Patal - Pusri Intersection is one of the intersections in Palembang with heavy traffic flow and frequent traffic jams. The existence of Underpass construction, apparently could not be a complete solution to unravel traffic congestion. The purpose of this research is to analyze five alternative scenario plans to disentangled the vehicle density, congestion, and reduce pollution from exhaust emissions caused by vehicle density. This research was conducted using VISSIM Microsimulation Program assistance to simulate existing alternative scenarios and to analyze the effect of these alternative scenarios on reducing vehicle exhaust emissions using the EnViVer Program assistance. The results showed that the fifth alternative scenario as the flyover construction, geometric changes at the intersection’s leg crossing, and traffic lights rearrangement became the most effective alternative and was able to parse vehicle density and traffic congestion, and was able to reduce exhaust emissions by 32.36%. This was shown by the reduction in queue length by 44% and the delay times by 57.05%, and the reduction in exhaust emissions in the form of carbon dioxide (CO2) by 35.5%, nitrogen oxides (NOx) by 43%, and particulate matter (PM10) ) by 18.6% at the intersection significantly.

Keywords : flyover, VISSIM Microsimulation Program, EnViVer Program, delay times, queue length, exhaust emissions.
