Traffic Mitigation on the National Highway Number 3242 (Ekachai Road)

Abstract

The National Highway Number 3242 or Ekachai Road, currently, has high traffic volume. As a result, traffic congestion accumulated over a distance of 1.80 kilometers. Based on field studies, there are two major reasons causing such traffic congestion: 1) inadequate of travel lanes, and 2) improper traffic management at Bangbon 3 intersection. In this study, each solution was analyzed and compared using traffic simulation model. It was found that improving traffic signal at Bangbon 3 intersection along with the addition of traffic lanes at Ekachai interchange increased average speed of vehicles and reduced travel time by 20.5 percent and 20.4 percent, respectively.
