Abstract
Connected vehicle technologies can track the vehicular level information as well as give the road driver the access to participate in the traffic management. In this paper, we formulate the isolated intersection control problem as a game between the signal controller and the road users in the context of vehicle-to-infrastructure (V2I). The road drivers who can not leave a junction within current cycle are entitled to participate in the game to decide the signal setting for next cycle. In the game, the signal controller maximizes the junction throughput according to the route selections of the participants and estimates the reactions of the participants, while the road users minimize their own cost by choosing their preferred routes with the given signal setting and route selections of other participants, respectively. The results of numerical study on a calibrated network of Caohejing District in Shanghai indicate that our proposed method provides better performances and leads to more even distribution of traffic than the fixed-time control and the throughput-optimal back pressure method, especially at high traffic loads.
