Rapid transit network design considering risk aversion

Rapid transit network design is highly dependent on the future system usage. These spatially distributed systems are vulnerable to disruptions: during daily operations different incidents may occur. Despite the unpredictable nature of them, effective mitigation methods from an engineering perspective should be designed. In this paper, we present two new approaches to the rapid transit network design problem. The first one aims at minimizing the impacts of the worst scenario in the network operation. The second one takes into account different risk profiles and also minimizes the impacts of the worst scenario across all the risk profiles.
