Planning of replacement services as a response to metro breakdowns

In a public transport network metro disruptions may affect the passenger flow severely. In order to limit this negative impact a well planned while quick response is needed. Some passengers could resort to other already existing lines, including tram and bus lines, if they are operated in close proximity to the disruption. In this case, the frequencies of relevant alternative lines have to be increased. In other cases, however, replacement services with buses have to be established. Both of these responses require the relocation of vehicles. Since typically only few operational vehicles are idle at depots, vehicles and drivers from existing lines have to be moved. This involves the adjustment of the headways of the lines. The objective is to minimize the number of unserved customers, the number of new bus lines, and the travel times of the passengers. A comprehensive mixed integer linear programming model is proposed to construct the new lines and adjust the headways. Moreover, a genetic algorithm is implemented to provide solutions for large networks quickly. Both, the model and the metaheuristic approach are tested on instances based on Vienna's public transport network.
