Abstract

In the past years and with the start of Autumn and Winter seasons in Tehran, when vehicle emission rates reached their maximum amount in Tehran and According to the approved plan of the emergency committee for air pollution in Tehran, traffic congestion zone was extended to the Odd-Even plan area and many of the citizens changed their way of access to the area and other citizens paid the tolls to travel inside the zone with their private vehicles. In this research, first, the interviewees were asked to determine how they have traveled to the Odd-Even plan area. In the following, the proposed hypothesis was based on this assumption that if the traffic congestion zone due to the air pollution problem, is extended to Odd-Even plan area, According to the different scenarios, which travelling means they choose. After reviewing the results obtained from the questionnaire and using the Aimsun simulation software, the amount of emissions produced by the movement of vehicles when implementing the Odd-Even plan area within their range and the above scenarios have been investigated and evaluated. the results of this study show that the most ideal mode for reduction of pollutant values in the Odd-Even plan area, was with an increase of 40-75 % of the money allocated for the traffic congestion zone in the year of 2016 and with extending of that in the Odd-Even plan area, The relative abundance of travelling with non - public transport means, caused to reduce 21-23% and in parallel of reduction of travelling with non - public transport means, the amount of produced cars emissions for the CO, HC and NOX pollutants has been decreased 39, 36 and 30 percent in relation to the usual mode of implementation of the Odd-Even plan within its range, it will be reduced.
