A Study of Traffic Management at Different Intersections with Traffic Simulation

Abstract

The traffic congestion is caused from the origin and attracts a large amount of local travel and is rapidly expanding. From the statistics on passenger car registration, Chiang Mai is the second-largest in the country after Bangkok. (Information dated 30 March 2022). Effective traffic management can reduce travel delays and environmental impact. Traffic jams often occur when vehicles stop or slow down. Past studies have focused on reducing accidents and pollution problems, including solving traffic problems such as creating new routes, increasing, and expanding traffic lanes. This study examined traffic management patterns at intersections. Then, to increase service efficiency and select an intersections pattern that corresponds to the amount of traffic that occurs. Then, collecting traffic data including speed, travel time, flow rate, and traffic volume. Physical characteristics data collected was used as a case study. The microscopic traffic simulation was applied to analyze and compare the study results. This study defines different intersections management of 5 patterns, intersections with traffic signal lights and without traffic signal lights, general roundabouts and roundabouts with left-turn lanes, and compulsion of movement. This study will maximize the benefit of intersections management and understand the behavior of vehicles driving to intersections and the impact of traffic on different intersections patterns. This study used a basis to design the intersections patterns for traffic volumes in the future.
