立交匝道设计探讨

Discussion on Design of Interchange Ramp

随着人们生活节奏的加快,城市机动车的增长,造成了大量的交通拥堵现象。据有关调查数据显示,在交通叉路口处交通拥堵现象是极为普遍的,尤其是在上下班高峰时期。为此,修建立交桥成了必要的解决手段。论述设计立交桥过程中常被设计人员忽视的技术问题,即如何协调立交匝道加、减速与行程关系,并使之井然有序。这些问题对立交桥的技术指标、运行安全性、交通功能的发挥有着非常重要的影响。

At present, with the faster pace of life in city, the number of urban motor vehicle is increasing,which causes the traffic congestion and brings the great inconvenience for the trip of the people in city. Based on the data investigation, the traffic congestion is more general at the intersections of traffic, especially in the peak hours. Therefore, the construction of interchanges becomes the necessary solving means. The article discusses the technical problems often ignored by the designers in the process of interchange design. These problems how to coordinate the relationship between interchange ramp acceleration, deceleration and stroke and how to make in order has the very important influence on the technical index, operation safety and traffic function of interchange.
