Abstracts: India's urban population in 2010 was 356.38 million which is projected to be approximately 590 million by 2030, an increase of nearly 66%. In the face of this expected growth, it is critical to improve urban transport to ensure high quality of life in Indian cities, in terms of fast and reliable commutes, better air quality and public health, safe transport, and equitable mobility options for all sections of society. Growth of urban transport along a sustainable path in cities is the foremost need. The rapid urbanization in India has also resulted in a tremendous increase the number of motor vehicles. The vehicle fleets have even doubled in some cities in the last one decade. This increased mobility, however, come with a high price. As the number of vehicles continues to grow and the consequent congestion increases, vehicles are now becoming the main source of air pollution in urban India. A drastic increase in the number of vehicles has resulted in a significant increase in the emission load of various pollutants. Vehicles in major metropolitan cities are estimated to account for 70% of CO, 50% of HC, 30-40% of NOx, 30% of SPM and 10% of SO2 of the total pollution load. In which two-thirds is contributed by two wheelers alone. Performance of vehicle is assessed by driving cycles. i.e. vehicle operating modes (idling, cruise, acceleration, and deceleration). Driving cycle of vehicle has been used in emission estimation and fuel consumption study. Existing method of data collection using car chasing technique is expensive. The technique using micro simulation approach is cheaper and fast to derive the driving cycle. Analysis of driving cycle is used for sustainable development of transportation system, traffic demand management, signal coordination, and environment friendly application for Intelligent Transportation System (ITS).
