Abstract. Public transit systems in urban areas usually require large
state subsidies, primarily due to high fare evasion rates. In this paper,
we study new models for optimizing fare inspection strategies in transit networks based on bilevel programming. In the first level, the leader
(the network operator) determines probabilities for inspecting passengers at different locations, while in the second level, the followers (the
fare-evading passengers) respond by optimizing their routes given the inspection probabilities and travel times. To model the followers’ behavior
we study both a non-adaptive variant, in which passengers select a path
a priori and continue alo
