The metro system is the backbone of a modern transit system. Nevertheless, no system is fail-proof. In the wake of a major disruption of transit lines, establishing alternative transport means, such as substitute bus (SB) services, are critical for both travelers and operators. In this study, the authors propose a methodology for planning SB services in response to a metro failure that affects consecutive stations in one metro line. Two SB service types, regular SB and flexible SB, are considered to deal with the demand uncertainty arising from passenger balking and reneging. The objective is to optimize the design of SB services with a limited number of available regular SB while considering passenger demands uncertainty. A set of SB routes are generated first, and the optimal fleet size of regular SB for each route is determined subsequently to minimize the expected total cost while satisfying all the scenarios of passenger demands. A case study based on the 9-27 metro accident in Shanghai is used to illustrate the approach.
