The influence mechanism of passenger flow regulation and control measures on commuting person individual behaviors is revealed through big data, and thescale and the regulation and control effect of the controlled group are accurately mastered.

Description

technical field [0001] The invention relates to the technical field of subway passenger flow regulation, in particular to a method for formulating a subway passenger flow regulation plan based on demand evolution and flow propagation. Background technique [0002] With the continuous expansion of the scale of the subway network and the steady increase in passenger traffic, the contradiction between the strong passenger flow demand during peak hours and the limited transportation capacity has become increasingly prominent. During the peak commuting period, when a large number of passengers flow into the local line network in a short period of time, it is easy to cause congestion and paralysis of the station payment area, and the train's full load rate is too high, which is not conducive to the safe and efficient travel of commuters, and also causes commuting at downstream stations. The increase of passenger travel delays, which in turn restricts the passenger transport effici...

Problems solved by technology

[0003] At present, the existing passenger flow regulation planning methods generally believe that the passenger flow demand remains constant during the peak period, that is, assuming that the implementation of the passenger flow regulation plan will not cause changes in passenger flow demand; and too much pursuit of the maximum utilization of train capacity, ignoring passenger delays The problem of service fa
