Abstract
In this paper, the problem of setting traffic light cycles at crossroads and intersections is considered in order to reduce traffic congestion by minimizing total vehicle waiting time. In general, a signal light cycle should have the least number of phases. A method to determine the family \(\wp \) of all discrete cycle phasing systems with the minimum number of phases is presented. The aim is to detect from among all the components of \(\wp \) the most appropriate phasing sequence for traffic control corresponding to a current traffic situation, taking into account the activity of all pedestrian crosswalks at the intersection. The method is applied to both a typical and a complex multi-cross intersection. The problem, dealing with traffic movements and the conflicting relations that arise, is stated within the framework of graph theory.
