Automotive industry is moving towards V2X technology which basically allows vehicles to communicate with each others and every device on the road at a particular time and place and shares information between each other while on the road. It is expected that at the end of the day, it will improve efficiency and safety of all the road users. V2X technology includes V2V (Vehicle to Vehicle), V2I (Vehicle to Infrastructure) and V2P (Vehicle to Pedestrian).
General Motor will be the first automaker which will bring this technology to the market with its 2017 Cadillac CTS. However, before the technology can work as per intended it to be, an infrastructure need to be built. Apart from Europe and United States, China is the next location that the automaker is planning to promote the technology.
Before building a complete V2X technology, General Motor is promoting the adoption of dedicated short range communications (DSRC) in China as a start. According to Dr Hariharan Krishnan, GM Global R&D Electrical and Controls Research Technical Fellow, in his recent visit to Shanghai, to move toward the world of V2X, it is essential for China to allocate the spectrum for intelligent connected vehicles. He added that leveraging the development of connected vehicle systems based on DSRC in other markets would save time and money in China.
DSRC technology dedicated spectrum was already allocated by United States Federal Communications Commission (FC) in 1999. It aims to provide advantage such as fast network acquisition, low latency and high reliability, priority for safety applications, interoperability, security and privacy. The mature DSRC standard has been developed in the United States and Europe. If it is used together with GPS, DSRC is able to accurately determine the location and movement of other vehicles within 300 meters range.
