摘要
广佛高速公路沙贝互通立交是全省高速公路网的重要枢纽互通,近年来,随着交通量日趋饱和,该立交及周边路网拥堵已成常态化。从广佛高速公路沿线及城区发展变化着手,利用Transcad工具的关键路段分析模块,探究了该路段的主要交通流成分,从交通流量、区域路网、广佛同城化、周边产业分布等方面分析了该互通的拥堵原因,提出采用近远结合的策略及其相应的整治措施,并利用省域交通需求预测模型对整治方案进行评估分析,为下阶段区域高速公路网优化和沙贝互通立交的拥堵整治提供依据和参考。
The Shabei Interchange of Guang-Fo Expressway is one of the most important highway network hub interchanges in Guangdong Province. In recent years,with the increasingly saturated volume of traffic,congestion at the interchange and the surrounding road network has become normalization. Based on analyzing development of surrounding urban areas of Guangfo Expressway,in this paper,the main sections of the traffic flow have been explored using the key sections of TransCAD tools. From traffic flow,the regional road network,Guangzhou-Foshan Urban Areas Connected and the surrounding industrial distribution and other aspects of the causes,it has been proposed to use far and near combination strategy,the corresponding remediation measures,which could be evaluated by provincial traffic demand forecasting model,which could provide a basis and reference for the optimization of highway network in the future.
