Methods for Designing Signalized Double-Intersections with Mixed Traffic in Vietnam

In the current Vietnamese urban, there are existences of two close at-grade intersections, which are defined as double-intersections. Traffic congestion at these intersections occurs frequently, especially in rush hours. The most considered concern is the short distance between two junctions, which makes the confliction to the mixed flow in this space. This paper presents two methods for designing signalized double-intersections and their application for a case study of Lang - Lang Ha - Le Van Luong - Nguyen Ngoc Vu double-intersections. Based on acceptable results, the methods can be potentially implemented for double-intersection design in the large scale in Vietnam, especially, in the places where modern software is not used widely for designing intersections.
