摘　　要：城市互通立交的研究起源于城市交通发展和规划需求,随着城市化和交通流量的增加,互通立交作为一种高效的立体化道路交叉方式,能够优化交叉流分布,提高道路通行能力。在具体的设计中,文章提到了互通立交位置选择、选型、视距问题、出入口线型指标问题、通过对这些问题的全面讨论,文章强调了设计者在城市互通立交规划和建设中需要关注的关键因素,以确保其在不同条件下都能够实现高效、安全、环保的交通系统。The study of urban interchanges originates from the development and planning needs of urban transportation.With the increase in urbanization and traffic volume,interchanges,as an efficient three-dimensional road intersection method,can optimize the distribution of traffic flows and enhance road capacity.In the specific design,this paper discusses the selection of interchange locations,types,sight distance issues,and entrance/exit alignment indicators.Through a comprehensive discussion of these issues,the paper emphasizes the key factors that designers need to focus on in the planning and construction of urban interchanges to ensure the realization of an efficient,safe,and environmentally friendly transportation system under various conditions.
