Evaluation of traffic strategies on pollutant emission of vehicles (Case study: Shahid hakim highway)

Pollution crisis has become one of the most complicated problems which outbreaks the urban management in charge groups of the capital Tehran, and many strategies have been used to control this problem. In this case, using simulation is one of the best tools to predict the driver behavior and also the speed and the acceleration of vehicles in the network. As well as using the pollutant emission models combined with traffic simulation software can provide a suitable prediction tool to predict the pollutants produced by urban transportation network. In this research, after studying the vehicle following models based on acceleration and velocity prediction, and beside some bases of instantaneous emission models, an urban highway in the capital Tehran was investigated. In the investigation both odd and even approach and limitation in speed of vehicles approach were supposed. Comparison the results achieved from both approaches with the ordinary conditions of the network, showed that using the odd and even approach can reduce the pollution to 50% in general. But due to the provisional conditions of this strategy some other suggestions are given in this paper.
