Scope

Scope: This document specifies the relevant content of the design of the connection between ordinary national and provincial highways and urban roads, including connection modes, networks, nodes, and cross-sections, and is applicable to the design of new and reconstructed projects, as well as the municipalization transformation of ordinary national and provincial highways at their connections with urban roads. Main technical content: The chapters of this standard include: scope, normative referenced documents, terms and definitions, general principles, connection modes, connection networks, connection nodes, connection cross-sections, municipalization transformation, and clause explanations. Among them, "connection nodes" and "connection cross-sections" are the main technical content of this standard. This standard specifies the spacing between adjacent interchanges, the minimum spacing of planar intersections, and the minimum spacing of right-turn and left-turn controlled planar intersections, as well as the optimal spacing of planar intersections. The connection cross-section scheme provides recommended design elements for different types of connection cross-sections. Main technical indicators and parameters: The main technical parameters of this standard are "the spacing between adjacent interchanges, the minimum spacing of planar intersections, and the minimum spacing of right-turn and left-turn controlled planar intersections, as well as the design elements of connection cross-sections". The calculation method is: the spacing between adjacent interchanges, the minimum spacing of planar intersections, and the minimum spacing of right-turn and left-turn controlled planar intersections, as well as the design elements of connection cross-sections are determined according to current standards and specifications. The equilibrium point of planar intersection spacing is obtained by analyzing the spacing between urban interchange nodes in Fengcheng City, Yichun City
