Development of an approach to the selection of the necessary method of arrangement of the left turn in the area of controlled intersection

Abstract

Abstract In this article the analysis of the main ways of the organization of the left turn in a zone of the regulated intersection with use of foreign and domestic scientific sources is carried out. In the analysis the authors determined that today in the choice of the necessary way of organizing the left turn option uses a minimal set of data, namely, intensity of traffic, causing a traffic controlled junctions may not be effective. Studies of changes in the main characteristics of the traffic flow as a result of conflict analysis “left turn-direct conflicting flow” allowed the authors to develop a new approach to the selection of the necessary method of arrangement of the left turn, taking into account changes in the main characteristics of the traffic flow – delay, speed and queue length. The experiment showed the feasibility of using the proposed approach.
