TRAFFIC IMPACT ANALYSIS OF NEW-RESIDENTIAL SCHEMES IN THE VICINITY OF ISLAMABAD AIRPORT OVER MAJOR INTERSECTIONS OF N-5

Abstract

A traffic impact analysis is a method to evaluate whether the transportation infrastructure is enough now or in the future to handle more trips brought on by a proposed construction, redevelopment, or land rezoning. In this study, the impact of current traffic volume and traffic volume being generated by new housing societies on the existing road network concerning development years is analyzed. The analysis is done on the road network with do-nothing, do-minimum and do-something scenarios. The analysis is based upon some parameters: travel time, the value of travel time and vehicle operating cost. For the calculation of these parameters, the HCM method, HDM-4 Model used in NTRC Study, Hepburn Model and Synchro software are used. Traffic Impact is analyzed as a difference in monetary terms of these parameters due to differences in traffic volume due to different years of development, increase or decrease in travel time and variation in vehicle operating cost as well as due to different scenarios development.
