集装箱港区集疏运路网脆弱性解析模型

A Vulnerability Analytical Model for Road Network in Container Port Area

随着港口吞吐量的不断增长,日益庞大的集疏运交通流量也给集疏运路网带来了一定的压力。准确判断港口发展对集疏港道路网络的脆弱性的影响是港口集疏运通道规划主要依据之一。为了研究港口发展对集疏运网络脆弱性的影响,选取一定的评价指标,构建解析模型,并以北方某新建港区为研究对象,基于仿真模拟2015、2020和2030年的港区交通量预测及路网中重要路段交通数据的调查结果,比对有无港区集疏运交通流量情况下集疏港道路网络的脆弱性结果,定量地分析了港区建设对周边城市主干道的脆弱性的影响程度及范围。

The port traffic flow will bring a certain amount of pressure to the port transport network with the development of the port enterprises.Accurately judging the impact of port development on the vulnerability of the port transport network is one of the main basis for the port traffic planning.Those results of port internal traffic simulation in 2015,2020 and 2030 as well as important roads’data in the road network through investigation from a new north Port Project were collected to build a Vulnerability Analytical Model for port transport network with some suitable parameters describing road network vulnerability,and find the comparison of road network vulnerability results with or without port traffic flow.And the extent and scope of the impact of the port construction on the vulnerability of those urban trunks were analyzed quantitatively.
