Abstract: According to the passenger flow statistics of Chongqing rail transit over the years, the distribution characters of rail transit passenger flow in network operation are analyzed. It shows that the passenger flow distribution is greatly influenced by residents travel behaviors, and stations with large passenger flow are basically located close to two intersections. The different types of station have different passenger flow features, passenger distributions at commercial type station, external hub station and university type station are comparatively average, other stations show obvious rush hour features. Since the largest passenger flow section appears in the upstream of transfer stations, it is necessary to make a good plan in passenger flow organization so as to improve the carrying capacity of station equipment.
