城市路网复杂节点的“组合-层次”设计方法

摘要:

复杂交通节点是制约城市路网通行能力和服务水平发挥的瓶颈。为在系统层面提高其运行水平,本文探讨了针对复杂节点的“组合-层次”设计方法。首先,对复杂节点包含的交通转换关系进行了分析和定义；其次,对“组合-层次”分析的思路进行了具体的阐述；最后,以惠州四环东路为例,应用“组合-层次”方法对涵盖高速公路、快速路、主干路等多种道路类型的复杂节点进行了应用设计,验证了该方法的可操作性。

Abstract:

Complex traffic node is the bottleneck of restricting the capacity and service level of urban road network. In order to improve its operation level at the system level, this paper discusses the "combination-hierarchy" design method for complex nodes. Firstly, it analyzes and defines the traffic conversion relationship contained in complex nodes; secondly, it elaborates the idea of "combination-hierarchy" analysis; finally, Taking Huizhou Fourth Ring East Road as an example, it applies the "combination-hierarchy" method to design complex nodes covering highway, expressway, trunk road and other road types, and verifies the effectiveness of the method Operability.
