Considerations on traffic management in isolated intersections

Abstract

Abstract The continuous growth in the number of motor vehicles in major cities, combined with a stagnant development of road infrastructure, has caused traffic congestion and a range of negative direct and indirect effects. Even if measures were proposed to improve the road infrastructure, such as increasing connectivity or the size of the roads, the benefits would only be temporary, as it is well known that any infrastructure improvement will attract new traffic. The aim of this study is to identify traffic management measures at conflict points in road infrastructure that can improve traffic flow parameters. The study categorizes conflict points as either saturated or unsaturated intersections in order to determine a precise mathematical model for the timing of traffic light cycles that is suitable for local traffic conditions. The theoretical assertions are supported by a case study and conclusions and recommendations are formulated for use in the practice of traffic lights at isolated intersections.
