Traffic Flow Control Method at Intersection by Electronic Token

Abstract

For the advancement of autonomous driving technology, it is expected to establish cooperative field technology between vehicles. Especially smooth traffic control at intersections is one of the important issues for reducing traffic accidents, however a lot of computing resources are required by the previous approach to calculate an appropriate approach timing to intersection based on a large amount of information, such as location and speed of vehicles, exchanged between the control side and the vehicle side. In this paper, we propose the mechanism to control traffic flow in a roundabout manner by exchanging only the electronic tokens with the virtual entry right of each area dividing intersection based on the concept of token block system used in railways for a long time. As a result of simulation, it is confirmed that traffic flow is controlled smoothly by the proposed mechanism.
