Federal Highway AdministrationUS Transportation CollectionThis research aims to find readily observable and measurable field measures and geometric data to evaluate relative crosswalk safety performance. A literature review was conducted and crash data analysis was undertaken to determine the significant predictors for pedestrian crashes at unsignalized marked crosswalks. These factors were used to select nine sites for data collection. Video and radar equipment were used to collect pedestrian and traffic information at each of the sites. Both qualitative and quantitative analyses conducted at each site provided important insights into driver and pedestrian behavior. Ultimately, normalized entering volume (NEV) and no-stop percentage (NSP) are recommended as macro-level surrogate metrics that could be used to analyze pedestrian safety at unsignalized marked crosswalks. They are strongly associated with pedestrian-vehicle conflicts and are based on readily observable and measurable field measures and geometric data.79
