The increase in the number of motorcycles in Indian cities is due to several factors such as traffic, low cost, mobility, few parking lots and the low efficiency of public transportation, becoming an important factor in air quality deterioration. In this context, vehicle emissions monitoring is essential to understand the contribution to air pollution as a whole. . The development of models for air pollution assessment has been identified as an important area for future research. Air pollution due to massive use of motor vehicles in urban areas of India is one of the most serious and the fastest growing problem to solve. These motor vehicles emit significant quantities of CO2, CO, hydrocarbons, oxides of nitrogen, SPM and other toxic substances in the atmosphere which adversely affect the environmental and the health. The objective of this study is to understand the chemistry of air pollution with its precise estimation through modeling. The behavior and relation between emission and deposition of pollutants can explain with the help of air quality models. Modeling is a set of different scientific methods that are helpful to analyse the nature and behavior of pollutants in the atmosphere. On the basis of source of pollutant air quality models are classified as point, area or line source models. Various Gaussian based line source models are commonly used in India to assess the impact of vehicular pollution along the roads or highways. The CO pollutant concentration values were compared with the National Ambient Air Quality Standards (NAAQS), and the CO values were predicted by using CALINE4 model. The possible association between CO pollutant concentration and traffic parameters like traffic flow, type of vehicle, and Roadway width was also evaluated.
