Effects of High-Visibility Enforcement on Driver Compliance with Pedestrian Yield Right-of-Way Laws

Abstract

This study examined the effects of a 1-year high-visibility pedestrian right-of-way enforcement program on yielding to pedestrians at uncontrolled crosswalks, some of which received enforcement and some of which did not. The program included four 2-week enforcement waves supported by education and engineering components that increased the visibility of enforcement. The study produced five results: (a) enforcement led to a slow and steady increase in the percentage of drivers yielding the right-of-way to pedestrians over the year; (b) the program produced a large change in yielding over the course of the year; (c) the program produced higher levels of yielding to natural pedestrian crossing than to staged crossings, and the changes in both were highly correlated; (d) the effects of the program generalized to crosswalks that were not targeted for pedestrian right-of-way enforcement; and (e) the amount of generalization to unenforced sites was inversely proportional to the distance from sites that received enforcement.
