Intersection Traffic Control_(ITC) has attracted extensive attention with the increase of traffic accidents and congestion that has caused huge social and economic losses. The system currently being studied on ITC needs a lot of computations and is based on ans ICU_(Intersection Control Unit) that is neither flexible nor cost efficient. This paper proposes a token-based group mutual algorithm for ITC for autonomous vehicles. To pass the intersection_(IC) safely without an ICU or traffic lights, there should be perfect coordination among autonomous vehicles based on real-time V2V communications. We use two kinds of tokens: a primary token as a privilege and a sub-token as an auxiliary means to increase the performance of vehicle flow. The rational circulation of tokens is the core subject in this algorithm. VTokenIC decreases message complexity and shows better performance in system throughput than existing traffic signal system.
