摘　　要：针对新形势下城市道路平面交叉口红线规划存在的争议,首先明晰了交叉口红线规划和交通功能设计的关系。分析国内外城市在该领域的规范规定、实践、趋势及差异性。然后,从发展理念转型、设计工作转型、空间确定性与功能不确定性协调、政策机制保障等方面提出平面交叉口红线规划的基本原则。综合新发展理念要求和城市发展阶段特征,提出了基于道路网临界间距的交叉口红线展宽方法和区分功能类型的交叉口红线切角差异化方法。最后,从体制机制、思考方法、历史观等角度提出交叉口红线规划的若干思考。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.
