The signalized intersection on the case study area continued getting worse in recent times due to the increasing traffic volume. To increase the level of service, treatment is carried out by adding a special left turn lanes of Sarwo Edhi Wibowo Street (named sodetan road). The research was conducted to analyze the effectiveness of adding left-turn lane to increase the intersection capacity. Analysis method using Pedoman Kapasitas Jalan Indonesi (PKJI) 2014. Based on the analysis results, the snooze value and queue length decreased in the observation area (sodetan road), but the decrease in the average delay value of all approach lanes was not significant enough. Unfortunately, the level of service with or without the new road has not changed, still worse (F). Widening road in the form of the addition of sodetan road at this signalized intersections turns out not to be very effective in solving congestion problems. This research is expected to be a recommendation for related agencies in improving the performance of the signalized intersection and can be considered in the development of policies related to the effectiveness of widening the road or adding lanes at other intersections in reducing congestion at intersections.
