Abstract

Studying pedestrians’ twice-crossing behavior is of great significance to enhance safety and efficiency for pedestrians at signalized intersections. However, researchers have paid little attention to analyze and model pedestrians’ red-light running behavior on a two-stage crossing at signalized intersections. This paper focuses on analyzing the characteristics of pedestrian red-light violation behavior at the two stages, including the time distribution of violation behavior, the consistency of violation behavior, and the violation behavior in group.  A goal-oriented and time-driven red-light violation behavior model was proposed for pedestrian two-stage crossing. A video-recording method was used to collect field data, and the results show that pedestrians in the two directions present different red-light violation behaviors in time selection and violation count, as well as, pedestrians in the two stages of a direction present different red-light violation behaviors in time selection. The main reasons leading to the phenomena were analyzed, regarding from people’s cognitive psychology and visual perception. The results also show that the proposed model is effective in simulating pedestrian red-light violation behavior of twice crossing. This research provides a theoretical basis for optimizing signal timing, improving pedestrian safety and developing user-friendly transportation system.

Abstract

Pedestrian walking speed is an important and essential parameter for designing traffic signals at signalized intersections. However, there is a lack of understanding of pedestrian speed characteristics in a twice crossing. This paper focuses on analyzing the differences of pedestrians’ crossing speeds between the two stages, and identifying the major factors affecting the speed changes. Pedestrians were classified by age, gender and group size, and pedestrians’ speed characteristics of each group were analyzed. Besides, each age group were divided into five categories by gender and group size, and the effect sizes of gender and group size on speed-changing at the two stages were examined. The results show significant differences in walking speed on different gender and age groups, as well as on different group size. The young group has different factors affecting the speed change in the two directions, and the middle-aged and old groups have same factors affecting the speed change in the two directions. This study proposed a goal–oriented and time-driven behavior model for pedestrian two-stage crossing at signalized intersections, where the two directions have different pedestrian signal timing. The results also show that the proposed model is effective in simulating pedestrian speed characteristics of twice crossing. This research provides a theoretical basis for identifying pedestrian movement intention, optimizing signal timing, and improving pedestrian infrastructure at signalized intersections.
