According to World Health Organization (WHO), approximately 1.35 million people die each year as a result of road traffic crashes, and between 20 and 50 million more people suffer non-fatal injuries, with many incurring a disability as a result of their injury.Nearly all car crashes are due to human errors. It is estimated by the US Department of Transportation (DOT) that 94% of the fatal crashes, which are caused by human errors, can be avoided if fully autonomous vehicles are taken.
In addition with camera, radar and LIDAR, a fully autonomous vehicle (AV) normally will be equipped with V2X on-board unit, which broadens vehicle’s view to the Non-Light-of-Sight (NLOS) area. It is very stable and reliable regardless of adverse weather condition. By receiving and sharing real-time driving status with infrastructures and other vehicles in proximity, the AV is able to see through the objects, take bends safely, and predict the road conditions. The US National Highway Traffic Safety Administration (NHTSA) stated that V2V/V2I could eliminate or reduce the severity of up to 80 percent of non-impaired-driving crashes, saving millions of lives.
V2X is the connectivity foundation of autonomous driving. Each vehicle with V2X installed is a network node that links with other traffic elements, such as traffic lights, pedestrians and cyclists, to form a shared traffic network. It is believed that the commercial deployment of V2X and maturity of autonomous driving in the near future will significantly reduce traffic accidents and save people’s lives.
