Pabna is one of the major developing city in Bangladesh which is not blessed enough in terms of transportation facilities. This study primarily focused on the peak hour factor and level of service of Traffic More road intersection in Pabna city. The data analysis result shows that the level of service of major intersection covering connected roads of Pabna city such as Hospital road, Abdul Hamid road and Pabna-Ishwardi highway road varies from A to C at different consecutive days of the week, where “A” represents the free flow of traffic and “C” represents the traffic flow with some delay. Lack of footpath, temporary street site shops and illegal parking is the main reasons for this situation. In this regard this situation can be controlled through improvement of existing road network and proper traffic management system. Keywords: Peak hour factor, Level of Service (LOS); Passenger Car Units (PCU); Volume Capacity Ratio. 1 Introduction In Bangladesh, the efficiency of road network is termed as a catalyst to solve all the transportation problems (Sharmeen, et al., 2012). Transportation system directs the urban development pattern (Saha, et al., 2013), therefore the improved transportation system is one of the major key of all kinds of development. With various structural and infrastructural improvement of the Pabna city, numerous industries, educational institutions, financial banks, offices, hotel and restaurants etc. are established. SQUARE is one of the top leading industry of Bangladesh which is situated in Pabna city. In this regard people from various parts of the northern Bangladesh are coming to Pabna for a job. As a result, the non-local population of Pabna is rising very rapidly, on the other hand to support increasing number of city people, the number of various types of vehicles such as auto rickshaw, rickshaw, CNG, motorbike is increasing day by day. Due to rapid population growth and the increasing number of various types of vehicles, in present times the traffic management system is becoming worse in Pabna city. As a result traffic congestion becomes a daily occurrence in this locality. In Pabna city, the nature of traffic flow is heterogeneous. During the peak hours it is very common to see traffic congestions at major intersection area. In this regard the aim of this study is to find out the characteristics and the conditions of Level of Service (LOS) on Traffic More intersection area of Pabna city. Traffic More is one of the major intersections of Pabna city which connects three major roads named Abdul Hamid road, Hospital Road and Pabna-Ishwardi Highway. Level of service is used as a tool for evaluating the success and efficiency of Traffic More. Traffic volume survey and roadside interview survey method has been carried out to identify the level of service of Traffic More intersection. The determination of level of service is done on the basis of Highway Capacity Manual (HCM). It is a qualitative measure which generally describes the operational conditions within a traffic stream. The study shows that the level of service at the roads intersection varies in different consecutive days of the week. There is indispensable need of required level of service in major intersection connecting roads, as lower level of service leads to excessive delays and driver’s frustrations. Efficiency of road network can be achieved through compatible transportation planning and impact assessment of existing transportation system. In this regard this study aims to provide some recommendations from the analyzed scenario of the study area to reduce the traffic congestion problem and to ensure proper traffic flow for urban dwellers, therefore this study can be helpful for concern authority for planning and designing new roads, accident analysis and future traffic demand forecasting for Pabna city.
