In order to improve the safety and traffic capacity of the intersection, and reduce the delay of the intersection, this paper studies the safety adaptability of the intersection according to traffic flow characteristics and constraints of land resources at intersections in fast urbanized areas. A set of relatively complete indicators for the evaluation of the safety adaptability of highway intersections in rapid urbanization areas is proposed, and the weights of each indicators are determined. Combined with the engineering example of the intersection intersection in the rapid urbanization area of Ningbo, Zhejiang Province, the safety adaptability evaluation microscopic model of highway intersection is established by using the mathematical methods such as analytic hierarchy process, dynamic weight function and membership function. Provide theoretical and methodological support for traffic safety adaptability evaluation of intersections.
