Abstract
New York City has implemented a suite of interventions to reduce road traffic crashes, including leading pedestrian intervals (LPIs), which give pedestrians a head start over the turning vehicular traffic. This study assessed the effectiveness of LPIs in reducing pedestrian injuries across 6,003 intersections (2,869 with LPI treatment) from 2013 to 2018. They conclude that LPIs are an effective intervention to improve pedestrian safety. City pedestrians must look out for road traffic, especially at busy intersections. This study finds that New York City’s leading pedestrian interval program gives people a head start over turning traffic that improves safety.
