doi:10.16182/j.issn1004731x.joss.201804005

Abstract

Abstract: An improved bi-directional pedestrian model based on reciprocal velocity obstacles (RVO) is proposed to investigate self-organization phenomena for bi-directional pedestrian flows crossing bottlenecks, and the influencing factors of pedestrian flow are analyzed. According to the RVO model problem, an improved method is constructed. The model of bi-directional pedestrian flows crossing bottleneck in subways based on Unity 3D is established. Based on this improved model, the bi-directional pedestrian flows crossing bottleneck in subways is simulated. Simulation results indicate that the model can veritably simulate self-organization phenomena for bi-directional pedestrian flows crossing bottlenecks in subways and pedestrians flow is an increasing linear function of bottleneck width. The present study provides theory evidence for mitigation of bottleneck congestion in subways.

Key words: pedestrian traffic, bi-directional flow, bottleneck, RVO model
