Abstract: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.
