<![CDATA[On-street parking is a common problem on commercial urban roads, especially where roadside activities are high and off-street parking is limited. On Jalan Kanggraksan, Cirebon, parked vehicles occupy part of the carriageway and reduce the space available for through traffic. This paper examines how this condition affects the performance of the road segment using PTV Vissim microsimulation. Field surveys were carried out for four days to record road geometry, traffic volume, vehicle speed, and roadside activities. The model was calibrated through driving-behavior parameters and checked using the GEH statistic. The GEH values were 0.42 for Direction 1 and 0.86 for Direction 2, showing that the simulated traffic volumes were close to the observed volumes. Two conditions were then compared: the existing condition with on-street parking and a no-parking scenario. Under existing conditions, Direction 1 recorded an average speed of 15.84 km/h, 16.22 s/vehicle delay, and LOS C, while Direction 2 recorded 22.23 km/h, 11.59 s/vehicle delay, and LOS B. When on-street parking was removed, the speed increased to 19.48 km/h in Direction 1 and 34.75 km/h in Direction 2, with delays decreasing to 7.77 and 2.76 s/vehicle. Both directions improved to LOS A. The results suggest that targeted parking control can noticeably improve traffic operation on commercial arterial corridors with similar roadside characteristics.]]>
