Research on Classification System of Urban Roads in Shanghai

During past decade, to improve the urban roads operating efficiency, many efforts had been made to adjust road spatial scale, but the key matter should be a suitable classes structure of urban roads, which primary depends on a reasonable classification system. Through analysis of different classification systems of urban roads abroad and at home, according to Shanghai's traffic mode characteristic, this paper put forward a new one applied in Shanghai, which divides urban roads into four categories and seven classes and also defines their corresponding planning, design, construction and management standards. The author hope the implementation of this kind of urban roads classification system can boost road capacity and improve urban road network operating quality.
