Mokodompit Street – M.T. Haryono – H.A. Nasution is one of the signalized intersections in Kendari City which has congestion problems, vehicle accumulation and vehicle queues at each arm of the intersection at rush hour due to the large volume of traffic flow and not optimal cycle timing from the traffic light signal. The purpose of this study is to optimize the cycle time of traffic control light signals based on traffic volume and to analyze the performance of these intersections. The results of the analysis based on the volume of traffic flow obtained the optimal cycle time of 72 seconds with the division of green time in each approach by 18 seconds for the north approach, 14 seconds for the eastern approach and 28 seconds for the south approach. The degree of saturation at each intersection arm is 0.82 which is at the service level D. Keywords: Signalized Intersection; Optimal Cycle Time; Service Level 1. Introduction An intersection is a location/area where two or more roads join or intersect/cross. The most common types of intersections in urban areas are unmarked intersections. This type is suitable to be applied to traffic flow on minor roads and relatively small turning movements, however, the traffic on the main road is very high so that accidents for motorists on minor roads are increasing, so it is necessary to have traffic lights [7]. Intersection planning with traffic light control must be planned properly and in accordance with traffic flow needs, because inappropriate planning will lead to new conflicts in intersections with the emergence of larger traffic delays, long queues and decreased intersection capacity as a result due to a malfunctioning of the intersection optimally [6] Intersection on H.E.A Mokodompit Street – M.T. Haryono – H.A. Nasution is one of the intersections with signals in Kendari City and is better known as the New Campus intersection because it is located at the entrance to the New Campus of Halu Oleo University (UHO). This intersection is an intersection with type IT 322 which is in an area with a very large traffic pull because apart from being an educational area, in this area there are also other public facilities such as banking facilities and shopping places so that congestion is not uncommon at the intersection.
