Development of Road Network Traffic Model in Bandung City

Abstract

The city of Bandung is a city with a higher number of movements; thus, it allows congestion on certain road segments. Constructing and widening new roads do not become the only solutions, but also by improving the traffic management on these roads. With the study area in some segments of Wastu Kencana Street, Cihampelas, Pajajaran, Pasir Kaliki, Kebon Kawung, and Cicendo, some of which have frequent congestion. Several alternatives have been assessed to implement traffic management policies. The solution alternatives are do nothing and do something. Do nothing alternative means the existing road conditions at the time of the study. Do something alternative consists of three traffic management scenarios: Alternative 1, changing traffic direction but not changing the existing one-way system; Alternative 2, applying a combination of one-way systems with two-way systems; and alternative 3, applying a condition of traffic management using two-way system in all roads. Whereas to evaluate network performance, the cost parameters of the trip, the average Volume Capacity Ratio (V/C), and the average speed are employed. The best policy alternative is Alternative 1 where the V/C value is 0.72, average speed of 27.57 km/hour, and cost of travel of IDR 9,370.87 million/hour.
