Abstract： Aiming at the controversies in red line planning of urban intersections under the new situation, this paper first clarifies the relationship between red line planning and intersection functional design. By analyzing the domestic and international intersection design specifications, practices, trends and differences, the paper proposes the basic principles for red line planning at intersections in several aspects: transformation of development concept and design, coordination between the spatial certainty and functional uncertainty, and policy and system support. Based on the requirement from the new development concept and the characteristics of urban development, the paper presents the method of widening the intersection red line considering the boundary spacing of roadway network and for the red line corner cut at intersections with different functionality types. Finally, the paper provides several thoughts on the red line planning of intersections in system structure and policies, methodologies, historic viewpoint, and etc.
