摘　　要：交叉口是城市道路的重要组成部分,城市路网体系的咽喉和城市交通大动脉畅通的关键节点,故交叉口的选型至关重要。由于我国早期城市规划理念落后、城市发展不均衡、居民汽车拥有量逐步攀升及交叉口选型不合理等因素,交通拥堵已成为各城市日益突出的民生问题。以丰城市龙光大道人民医院环形交叉口优化方案为例,以问题为导向,形成多方案比选,最后选择合理的交叉口改造方式,以解决城市的交通安全和交通拥堵问题。Intersection is an important part of urban roads,the throat of urban road network system and the key node of urban traffic arteries.Therefore,the type selection of intersection is crucial.Due to the backward concept of early urban planning,the uneven urban development,the gradual increase in household car ownership and the unreasonable selection of intersections in China,the traffic congestion has become an increasingly prominent livelihood problem in various cities.Taking the rotary intersection optimization scheme of Longguang Avenue People's Hospital in Fengcheng City as an example,many schemes are compared by the problem-oriented,and finally a reasonable reconstruction mode of intersection is selected to solve the traffic safety and traffic congestion in the city.
