Abstract Based on microsimulation, this study analyses the performance and behavior of motorized vehicles at the signalized intersection between the railway line and Ahmad Yani road-Jemursari road. For the survey of the volume of motorized vehicles, this intersection is divided into four intersections with eight directions of traffic movement and one direction of combined traffic movement. Microsimulation was carried out using Vissim software with nine parameters calibrated according to actual conditions during the peak hour observation period. The maximum queue length and motor vehicle delays for the peak hour observation period occur at intersections one in the north and two in the east. Performance of the intersection of Jl. Ahmad Yani-Jl. Jemursari is included in category F. The indicator F are traffic jams, low vehicle speeds, long queues, and vehicle delays. The following study of this paper is to make a geometric model of the intersection into a Fly Over model.
