ANALISIS DAN KOORDINASI SIMPANG KARTINI DAN SIMPANG SIDODADI SEMARANG

Abstract

The traffic growth volume continues to rise rapidly, especially in the city of semarang. This makes the occurrence of the traffic congestion during the rush hour especially at the intersection, one of the roads as well as on the road Dr. Cipto Semarang. This analysis aims to expedite traffic on the road Dr. Cipto by way of coordinating intersection and intersection Sidodadi Kartini. Survey data was collected directly at the second intersection at peak hours in the morning, afternoon, and evening. The data used is the flow of the vehicle, signal timing, vehicle travel speed, queue length, and geometric intersection. The survey results are then processed using the guidelines Manual Kapasitas Jalan Indonesia (MKJI) 1997. Analysis calculated intersection with three conditions, namely existing, optimally, and scenarios. After comparing the results obtained between the existing, optimized, and the scenario it was decided to use the optimal conditions due to a better outcome. Then do the coordination with the optimal conditions, to coordinate both the signalized intersection, the planning is done is to equate the two junctions cycle time, in the morning peak hour cycle time 82 seconds, 75 seconds at afternoon, and 100 seconds at evening. From the distance between the intersection and the vehicle speed obtained offset value is 36 seconds while the bandwidth at peak hours in the morning for 25 seconds, 22 seconds during afternoon, and 32 seconds at evening. While the efficiency of the coordination of the two intersections of 30.48% for the morning, 29.33% for the afternoon, and 32% for the evening. Performance of coordination is good enough for the level of short-term treatment. Thus, it can be concluded that the performance of the intersection is reviewed to be better than the initial condition.
