Розробка методу забезпечення пріоритету автобусам на регульованих перехрестях

Abstract

The paper considers new method that ensures bus priority at signal-controlled intersections. The main objective of the study is to substantiate the proposed method a special lane at the and define the principles for its implementation. The method is based on creation of spatial corridor at the area of intersection, using specially allocated lanes, which allow free access of buses to the stop-lines. Intersection passage is realized by means of adaptive control algorithms for traffic light signaling control, particularly through special phase and the principle of split phase control. Six major types of special lanes that are implemented in the area of intersection and depend mainly on the availability and location of stops at the intersection, as well as the change of traffic direction, are proposed. The process of bus passing through special lane in the area of intersection is viewed through the prism of system which allows detailed determining the factors that define its geometrical parameters. The main stage of implementing this method is determining the length of special lane on approach to the intersection and ways of traffic light signaling adaptation for ensuring time priority. The proposed method provides spatial-time bus priority at the intersections (including isolated), approaches of which have no more than two traffic lanes in one direction. Application of this method with more lanes (three or more) is appropriate when introducing the special lanes on the street sections with no breaks at the intersections is inefficient.
