Traffic Operation Analysis of D I Khan, Peshawar Motorway Interchanges through VISSIM

Abstract

Civil Engineering projects such as motorways are an important part of a county’s economic growth and are a sign on progress. They provide the people with comfort and ease of travelling to far off locations. Similarly, the Dera Ismail Khan-Peshawar Motorway will help bolster regional connectivity and connect two distinct portions of the nation through a series of interconnected highways. However, as civil engineers it is important to take into account the physical changes that projects tend to undergo with the passage of time in order to ensure the standard of service and predict any decline in performance and provide remedial measures if the need arises. To predict those changes VISSIM software was used to simulate various interchanges by providing the traffic data as input for three different years i.e. 2021, 2031 and 2041. Traffic data used for this process was provided by a traffic study report. Traffic for 2021 was provided by the study report while the traffic for 2031 and 2041 was calculated using different growth factors. Various parameters such as LOS, Stop Delay, Queue Length, maximum Queue Length and Vehicles delays were estimated. These parameters, prioritizing Level Of Service (LOS), were used to understand the performance of interchanges in the future. Any deterioration or decline in efficiency, if observed, was used to suggest remedial measures in order to improve the system and maintain maximum output of facility.
