INTEGRATED AND COORDINATED TRAFFIC MANAGEMENT BASED ON CENTRAL BUSINESS DISTRICT IN MAKASSAR CITY INDONESIA

The research objective is to evaluate the performance of intersections around the central area of urban activities, analyze queues and delays that occur in the area, openings and existing canalization, analyze the level of accessibility from the influence of traffic management, from obstacles to various privacy activities, determine the optimization of traffic light functions coordinated and integrated. The research method is generally carried out through direct surveys, mathematical analysis and comparative analysis. Mathematical analysis is done iteratively to get the best cycle time as an integrated and coordinated intersection function. Graphically, it can facilitate the drawing and reading of the best cycle times for various intersections that are included in the design. The results obtained showed that the densest traffic volume in the CBD area occurred at the intersection 7 and 12, with the 42.02–72.59% composed of vehicles dominated by motorbikes, while jeeps between 6.72 – 35. 63%. The capacity of Intersection in this area averages 6,809 passenger car unit (pcu) / hour, so that the Degree of Saturation averages 0.895 with the maximum is 0.917. The highest chance of queuing occurs in unsignalized intersections in the CBD area between 42-84% which occur at the intersection 7 and 12 with the highest delay was 38.18 seconds (intersection 2). The level of accessibility of this region was high but because of the high side barrier. Intersection capacity improvement through geometric improvements, channelization, improvement and optimization of integrative traffic light functions, has the potential to contribute up to 36% and based on simulations with VISSIM program aids until the projections for 2025 can be maintained contributing to an increase in capacity of up to 22%
