大型复合型多路交叉口总体设计及交通组织

On General Design & Traffic Organization of Large-scale Complex Multiple Roads Intersections

多路交叉口通常由环形交叉口来组织交通。随着交通量的迅猛增长,多路交叉口成为城市交通瓶颈,探讨多路交叉口的改善方案十分必要。随着城市轨道交通的建设,多路交叉口往往成为含机动车交通、公共交通、慢行交通的复合型交叉口。通过对多路交叉口的问题分析,提出区域改善和节点改善相结合的解决思路,进而提出具体改善措施,并通过武汉鲁巷广场的实际交叉口案例进行论证。

Traffic of multiple roads intersections is usually organized by circle intersections.With the rapid growth of traffic flow,multiple roads intersections have become the urban traffic bottleneck,so it is necessary to discuss the improvement plan of multiple roads intersections.And with the construction of urban transit rail traffic,multiple roads intersections will become the complex one containing motor vehicle,public traffic and non-motorized traffic.Through the problem analysis of multiple roads intersections,the solution idea of the combination of regional improvement and node improvement is proposed,and moreover,the detailed improvement measures are put forward.Finally,the practical intersections case of Wuhan Lugang Square is discussed.
