奥体立交交通节点改造方案研究

奥体立交位于广东省奥林匹克体育中心附近，是广州东部重要的交通枢纽，东西向可联系广佛莞深，南北向可串连白云机场及广州东南片区，承担了广园快速路、车陂路、车陂路北延线、大观路等城市干道与环城高速及广州新白云国际机场第二高速公路的交通转换，方案对于广州东南片区的路网功能至关重要。从奥体立交现有交通功能出发，结合交通流量预测等对现状奥体立交进行提升改造，同时对重要节点进行方案比选，优化设计方案。

Study on Reconstruction Scheme of Traffic Node for Olympic Sports Interchange

The Olympic Sports interchange is located near the Olympic Sports Center of Guangdong Province. It is an important transportation hub in the east of Guangzhou. It can connect Guangzhou, Foshan, Dongguan and Shenzhen in the east-west direction, and connect Baiyun Airport and the southeast area of Guangzhou in the north-south direction. It is responsible for the traffic transformation of urban trunk roads such as Guangyuan Expressway, Chebe Road, the north extension of Chebe Road and Daguan Road, the ring expressway and the second expressway of Guangzhou New Baiyun International Airport. The scheme is very important for the road network function of the southeast area of Guangzhou. Based on the existing traffic function of the Olympic Sports Interchange and combined with the prediction of traffic flow, the existing interchange of Olympic Sports is upgraded and reconstructed. Also the schemes are compared and selected for the important nodes, and the design scheme is optimized.
