Calculation of Affected Passenger Flow for Rail Transit Operation Disruption Based on Timetable

摘要

Quantitative calculation of the affected passenger flow scale under the operation disruption of urban rail transit is of great significance for the formulation of emergency strategies. The different impact of operation disruption on passengers may lead to various affected passenger flow. Based on the timetable, the duration of disruption, and the shortest path time, this paper considers the affected departure time range of origin stations in affected OD (origin-destination) station pairs to calculate the OD matrix of the affected passenger flow with historical data. Various affected passenger flow and the total amount of affected passenger flow can be calculated by the OD matrix of affected passenger flow. The analysis and calculation for the local network of Nanjing Metro proves the feasibility of the proposed method, which can quantify the scale of affected passengers, and is helpful to the emergency management.
