Comparison Of Level Of Service Of Mirpur- 10 Circle Traffic Signal During Peak Hour And Off Peak Hour Using Highway Capacity Manual

Abstract

The increment of vehicles due to the proportional increment of populations and a rapid development of modern society is a major concern in Metropolitan cities in developing countries like Bangladesh. So, it is imperative to monitor traffic volume as well as the quality of transport supply termed as the Level of Service. The present study is an investigation of the behavior of mixed traffic flow in Dhaka city of Bangladesh. Field Traffic volume survey was carried out to determine the level of service at a major un-signalized intersections in Dhaka City Corporation. Level of service was determined by volume capacity ratio and peak hour factor method. Nature of traffic flow in Dhaka city is heavy. So, this heavy traffic are simplified by Passenger car unit. Then estimated passenger car unit was used to determine level of service. It was calculated for both directions of roads. bus, car, microbus, CNG and motorcycles are the dominant vehicles in Mirpur-10 intersection. According to peak hour factor method and V/C ratio method, level of service of Mirpur intersection is very unstable and heavy. It can be recommended that restriction for vehicle movement in daytime should be applied in Mirpur-10 intersection and width of Mirpur-10 to Pallabi and Mirpur 1 to Dhaka cantonment area road need to be increased to make the traffic flow suitable. Also, incorporation of an effective traffic signal, traffic rules and regulation should be applied and maintained properly in the worst condition intersection to accelerate the traffic flow in Dhaka City Corporation area.
