Analysis of Route Choice for Pedestrian TwoStage Crossing at a Signalized Intersection

Studying pedestrians’ twicecrossing behavior is of great significance to enhance safety and efficiency for pedestrians at signalized intersections. However, limited attention has been paid to analyze and model pedestrians’ behavior patterns of twice crossing. The purpose of this paper is to determine pedestrians route choices for twice crossing at a signalized intersection, focusing on the waiting position (to cross the street) and walking route. A goaloriented and timedriven model was proposed to analyze pedestrians’ twicecrossing behavior at signalized intersections, where the two directions have different pedestrian signal timing. A videorecording method was used to collect field data in order to obtain pedestrian preferences in choosing a walking route. It was found that pedestrians in the two directions present different preferences toward walking route, in waiting position, directional change and route type. The results showed that the proposed model is effective in simulating pedestrian routechoice behavior of twice crossing. This research provides a theoretical basis for identifying pedestrian movement intention, optimizing signal timing, and improving pedestrian infrastructure at signalized intersections.
