A Treatment of Signalized Intersections with High V/c Ratio Under Advanced Traffic Control Systems

Abstract

Advanced Traffic Control Systems (ATCS) have been recognized as one of the most direct methods for relieving urban traffic congestion. However, the application of the systems in developing countries is unique because road intersections in their cities are usually very congested with high v/c ratio. The aim of this study is to evaluate the treatments of signalized in-tersections with high v/c ratio under ATCS. Moreover, is to recommend how to improve traffic performance in an existing severe transportation problem. Road network in Bandung-Indonesia was used as a case study. AIMSUN (Advanced Interactive Microscopic Simulation for Urban and Un-urban Network) micro-simulator was conducted to evaluate the treat-ment during peak and off peak periods. The results indicate that by chang-ing two-way into one-way road will cause an increase in traffic flows by 7%-58%, and a decrease in queue length by 87%-100%. In general, all performance measures in related streams were bette
