Siemens is to supply the complete solution, including hardware and software plus numerous subsystems to facilitate a safe and efficient flow of traffic in the tunnel. The centerpiece will be the International Tunnel Control Center (ITCC), which will use Simatic WinCC open architecture for the operations control system. The ITCC will draw on real-time data to assess conditions in the tunnel and decide on actions to optimize traffic flow taking account of all pertinent safety aspects. Automated incident and congestion detection, emergency management for accidents, tunnel closure and contraflow management are just some of the main functions provided by the ITCC.
The Southern Chinese city of Shenzhen intends to create six separate links with the Hong Kong special administrative region to improve transport integration between the two. The six link projects planned (the Liantang road link, the Longhua railroad link, the Guangzhou-Shenzhen-Hong Kong passenger rail link in Fujian, Dachan Gulf Harbor, the Nan'an tourist link and a sub-sea tunnel connecting the airports of Shenzhen and Hong Kong) will connect Shenzhen and Hong Kong by road, rail and sea.
