Summary

This study, conducted by the Federal Highway Administration, investigates the safety effectiveness of crosswalk markings at unsignalized intersections. The primary research question was to determine how the installation of crosswalk markings influences driver and pedestrian behavior, specifically regarding vehicle speeds, driver yielding rates, pedestrian crossing locations, and pedestrian vigilance. The study aimed to provide evidence-based guidance for transportation engineers and safety professionals seeking to improve pedestrian mobility and safety. The research employed a before/after experimental design across 11 locations in four U.S. cities: Sacramento, California; Richmond, Virginia; Buffalo, New York; and Stillwater, Minnesota. Data collection occurred between 1996 and 1997. The sites were selected for their straight, level roadways and excellent sight distances. Most sites were previously unmarked, with markings installed prior to the "after" phase. The study utilized four distinct observational methods: a Pedestrian Entry/Magnet study to track crossing locations; a Right of Way study to record driver yielding and pedestrian aggression; a Driver Speeds/Staged Pedestrian study using laser or radar to measure vehicle speeds under baseline conditions and when a staged pedestrian was present; and a Pedestrian Profile study to assess pedestrian looking behavior and gait. The results indicated that drivers approached pedestrians in marked crosswalks at somewhat slower speeds compared to unmarked conditions. Crosswalk usage increased significantly after markings were installed, suggesting that markings effectively channel pedestrian traffic. However, the study found no evidence that pedestrians became less vigilant or displayed reduced caution when crossing in marked areas. Additionally, there were no statistically significant changes in driver yielding rates or pedestrian assertiveness. Vehicle volumes remained largely consistent between the before and after periods, with one minor exception in Sacramento that was deemed insufficient to impact behavioral outcomes. The authors conclude that marking pedestrian crosswalks at relatively low-speed, low-volume, unsignalized intersections is a desirable practice. The findings suggest that crosswalk markings improve pedestrian safety by encouraging drivers to slow down and by concentrating pedestrian crossings into predictable locations, without inducing complacency among pedestrians. This research supports the use of crosswalk markings as a viable countermeasure for enhancing pedestrian safety in urban and suburban environments.

Key finding

Drivers approached pedestrians in crosswalks somewhat slower and crosswalk usage increased after markings were installed, with no evidence that pedestrians became less vigilant.
