【摘要】 以珠江三角洲为例,分析了城市群区域交通特征、交通空间分布特征等;基于交通区位论和经济引力模型,确定了珠江三角洲城市群连接道路交通网络框架;以功能为核心,将城市群连接道路功能划分为通道功能、干线功能、集散功能和服务地方功能4个层次;进行了功能分级,划分为高速公路、城市群连接道路I级、城市群连接道路II级、城市群连接道路Ⅲ级、地方道路5个等级,建立了城市群连接道路功能分级体系。更多还原

【Abstract】 Taking Pearl River Delta as an example,the region traffic characteristics and traffic spatial characteristics of urban agglomeration are analyzed.Based on traffic location theory and economic gravity model,the framework of traffic net has been established.The functions of connection road of urban agglomeration are categorized,including channel function,arterial function,collector function and local service function.Furthermore,the classification system with five levels is developed,that is expressway,class I,II,III of connection road of urban agglomeration and local road.更多还原
