The better of society welfare makes the development rate of traffic as a means transportation is increasing as well. On the crossroad of Suprapto and Imam Bonjol street in Palangka Raya city, traffic conflicts often happened there due to the flow of traffic at the intersection is quite crowd in the morning, afternoon and evening. This study was conducted to analyze the performance of intersection by using MKJI done by comparing the time of red, green and circle time with the analysis results due to the changes in volume today. By using MKJI method, the variable is the size of the city, geometric, direction of flow, volume, velocity and phase. The results of the field survey dan the result of the analysis so the level of service and utilization of signal light at Suprapto – Imam Bonjol is good enough, but for the using of traffic light at the intersection is still needed because of the degree of saturation (DS) on pendekat North = 0.618, Pendekat West = 0.635 and Pendekat East = 0.364 which still meets the standard value of Degree of Saturation, that is ≤ 0.85 with an average delay of 2.83 sec/smp, and it means that the crossroad did not have traffic jams during rush hour. At this crossroad, it does not need any setting with traffic lights, but it is enough to be paired in median only.

Jalan Temanggung Tilung is a 2/2 UD type road (two undirected two-way lanes) with a road width of 5.5 meters, which is a connecting road between two major roads, namely the RTA road. Milono and the path of G. Obos. Over time, the volume of traffic through these roads increases every year, plus roadside activities that also increase cause congestion at several points of the way. To overcome this problem, the local government carried out road widening to increase the capacity and level of road services. The study was conducted to determine the amount of traffic volume, performance, service level of the Temanggung Tilung road section at peak traffic hours before and after road widening. Data retrieval is done by the direct survey to the field to obtain primary data in the form of geometric road data, two-way traffic volume data, and side obstacle data. Performance analysis refers to the 1997 Indonesian Road Capacity Manual (MKJI) for urban roads. From the results of data processing, before increasing the road (Type 2/2 UD), the traffic volume that passes through the path is 842 pcs/hour and after road widening (Type 4/2 UD) the traffic volume for two directions is 973 pcs/hour, with route A equaling 528 pcs/hour and direction B equaling 445 pcs/hour. Based on the analysis of road performance before road enhancement, the capacity = 2551 pcs/hour, saturation degree = 0.331, and the service level of the two-way road are level B. Based on the analysis of the performance of the way after increasing the way, the direction capacity A = 2686 pcs/hour and direction B = 2674 pcs /hour, saturation degree for direction A = 0.196 and direction B = 0.166, service level for road direction A and direction B increase to level A
