Evaluate The Impact Of Disruptions On New York City Subway System

Jia, Zhengzhe

This research aims to evaluate the impact of disruptions on the New York City subway system to passengers in terms of time and financial loss. A network model will be built to represent the New York City subway system, and the passenger flow will be simulated using the shortest-path algorithm. This paper uses the network and the algorithm to check the delay caused by the removal of one or two subway stations, which represents the disruptions on the subway system. Specially, the disruption events that happen simultaneously are checked to determine whether and to what extent is greater than it when separate events happen. Delays will be calculated for each scenario, and an economic analysis will be performed to evaluate the financial loss caused to the community and the whole society. The research can be useful for evaluating the loss caused by the disruptions that happen in New York City, and contributing to the schedule change decision-making processes.
