Urban public transport system vulnerability evaluation method

An urban public transport system vulnerability evaluation method comprises the following steps: (1) firstly, acquiring bus station and route information by utilizing a JavaScript API (Application Program Interface) of a Web end of a bus website, and processing data; 2) modeling a public transport system by using a Space L method, and endowing the nodes with station and line information as attributes; 3) modeling the disaster event according to different characteristics of the disaster event. 4) proposing a new public transport network vulnerability index which represents the change of the network performance. and 5) simulating different disaster events to carry out simulation verification on the public transport network vulnerability, observing and recording the vulnerability index changeof the network model in the simulation process, and obtaining vulnerability evaluation. The vulnerability evaluation method of the urban public transport system provides support for daily maintenanceand management and post-di
