A classification method for accesses on suburban highway

Abstract

To increase the capacity and to improve the safety on suburban highway, this paper proposes a classification method for access on suburban highway based on the roadside land use type. Considering the standards in China and the field survey, three access categories are defined as follows: Category 1: large residential district or business district; Category 2: hybrid district of commerce and residence; and Category 3: shops along street. The rationality of classification is verified by significance test, which shows that the three categories exhibit significant difference and affect the traffic flow on main road traffic in different degrees. Therefore, the proposed classification method can be used for the basis of relevant researches on suburban highway accesses.
