Abstract:

We compared the difference of waiting endurance time distribution and its influential factors for pedestrians and bicyclists with survivor analysis methods to explore the distinction between crossing behavior of pedestrians and bicyclists at signal intersections. We obtained 1595 behavior data of pedestrians and bicyclists by coding videos at Beijing seven typical signal intersections. We further employed product limit method and Cox proportional hazard model to compare the difference of waiting endurance time distribution and that of influential factors of waiting behavior of pedestrians and bicyclists. Results indicate that no significant difference exists in their waiting time distributions. However, some significant differences exist in the influential factors of their waiting endurance behavior and influential extent. Bicyclists are more sensitive to waiting positions and traffic law violator numbers upon their arrival, while pedestrians are more sensitive to waiting people numbers and vehicle volume upon their arrival.
