Research on Dynamic Assignment Problem of Subway Based on High and Low Peak Time Sharing Pricing

Although the subway greatly relieves traffic jams, the phenomenon of congestion within the subway during the peak period continues to increase. From the perspective of traffic demand management, subway time-of-day pricing can relieve peak congestion, shifting part of the passenger flow during the peak period to a low peak period, thereby improving transportation efficiency. In this paper, the dynamic flow allocation model based on timetable is studied. The timeliness of passenger route selection, the influence of congestion on passenger flow, the factors of ticket price and the penalty coefficient of early to late arrival are considered. Through the characteristics of subway operation and the method of high and low peak time-sharing pricing, the subway space-time network is established, and the influence of subway time-sharing ticket price on the passenger flow is discussed emphatically. Finally, an example is given to verify the model and algorithm of this paper.
