To develop transportation systems tailored to the unique characteristics of different cities and clearly define cars'role in these systems,this research first established a multi-level evaluation system representing the urban traffic situation in terms of external environment and traffic tools.Based on the first-level index scores,the traffic characteristics of nine selected typical cities in China were analyzed and classified into clusters.Subsequently,using multiple regression analysis,the main factors affecting urban road traffic were identified.Finally,by assuming scenarios of changes in related factors,the potential evolution of road traffic efficiency in each city was predicted,leading to the formulation of relevant policy suggestions.
