Abstract EN
Since crosswalk width and pedestrian green time directly affect the safety of signalized crosswalks, modeling an exact total crossing time model to estimate those two variables is imperative.
The total crossing time needed by a group of pedestrians to cross a signalized crosswalk contains the discharge time and the crossing time.
The discharge time depends primarily on the maximum queue length, which is determined by pedestrian arrival rate, red interval, waiting position distribution, and the crosswalk width.
Crossing time increases when interactions between bidirectional pedestrian flows become more serious.
Thus, quantifying the impacts of the start-up process on the discharge time and the effects of the interactions on the crossing time is a prerequisite for optimizing the design of signalized crosswalks.
This paper establishes a modified total crossing time model consisting of modified pedestrian discharge and crossing time.
Discharge time is modeled by applying traffic wave theory, and crossing time is modeled based on drag force theory.
The proposed models provide guidance for the design of crosswalk width and pedestrian green intervals.
