A Traffic Volume Study Between Khamarbari and Aarong Junction in Dhaka City

Abstract

Volume study is an essential measure to determine the service of a road and study the need for any change to the current transportation system. Traffic volume studies are conducted to determine the number, movements, and classifications of roadway vehicles at a given location. These data can help identify critical flow periods, determine the influence of large vehicles or pedestrians on vehicular traffic flow, or document traffic volume trends. In the absence of effective planning and traffic management of the city, the current road infrastructure cannot cater to the future needs of the city. The current work studies traffic characteristics in the city of Dhaka at one selected priority junction. Volume survey was conducted by myself and my fellow groupmates on the Khamarbari and Aarong junction with a view to gaining data and insight about the traffic parameters and conditions in this road. We collected seven days data for the survey and conducted the survey of volume study using manual counting method. Before starting the final survey, we did a reconnaissance survey for 10 minutes for identifying a suitable location. We also conducted piloting for five minutes for the purpose to find out any problems that were related to the volume study. Then we started the final survey. This study analyzes the data to form an idea about vehicle composition in the traffic stream, service flow rate, directional distribution, estimation of ADT and AADT. Finally, the results from this report would be helpful for better understanding the roadway capacity, demand and overall conditions of that route and can be used for any future project or expansion of this road
