城市道路平面交叉口渠化设计——重庆市北部新区示范路口建设

Plane Intersection Channeling Design of Urban Road——Model Intersection Construction of Chongqing Northern New Area

城市道路平面交叉口是城市交通中的瓶颈,而交叉口的渠化设计是提高交叉口通行能力的重要方法。该文针对城市平面交叉口渠化设计特点,对城市平面交叉口渠化设计原则、基本方法和步骤进行了探讨。并结合重庆市北部新区示范路口建设,针对财富中心交叉口进行了案例分析。财富中心交叉口渠化改造,有效地改善了该交叉口交通状况、交通安全和城市景观。

The plane intersection of urban road is the bottle- neck of city traffic, but the channeling design of intersection is the important method of enhancing the traffic capability of intersection. According to the characteristics of urban plane intersection channeling design, this paper discusses the design principles, basic methods and procedure of urban plane intersection channeling. Combined with the model intersection construction of Chongqing Northern New Area and taking the intersection of Asset Center as an example, this paper carries out the example analysis. The intersection channeling reconstruction of Asset Center effectively improves the traffic condition, traffic safety and urban landscape of Asset Center Intersection.
