Intersections are challenging locations for all road users, but they can be especially difficult for people walking and biking. Between 2014 and 2016, 27 percent of pedestrians and 38 percent of bicyclists killed in crashes were struck at intersections.

The TRB National Cooperative Highway Research Program's NCHRP Research Report 926: Guidance to Improve Pedestrian and Bicyclist Safety at Intersections provides a succinct process for selecting intersection designs and operational treatments that provide safety benefits for pedestrians and bicyclists, and the most appropriate situation for their application.

In 2016 and 2017, pedestrians and bicyclists made up 18 percent of all fatalities on U.S. streets, despite representing less than 4 percent of all trips. This continues an upward trend in these modes’ share of roadway fatalities since 2007.

An erratum was issued for this report: Tables 15 through 24 have been updated to match the summary Table 25 in the online version of the report.
