Proposal of autonomous signal control logic using vehicle arrival sensors

Abstract

Nowadays, a lot of people expect the reduction of the cost of the infrastructure, including traffic signals. We discuss and propose the control logic of autonomous traffic signal system, which is one of the answers of the problem regarding the cost. In the proposed logic, the best signal pattern is selected from three points of view, such as safety, smoothness and equality. We can apply the logic to every signalized intersection regardless of the intersection shape and the signal type. The signals based on the logic work sufficiently, but are independent of the central control system.
