| Abstract | Among all the development sectors, transportation is the single one which brings problem with economic and social improvement. Air pollution is a major byproduct of transportation system. In many countries, considerable effort has been made to develop clean transport systems by using technical, economic and planning instruments. However, the overall impacts of these policies are still not very clear. This study is aimed to investigate and compare the impacts of demand and supply based transportation policies on air quality with the help of system dynamic modeling technique. Concerning variables related to the policy implications are identified and inter-variable relationships are established by analyzing the underlying causal structure of the overall system. An emission measuring model named MOBILE6 was also used in connection with the calculation of emissions. Results of the study show an initial improvement of air quality for supply based measure (added lane). However, in the long run, it failed to get benefit over demand based policy. Whereas, demand based policy (using an existing lane as segregated bus lane) initially raises the pollution level but subsequent downward drifting of vehicular demand brings considerable improvement on air quality. The results indicate the importance of adopting demand based policies for sustainable air quality improvement. Transportation professionals are often impelled to assess the merit of their policy and planning before real world implementation. The framework of this study will help the transport policy makers to evaluate and choose the sustainable pollution control strategies by examining the relative strength and weakness of the alternatives |
