Abstract Sakra 4-way intersection is one of the unsignalled intersections in East Lombok. At certain times of the day, there are frequent traffic jams and queues of moving vehicles at this intersection because the area surrounding the intersection is a commercial area, as evidenced by the presence of settlements, markets, mosques, village heads’ offices, shops, and other shopping centers. This research aims to determine the movement of traffic flow at the 4-way Sakra intersections in East Lombok using Vissim software modeling. Data collection was obtained from literature studies and direct surveys at the research site. Direct questionnaires at the research location and literature reviews were used to collect data. Using PTV VISSIM software modeling, the intersection of Sakra East Lombok was modeled under the current conditions on Monday and Sunday. The results showed that values for Monday were Queue Length (Qlen) 34.77 m and Tundaan (VehDelay) 19.95 sec / skr. The value of Tundaan (VehDelay) on Sundays is 16.68 sec/skr, the value of Queue Length (Qlen) on Sundays is 23.76 m, and the service level of the junction (LOS) on Monday and Sunday is C (not good). And for the movement of vehicle flow passing at intersection 4 Sakra East Lombok, which indicates the density of vehicles traffic flow is moderate, internal traffic barriers begin to affect speed and drivers still have adequate discretion over their speed and the lane they use on the road.
