| Walking is one of the most common modes of daily travel in urban areas. However, pedestrians are the most vulnerable travelers because they are physically unprotected. Therefore, they suffer the most severe levels of trauma when they involve in traffic accidents. Securing pedestrian safety in crosswalks is one of the most important goals for improving the travel safety. In this study, a time separation control method was proposed to upgrade pedestrian safety on crosswalks. Time Separation Control is a signal timing control phase plan that eliminates the existing conflict points between pedestrians and turning vehicles at intersections to secure the crossing pedestrian safety. To evaluate the effectiveness of the Time Separation Control, three types of single intersection---one-way/one-way crossing; one-way/two-way crossing; two-way/two-way crossing intersections---and three existing traffic networks in New York City were used. All of the intersections and network areas were tested in the VISSIM environment, and vehicle delay, pedestrian delay, pure time-space, number of conflict points per cycle, exposed pedestrians and vehicles to the potential traffic accident were presented to evaluate Time Separation Control phase plan. |
