Currently Mergan 4-way intersection is one of intersection that have most traffic dense in Malang City, East Java - Indonesia. This research implement simulation method in order to give several solution option to manage the traffic queue in Mergan 4-way intersection. Simulation method is conducted with several phase, from problem identification up to verification and validation also scenario simulation. Arena Simulation software v.14 is chosen as the tool to modeling the traffic queue line. The research outcome give several solution through Traffic Light 2 simulation scenario. With this simulation scenario, the traffic flow system simulation can be run with fewer queues of vehicles.

Dinoyo T-junction is one of the intersections with the densest traffic in the city of Malang. This is because T-junction is connecting several major campuses in the Malang city and it is one of the main traffic lanes in town. This study conducted a simulation study of traffic queue on T-junction utilizing Arena simulation software, by giving some proposals solution through simple experiments. Research outcome show that a reduction of red lights duration by 15 seconds in traffic queue simulation for each segment on Dinoyo T-junction be able to gives a significant queue reduction result.
