Summary:

To explore the comparison and optimization of cross sections for six lane traffic organization in the digital design conditions of expressway reconstruction and expansion, a systematic analysis was conducted on the selection and different combinations of cross section layout parameters for bidirectional six lane traffic protection schemes during the construction period based on the Guangzhou Shenzhen Expressway reconstruction and expansion project. A simulation model based on real traffic flow was constructed, and a recommended cross section layout scheme for six lane traffic protection schemes during expressway reconstruction and expansion construction based on traffic safety and traffic efficiency was proposed. The comprehensive ranking of cross section parameter importance was given. The results showed that in terms of comprehensive importance priority, the right lateral clearance width>right lane width>left lateral clearance width>middle lane width>left lane width can provide reference for the optimization of cross section layout for six lane traffic protection schemes in expressway reconstruction and expansion projects
