Abstract: To investigate control measurements of crossing pedestrian flows, a field survey was carried out to learn the current conflict situation of Beijing rail transit stations. The conflict process and the characteristics of passenger flow under the conflict were analyzed. Then, optimized measures were presented based on gap acceptance theory and roundabout traffic. To verify the effects of the two measures, a pedestrian experiment was carried out. Validation results show that the gap control measure are capable of decreasing main-minor flows conflict severity, and setting roundabout can decrease the main-main flows conflict severity. As quantification indexes, conflict continuous time, passenger velocity and through efficiency are introduced to analyze the effects of the two measures.
