• Abstract:
  Transportation corridors are complex systems. Tradeoffs, particularly in terms of traffic mobility, transit performance, accessibility and pedestrian ; interactions, are not well understood. When the focus is on motorized vehicle mobility and throughput, high traffic or vehicle speeds are desirable ; because at high speeds more vehicles can flow per unit of time and roadway section. However, high traffic/vehicles speeds are not desirable for ; pedestrians who have to cross urban arterials. In particular, pedestrians can be highly vulnerable at unsignalized, marked crosswalks where ; pedestrians have the right of way but where drivers’ yield rates are significantly lower than at signalized intersections. Pedestrians are the most ; vulnerable road users, and safe and comfortable crosswalks are essential to ensure that pedestrian travel becomes an appealing alternative. ; Since pedestrians are particularly vulnerable when drivers do not yield at crosswalks, the focus of this research is to understand the factors that are ; associated with low yield rates or crosswalk law non-compliance. In this context, the goal of this research is to study the traffic speed 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.
