Analisa Manajemen Lalu Lintas Meningkatkan Tingkat Pelayanan Jaringan Jalan Menuju Pusat Kota Medan

Abstract

The problems traffic on the road network in Medan are a distinctive phenomenon to be considered. They are handled proportionally especially by means of a short term action plan at the location contained many signalized intersection with a distance of adjacent, one of which by means of coordination of some crossroads at the location under the study. Survey data was collected directly at the second intersection at peak hours in the morning and evening. The data used is the traffic volume, signal timing, vehicle travel speed, queue length, and geometric intersection. The existing speed of 34 Km/hours, obtained by the time offset of 38 seconds and a cycle time of 85 seconds. After doing the coordination and dissimilation of the crossroads by means of trial and error at the concerned locations, the crossroads functions has increased compared to the current condition of prior coordination crossroads. The coordinated crossroads are capable to reduce the time delay, at crossroads 1 time delay of 25.15 smp/sec decreasing delay time of 25.04 smp/sec Index Level of Service C. While at crossroads 2 delay time of 41.88 smp/sec decreased the delay time of 36.91 smp/sec Index Level of Service C, as a percentage of performance improvement of 12% from the previous
