable automated enforcement.
  6. Revise the Model Minimum Uniform Crash Criteria to collect clearer, more actionable data for street and road designers, pursuant to a safe systems approach.
  7. Establish rigorous safety testing standards for autonomous vehicles.

Large vehicle design

Urban trucks and other large vehicles are disproportionately responsible for urban traffic fatalities. In 2018 and 2019, NACTO and the USDOT Volpe Center convened a multi-city working group to identify challenges and opportunities to reduce the dangers posed in urban settings by large trucks, fire trucks, and other large vehicles.

Over the course of the project, partners identified a number of off-the-shelf and/or easily retrofittable technologies, such as automatic emergency braking, and policies, such as Direct Vision Standards, that North American cities could adopt to reduce traffic fatalities and injuries from large vehicles. Because governments purchase a sizable share of the large vehicles that operate in cities, they are uniquely positioned to influence the market for better, safer designs.

In addition, Volpe’s research identified some fire trucks, currently available for sale in Europe, that meet or exceed the capacity of typical fire trucks operating in the U.S., and are smaller, more maneuverable, and more appropriate for urban contexts.

Read our reports on making large vehicles work for cities:

  • Optimizing Large Vehicles for Urban Environments: A joint release with the U.S. Department of Transportation Volpe Center, Optimizing Large Vehicles for Urban Environments is a pair of in-depth reports that detail the effects of vehicle design on street safety, and the opportunities that public agencies have to reduce traffic fatalities with improved vehicle design.
  • Case Studies: Downsized Street Maintenance Vehicles: Case studies exploring downsized street sweeping and snow plow equipment currently in use in Boston, Salt Lake City, Cambridge, MA, and Chicago. They are an addendum to the Optimizing Large Vehicles for Urban Environments reports produced by the U.S. DOT Volpe Center for NACTO in 2018.
