A Game-Based Adaptive Traffic Signal Control Policy Using the Vehicle to Infrastructure (V2I)

Abstract

In this paper, we propose a game-based policy for the signal control of an isolated intersection together with the rerouting of the vehicles in this intersection using V2I technology. The game starts at the beginning of each signal cycle on the condition that there are vehicles delayed in the intersection at the end of current cycle. Then the delayed vehicles negotiate with the signal controller to decide the signal setting for next cycle while rerouting their next movements. During the game, each delayed vehicle selects one route from their own acceptable route space to reduce the intersection delay time, while the signal controller adjusts the signal setting to meet the traffic demand of the delayed vehicles as well as maximize the throughput. The game can be terminated with end conditions in finite rounds. The vehicles coming after the end of game reroute in a similar way with the delayed vehicles but based on the game results. Numerical experiments on a calibrated network of Caohejing District in Shanghai indicate that our proposed method can effectively mitigate road congestions and improve the network capacity, especially at high traffic loads.
