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.

Pedestrian two-stage crossing is an important component of urban road network, and highly affects the network traffic operations
In a two-stage crossing, a refuge island is established at the middle of a crosswalk and pedestrian crossings proceed in two steps

Summary
Pedestrian two-stage crossing is an important component of urban road network, and highly affects the network traffic operations. Studying the characteristics of pedestrian twice crossing behavior at signalized intersections, meets the needs of developing a “people-oriented” urban traffic system and is essential for improving traffic efficiency and pedestrian safety. By allowing pedestrians to wait halfway, refuge islands separate conflicts in time and place. Despite this fact, the proportion of pedestrians involved in red-light violations in the two-stage crossings remain high. Understanding pedestrian’s twice-crossing violation behaviour is an essential issue especially in developing countries with large pedestrian population such as China.
