Abstract: This research paper presents an overview of methods of engine emissions controlling related to automotive fleet and road traffic characteristics. As urban populations expand and city roads become increasingly congested, city planners need comprehensive urban development and transport strategies to address deep-seated social and demographic change.
Effective policies must meet multiple objectives:
-Establishing a balance between different modes of transport: public transport, cars, motorcycles, bicycles, and pedestrians;
-Providing security, safety and optimum service for transport system users;
-Maintaining the urban mobility that drives economic development;
-Reducing urban pollution caused by motor vehicles by controlling emissions.
Nowadays urban pollution exposure from road transport has become a great concern in major cities throughout the world, for this reasons is presented the most used active and passive methods for controlling the motor vehicle emissions.
In this paper, it were presented results obtained using a model software ADMS - Urban, on which ADMS-Roads is based, for air quality management and assessment studies of complex situations in towns, motorways, counties and large industrial areas. The ADMS model uses advanced algorithms for the height-dependence of all variables including traffic flows, traffic speeds, emission rates, and the wind speed, turbulence and stability to produce improved predictions.
