A METHOD FOR DETERMINING THE DIMENSION OF APPROACHES AT SIGNALIZED INTERSECTIONS IN URBAN AREAS OF VIETNAM

Abstract

Based on optimization problems for determining the reasonable dimension of an approach, and the results of researches by domestic and foreign authors, this paper suggests a method for calculating the dimension of the approach in two-phase signalized intersections in Vietnam’s urban areas, and at the same time proposes design solutions using the geometric surfaces of these intersections in a logical manner. This lays the foundation for the development of the program \"optimization of the approach dimension in two-phase signalized intersections\" written in Visual C# language on the Windows background to help the designer choose the reasonable approach dimension in the process of carrying out improvements, expansions and building new constructions, thereby contributing to the facilitation of traffic flow capacity and the reduction of congestion.
