The evaluation of traffic performance at several signalized intersections using 1997 Indonesian hIghway Capacity Manual

Since 1997, the Government of Bandung area has already installed the ATCS (Area Traffic Control System) to control the vehicle movements in the intersections. Traffic counts at signalized intersection were detect via wire detector and automatically connected to the Traffic Control Centre (TCC) of ATCS, the TCC will automatically arrange, cycle times, green lights, ambers, red lights for every intersection which are connected to the ATCS. Indonesian Highway Capacity Manual (IHCM) 1997 is applied as a tool in planning, design and operational analysis of road traffic facilities, can predict the performance of traffic light for a given set traffic, geometric, and environmental conditions. The objective of the research is to evaluate the performance of many intersections using the 1997 IHCM. The phases, cycle times, green times, amber and red lights for several intersections will be compared to those obtained by ATCS. The performance of many intersections will be expected to perform better, so the traffic jam such as delay and queuing could be reduced.
