| 中文摘要: |
| 在城市高架桥的建设中，桥下的平面交叉口空间受高架桥体的影响，很多属于宽中央隔离带的路口，两个路口中间部分按照路段进行渠化，车流互相影响严重。为了解决这类问题，以石家庄市北二环和红星街的平面交叉口为例，对宽中央隔离带路口的交通组织进行了研究。主要从路口渠化和配时上提出了新的交通组织方案，最后利用VISSIM仿真软件对方案进行评价。仿真结果表明：提出的新方案可有效减少延误，提高交叉口运行效率。 |

| At present, due to the construction of viaduct, the intersection space under the bridge is affected. Many intersections with wide center isolation area are channelized at the central part of the intersections, and traffic flows seriously affect each other. In order to solve this problem, taking the intersection of Beierhuan and Hongxing Street in Shijiazhuang as an example, this paper studies traffic organization for intersections with wide center isolation area. Based on the research of traditional channelization and signal control, a new method wis put forward. Finally, Vissim software is used to make simulation of the new method. The simulation results show that the new method may decrease delay and improve the operation efficiency at intersection. |
