Improving the Traffic Flow for Kajang Town by using TRANSYT-7F Software

Abstract

The rapid population growth of Kajang town and the increase in the number of vehicles have caused an increase in the daily trips made on most streets and at the intersections of the town, especially during peak hours. This has worsened the traffic congestion on the road networks. This study aims to evaluate the existing level of service (LOS) and coordinate the traffic signals in order to enhance the efficiency of road junction networks in Kajang. The traffic data at 15 intersections were gathered via video recording during the morning peak hour. This study used the Traffic Network Study Tool Version 7F (TRANSYT-7F) software to analyzing and evaluating the performance of road junction networks based on simulation and signal timing optimization. The results show that the software was able to improve the performance of network intersections. The performance index (PI) increased to 44% and fuel consumptions (FUC) were reduced 25.7% and reduced average delay from 85.5 Veh/Sec to 28.9 Veh/Sec. Hence, the level of service (LOS), system speed and average delay were also improved by the coordination of the traffic signals.
