The Implementation of Dynamic Traffic Light Model to Overcome Traffic Congestion in Denpasar - Bali

Traffic congestion is a problem that often occurs in a city like Denpasar. Congestion occurs due to the factor of poor government regulations such as the lack of public transport, the increase in the number of vehicles which is not accompanied with the expansion of roads, as well as poor spatial planning of the city. The imbalance in the volume of vehicles crossing the road also contributes to the problem especially at intersections. At every intersection in the city of Denpasar, to avoid accidents, the government installs traffic light. Unfortunately, the traffic light is statically setup with each green light for every direction is given the same time period. This is also predicted to be one of the factors causing congestion in the city of Denpasar, because it does not take into account the density of the volume of vehicles coming from certain directions. From the result of surveys conducted at the intersection of By Pass Ngurah Rai Denpasar, static traffic light contributes to the accumulation of vehicles ranges from 53 to 87 per hour which in turn causes traffic jams. To overcome the bottlenecks that often occur, in this study we propose a dynamic traffic light model which produces green light time difference of 3.986 minutes to 6.543 minutes to every hour with a significance level of p 0.012 0.072 which is able to parse the vehicle density of about 53 to 87 per hour. The dynamic traffic light model is appropriate to be applied at intersections in Denpasar considering regulations related to public transportation and administration area which are less supportive. The density of vehicles which can not be avoided must be parsed quickly so as not to cause traffic jams everywhere.
