Now complete, the transport links are being run via an intelligent management system which utilizes big data, cloud computing and the internet of things to ensure maximum safety and efficiency.

For example, signage on the highway illuminates automatically in low light and on rainy or foggy days. A dynamic speed limit control system signals drivers to adjust their speed according to safety requirements.

Materials with ice and snow melting properties used in the tarmac, and automatic salt sprinkling devices prevent road surfaces from becoming frozen and slippery.

At tolls, drivers can pass without stopping with payment being facilitated by smart cameras, which scan license plates and deduct the toll from a linked account automatically.

A central traffic management control room acts as the beating heart of the whole operation. There is real-time traffic monitoring, big data-based intelligent analysis to monitor road conditions and predict possible problems.

This immense transport infrastructure has been put in place to serve another massive transport infrastructure project: Beijing Da xing International Airport.

Earlier this week, four commercial passenger planes completed flight trials at what is to become a new transportation hub for China to connect with the rest of the world.
