Intelligent Transport Systems (ITS) have been developed rapidly all over the world. All the information in vehicles/high-speed trains, roads and the surrounding environments is collected and communicated among vehicles/ high-speed trains and humans. Moreover, huge amount of data is stored, computed and processed in the common platform, by which the system can effectively reduce the road accidents, improve the traffic management, and enable people to enjoy mobile Internet application services.

On the way to implement ITS in our real life, many challenges have to be conquered. First of all, it is essential to provide efficient, reliable and in time communications to all vehicles/trains and their embedded sensors. Thanks to the emerging new technologies in the fifth generation (5G) mobile communication networks, feasible solutions, e.g., new signal processing schemes, cloud computing, network virtualization, and so on, can be provided to meet various requirements of ITS services. Empowered with the advanced 5G communications capabilities, it is expected that future ITS can well support the functions of sensing, networking, computing and controlling. Thus, it can greatly improve the efficiencies in transportation infrastructures while reducing the traffic congestions, emergencies and accident. Moreover, the processing and storage technologies of big data in future ITS become very important with the massive number of vehicles/trains connected by 5G networks. All these issues are being studied in academics, industries, and standardization organizations.
