SUrban interchange design not only needs to consider factors such as traffic flow, technical indicators, environmental conditions, etc., compared with highway interchanges, it is limited by land use planning, subway, topography, building safety clearance and other conditions, and additional roads and pedestrian non-slow travel systems are added. There are many factors to consider in the design of urban interchanges, and the complexity is different from that of highway interchanges. Taking Luoyang urban interchange design as an example, this paper summarizes and analyzes the consideration factors and design optimization points of urban interchange design.
