Technical Evaluation and Comparison of Odd-Even Traffic Restriction with District Pricing Policy in Reduction of Emissions Generated from Transportation Vehicles (Case Study: Selected Area of Tehran City)

In Recent years, different Traffic schemes such as the Odd-Even day plan starting from the door of each house or the extension of traffic congestion zone to the Odd-Even plan range have been implemented when vehicle emission rates reached their maximum amount in Tehran. In this study, according to the approved plan of the Emergency Committee for air pollution in Tehran to extend traffic congestion zone to the Odd-Even plan range in Tehran in the third and fourth week of November 2016 and by using the information obtained from the amount of personal car usage of citizens in a selected area of Tehran, which includes 15 intersections and their traffic statistics harvested by the SCATS system, the volume of cars and their emissions rate in this zone during the above-mentioned period and also in the second week of November and the first week of December 2016, during which the Odd-Even plan was also in effect, was simulated and calculated with Aimsun Simulation software. In another stage of this research by using distributed The results shows that during the weeks that Tehran traffic congestion zone extended to the Odd-Even plan range, and Specifically the comparison for the first day of implementation of traffic congestion zone in the range of Odd-Even plan with the same day in the previous week (implementation of Odd-Even plan range) in this research, produced cars emissions for the CO, HC and NOx pollutants has been decreased 20, 18 and 14 percent.
