Pedestrian Crosswalk Law: A study of traffic and trajectory factors that affect non-compliance and stopping distance

Figliozzi, Miguel A. / Tipagornwong, Chawalit

Highlights•Pedestrian law compliance is strongly affected by driver trajectory and traffic.•Vehicle origin, traffic lights, and speed-headway changes are novel factors.•Changes in vehicle speed and headways have the highest explanatory power.•Measures to decrease speed increases toward crosswalks may increase compliance.

AbstractWalking is encouraged by many transportation agencies as a sustainable mode that contributes to livable downtowns. Since pedestrians are the most vulnerable road users, safe and comfortable crosswalks are essential to ensure that pedestrian travel becomes an appealing alternative. In this context, the goal of this research is to study the traffic and vehicle trajectory factors that affect crosswalk law compliance and stopping distance from the crosswalk. The results of this research provide new insights into the relationships between traffic conditions, vehicle trajectory, and compliance rates. Results indicate that vehicle origin, vehicle type, stopping at upstream traffic lights, and changes in vehicle speed and headways are key factors to predict pedestrian crosswalk law compliance and stopping behavior; changes in vehicle speed and headways have the highest explanatory power.
