The evaluation of traffic characteristic analyzed by vissim (case study: Underpass construction at Metro Pondok Indah Road)

Abstract

Government of DKI Jakarta build road infrastructure such as fly over and/or underpass to reduce congestion and delay at the main junctions. One of that is underpass construction at Metro Pondok Indah Road. The impact of this project during construction is make the road narrowing (bottleneck) and cause longer travel time of vehicle and decreased average speed. This research tries to simulate this situation using Vissim as a modeling traffic tool and then compared with actual conditions. Some calibrations of driving behavior parameters have been done using GEH formula to adjust the parameter to the acceptance level at value less than 5.0, so it can conclude that simulation using Vissim can represent actual condition during traffic congestion and normal condition especially in Jakarta traffic. These adjusted parameters may represent the actual traffic condition in Jakarta.
