城市中心的环形交叉口,由于受行人的巨大影响,经常成为城市交通的瓶颈。从减小行人对环形交叉口的影响出发,以承德市火神庙交叉口为实例,设计两种改造方案,以增加交叉口通行能力,并通过对比两种方案,确定最佳改建方案,可供类似改造工程借鉴。
Because of the tremendous impact of the pedestrian, roundabouts often become urban traffic bottlenecks. Taking reducing the impact of pedestrian on the roundabout as a target, and taking Huoshenmiao roundabout in Chengde City as an example, two rehabilitation programs are designed to increase intersection's traffic capacity. The two programs are compared in order to determine the best reconstruction program. The practice can be consulted by similar reconstruction engineering.
