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 (LOS). The present study is an investigation of the behavior of mixed traffic flow in Dhaka Mirpur-10 city of Bangladesh. Field Traffic volume survey was carried out to determine the level of service at 3 major Unfinalized intersections in Dhaka north city corporation (DNCC). Level of service (LOS) was determined by volume capacity ratio and peak hour factor (PHF) method. Nature of traffic flow in Dhaka Mirpur-10 city is heterogeneous. So, this heterogeneous or mixed traffic are simplified by Passenger car unit (PCU). Then estimated PCU was used to determine LOS. LOS was calculated for both directions of roads. Car, CNG, Private Car, rickshaw and bike are the dominant vehicles in Manicotti, Mirpur-10. According to PHF method and V/C ratio method, LOS of Manicotti intersection is very unstable and worst. Residential area is very worst in nature after analyzing both V/C ratio and PHF method. Considering and evaluating all the findings it can be recommended that Restriction for truck movement in daytime should be applied in Manicotti intersection and width. Also, incorporation of an effective traffic signal, traffic rules and regulation should be applied and maintained properly in the worst condition intersection should be extra bike lane rout system the traffic flow in Mirpur-10 DNCC area.
