针对因城市特殊环境的制约导致一些实用的立交类型受到限制的问题,提出“兑”字形城市十字路口立交模型,通过减少车流危险点、完善交通功能来保障非机动车和行人的通行利益,弥补其他立交的部分不足;运用层次分析法,从互通性、通行能力、经济性和美观性方面与5种城市常见立交比较,综合分析得出“兑”字形立交适用于城市快速路、主干路之间相交的十字路口且存在较大流量的非机动车和行人的交通环境。
Aiming at the problem that some practical types of interchanges are restricted due to the restriction of the special urban environment, this paper proposes a crossroad intersection model of “Xinyu” shaped city, and protects the non-motorized vehicles and pedestrians’ interests by reducing the dangerous points of traffic flow and improving traffic functions , Make up for the lack of other parts of the interchange; Analytic Hierarchy Process, from the interoperability, accessibility, economy and aesthetics compared with the five kinds of cities common interchange, a comprehensive analysis of the “to” glyphs applied to the city expressway , The intersection of the main road at the intersection and there is a larger flow of non-motor vehicles and pedestrian traffic environment.
