大规模环形交叉口的慢行交通解决方案

A Slow Movement Solution for Large-scale Roundabout

为优化武汉光谷广场环形交叉口的慢行交通,对光谷广场综合体改造项目的优化方案进行分析。以城市大规模市政设施建设为契机,结合城市轨道交通线路和市政隧道的建设,对该交叉口的慢行交通进行了多层立体的交通设计。结果显示,光谷广场综合体的改造缩短了该环形交叉口的行人过街距离和过街时间,避免了该交叉口的机非混行,但是增加了非机动车的绕行距离,且局部存在人非冲突节点,需要通过一定的管理措施来规范慢行交通行为。

The paper analyzes the optimal design scheme of Guanggu square complex in Wuhan in order to optimize the slow movement at roundabout the square.Taking the large-scale municipal facilities construction as an opportunity,combining the construction of urban rail transit lines with municipal tunnels,the multilayer design of the slow movement at the intersection is carried out.The outcome shows that the renovation of Guanggu square complex shorten pedestrian crossing distance and crossing time of the roundabout,avoiding the mixed traffic between motor vehicles and non-motor vehicles,but increasing the circumnavigation distance of non-motor vehicles,and conflict nodes between pedestrians is existed between pedestrians and non-motor vehicles.All these problems is required certain management measures to regulate slow movement behavior.
