快速化公路与市政道路互通方案研究

Study on Interchange Scheme Between Fast Highway and Municipal Road

伴随着城市路网的规划布局,城镇化地区的高等级公路往往兼顾着城市快速干道的功能,同时,城市快速的发展,交通量势必迅速增长,交通设施建设跟不上交通量的增长速度,造成严重的城市交通拥堵问题,路网交叉节点拥堵问题尤为突出。结合城市路网分布密集,交叉节点众多的特点,对快速化公路与城市主干路的立体交叉方案设计提出更高的要求。以佛山塘西大道的广海立交为实例,充分考虑立交周边环境影响、交通功能需求及交通主要流向等因素,系统地阐述了立交方案优化过程,提出了立交总体方案设计的新思路。

With the planning and layout of urban road network,high-grade roads in urbanized areas often take into account the functions of urban expressway.At the same time,with the rapid development of the city,the traffic volume is bound to grow rapidly,and the construction of traffic facilities can not keep up with the growth rate of traffic volume,resulting in serious urban traffic congestion,especially at the intersection of road network.Combined with the characteristics of dense distribution of urban road network and many intersection nodes,higher requirements are put forward for the interchange scheme design of expressway and urban trunk road.Taking Guanghai interchange of Tangxi Avenue in Foshan as an example,fully considering the factors such as the impact of the surrounding environment,traffic function demand and main traffic flow direction of the interchange,this paper systematically expounds the optimization process of the interchange scheme,and puts forward a new idea of the overall scheme design of the interchange.
