摘　　要：建设快速路是城市拉开发展框架、扩充道路容量以及缓解交通拥堵的重要手段。结合石家庄市快速路网的规划和建设经验,分析快速路在中心城区段的复合型功能定位,应考虑兼顾道路扩容、应急救援通道、主干路标准提升等多种功能,快速路出入口应结合横向主干道路尽可能选择在路口设置,并应结合城市发展规模、路网密度等全面衡量出入口设置间距。以期能为后续有关城市研究快速路网的规划设计提供一些有益参考。The construction of urban expressway is an important means for cities to widen the development framework, expand the road capacity and alleviate the traffic congestion. In the light of the planning and construction experience of the urban expressway network in Shijiazhuang, the composite functional orientation of expressways in the central urban areas is analyzed. By considering the multiple functions of road capacity expansion, emergency rescue access and standard upgrading of arterial roads, the expressway accesses should be combined with the transverse arterial roads and set up at intersections whenever possible. The distance to set up the expressway accesses should be comprehensively measured in combination with the development scale and road network density of a city in order to provide some beneficial reference for the study on the planning and design of urban expressway network in the future.
