MICROSIMULATION OF URBAN TRAFFIC FLOW- A CASE STUDY OF UNIVERSITY ROAD PESHAWAR, PAKISTAN

Abstract

Traffic cramming is a serious problem in urban areas of Pakistan particularly in Peshawar. A pilot scale survey was performed regarding traffic volume and travel time data, vehicle specifications and geometry of the study area and analysis were performed that can be applied to the remaining section of the University road. Calibration and validation of model was done by comparing the field results of traffic volume and travel time with results obtained from the micro simulation. After analysis for queue delays, travel time and traffic flow versus travel time data for different traffic scenarios, maximum queue lengths and queue stops were observed near U-turning and Right-turning locations. At selected section, the average speed was found considerably lower than the design. An option of roundabout and a flyover were used in analysis. Queue delays travel time reduce near U-turns and all the right turning locations of study area with provision of roundabout or flyover. With provision of flyover, results for traffic flow and delay were improved.
