Scope

Scope: This document specifies the terms and definitions of phase differences between road networks, intersections, and road sections, and proposes design requirements for non-motorized traffic and public transportation phase differences from a planning perspective. This document applies to the planning, design, and evaluation of new and renovated urban roads of all levels, as well as related intersections, road sections, public transportation, and non-motorized traffic facilities within urban areas. Different-grade highways may refer to and implement it accordingly. Main technical content: - Traffic Function Level: Refers to the grade determined by the functional positioning and traffic characteristics of different roads, public transportation, and non-motorized facilities in the urban road traffic system. - Urban Road Level Difference: Refers to the difference in traffic function levels of road traffic facilities in the urban road traffic system. According to the traffic function and service objects of the phase differences in the road traffic network, it is divided into intersection phase differences, road section phase differences, public transportation phase differences, and non-motorized traffic phase differences. - Intersection Level Difference: Refers to the difference in traffic function levels of intersecting roads in the urban road traffic system. - Road Level Difference: Refers to the difference in traffic function levels of road sections in the urban road traffic system due to changes in lane scale or speed limits. Road section phase differences do not include special situations such as lane widening at intersections. When constructing or renovating urban roads, it is advisable to conduct overall design. In addition to considering intersections and road sections, efforts should also be made to optimize and guide the rational setting of road network phase differences. The planning and design of urban road phase differences primarily target motorized t
