Abstract
As an important urban transportation mode, urban rail transit (URT) systems act as a key solution for high-density passengers. For the URT systems, even minor disruptions of can lead to severe harm of passenger safety, large traffic delay and widespread confusion because of the passenger density. In emergency circumstances, quick response and efficient substitution services like bus birding is of great importance for evacuation and accommodation of the affected passengers. In this paper, we propose a mathematical programming with indicator constraints model for designing a responsive bus bridging services under URT line emergency. The response time is integrated as an objective in the problem by considering the distance between the bus parking spots and the URT station as a starting point of a scheduled line. To solve the proposed model, a Genetic Algorithm (GA) based procedure is deployed because of the intractability. The results of some numerical experiments are also provided to demonstrate the proposed model.
