Passenger travel mode analysis method and system under urban rail transit emergency

The invention discloses a passenger travel mode analysis method and system under urban rail transit emergencies. The method comprises the steps that the OD passenger flow floating amount and the OD passenger flow floating rate of an emergency day and a historical same-period normal day in a time period are calculated; determining the time and space influence range of the passenger flow under the emergency; the method comprises the following steps: acquiring urban rail transit basic data, determining explicit variable and latent variable factors influencing passenger travel selection in an emergency, and analyzing the influence of explicit variables and latent variables on passenger travel selection; and the influence of the explicit variable factors and the latent variable factors on passenger travel selection is synthesized, a passenger travel utility function is constructed, and then the probability that the passengers select various travel modes in emergencies is predicted. According to the method, the exp
