Traffic growth in Yogyakarta is increasing rapidly because it is an educational and tourist destination. This has an impact on increased traffic, conflicts and congestion due to limited road capacity. This problem often occurs at an intersection that does not have a signal, one of which is the intersection of Jalan Mataram Sewer and Jalan Wahid Hasyim, resulting in congestion with long queues at the intersection. Therefore, this study aims to model the performance of these intersections in the existing conditions and conditions if given the APILL signaling. The results showed the performance of intersections in the existing poor condition with the level of service (LOS) E and a delay of 56.27 seconds / vehicle and an average queue of 81.65 m. Simulation / modeling with APILL in scenario 1 shows the results of the level of service (LOS) E, with an average delay of 72.17 seconds / vehicle and an average queue of 124.45 m while scenario 2 shows the level of service or level of service (LOS) F, with an average delay of 83.45 seconds / vehicle and an average queue of 121.52 m. Existing modeling has a better level of service than scenarios 1 and 2 because there is no delay due to APILL lights but in scenario 1 with increasing delays nevertheless traffic at the intersection provide safety for road users.
