Possible modes and optimization of traffic light operation at a two-lane city intersection

Abstract. One of the urgent problems of optimizing the city’s transport system is the problem of the operating mode of traffic lights at city intersections. The paper presents a solution to the problem of a traffic light operating in a two-phase mode – when one of the lanes is green and the other is red. The presented method is based on the well-known Lighthill–Whitham condition. The consideration of twolane intersections along each of the two lanes is due to the fact that such intersections make up a significant part of the city’s intersection system; the problem can be solved after measuring the main parameters of vehicle movement through the intersection during the period of greatest load.

Keywords: two-lane intersection, optimization of traffic light operation, two-phase mode
