Problems of Synthesis of Urban Highways Intersections and Methods for Their Solution

Abstract

Two interrelated aspects of the synthesis problem for regulated intersections of urban highways are considered. First, the question of determination of all possible distributions of the allowed intersection crossing trajectories between phases of the traffic light cycle (in other words, traffic separation schemes) is being resolved. An algorithm for solving this problem is described and illustrated. As a result, all feasible traffic separation schemes are being found, with a limit on the number of conflict points of merging tracks if needed. Secondly, the question of choosing the duration of phases for a specific traffic separation scheme is considered depending on the intensity of the incoming flows and their distributions among the permitted directions of intersection crossing. Methods are proposed for taking into account the transport demand and security requirements and a compromise between them.
