The end of daylight savings time means shorter days. Darkness changes how people experience the transportation system. Drivers have less time to detect and react, pedestrians may have fewer safe crossing options, and roadway design can make a dangerous situation worse. In 2023, an estimated 7,318 pedestrians died in traffic crashes in the United States. About 75 percent of those occurred at night.
Help make your roads safer after dark. Find countermeasures for roadways and vehicles in TRB's National Cooperative Highway Research Program NCHRP Research Report 1157: Strategies to Improve Pedestrian Safety at Night: A Guide. The research in the guide was informed by national pedestrian fatality data, case–control analyses of severe pedestrian crashes along higher-risk roadways, driver simulations, pedestrian and driver focus groups, practitioner interviews, and more to create a fuller picture of how the factors interact with one another.

Maintaining, repairing, and modernizing the nation’s aging dams and other water resources infrastructure can be complex and costly. Innovative materials—and the processes used to manufacture and deploy them—can shorten construction and repair periods, but broader adoption requires coordinated efforts to promote and incentivize their use. Strategies include prioritizing adoption, demonstrating and monitoring performance, and providing personnel with training and resources.
In TR News, TRB’s Dylan Rebstock highlights findings and recommendations from the National Academies consensus study report Innovative Materials in Water Resources Infrastructure: Opportunities for the Corps of Engineers.
