With the development of urban road traffic, Chinese vehicle industry is expanding in recent years, which has got splendent achievement. There is a intimate relationship between urban road traffic and vehicle industry, and the improvement of urban road traffic has a positive effect on vehicle industry. By making annual vehicle marketing amount as dependent variable with urban road length and urban road area taken as main independent variables ,the paper analyses the influence of urban road traffic on vehicle industry by estabishing the linear regreesion model and does reasonable forecast on the development of future vehicle industry,which provides a certain basis of formulating vehicle industry for vehicle enterprise and government.
