Simulating Pedestrian Signal Violation at Signalized Intersections with Pedestrian Two-Stage Crossing
Pedestrians are the most vulnerable road users and are at risk of involvement in traffic accidents with severe consequences because of violation behavior. To investigate the mechanism of pedestrians’violation behaviors at signalized intersections with pedestrian two-stage crossing, this paper performs a numerical simulation model of pedestrian crossing behaviors from curbside and refuge considering the impacts of individual demographic characteristics, situational conditions and environmental conditions.The study focuses on different signal control modes and proceeds from characteristic of pedestrians’ violation behaviors, the choice behavior on gap as well as the velocity distribution of pedestrians to construct model. In the simulation model,pedestrians will completely make a decision whether violate the rules and regulations by themselves according to violation module, namely, random forest models. In the end of the paper, validation of the simulation using actual data is explained through the comparison between average violation rates of the existing data with the results of the simulations. And application of contrasting pedestrian violation rates under various traffic flow as well as different control modes is presented.It was revealed that simultaneous control mode could reduce violation rates from curbside, but it leads to higher violation from refuge islands compared with independent one.The microscopic pedestrian simulation can be applied to give more understanding to the behavior of pedestrians’ violation behavior and confirm more suitable control mode on the basic of actual surroundings before its implementation.
