Based on a report from WHO, about 1.25 million people die each year as a result of road traffic crashes, raising serious concerns among many countries. In an effort to reduce crashes and death rate, US Department of Transportation has proposed a rule in 2016 to mandate Vehicle-to-vehicle (V2V) technology included on 100% of new car production by 2021. This ruling will, as a result, accelerate the development of connected vehicles and the growth of intelligent transportation ecosystems, creating tremendous opportunities for related industries. The current development of communication technology has progressed beyond V2V communication to Vehicle-to- everything (V2X) communication. V2X is the technology that allows vehicles to communicate with practically any objects, which has led to the introduction of six other types of communication, including Vehicle-to-vehicle (V2V), Vehicle-to-roadside (V2R), Vehicle-to-infrastructure (V2I), Vehicle-to-pedestrian (V2P), Vehicle-to-motorcycle (V2M) and Vehicle-to-train (V2T). These technologies will work in collaboration to collect information from different entities and transfer these data to the backend for analysis to optimize traffic flow and improve driver safety. In addition, by adopting V2X, drivers will be able to receive early warning of road hazards, road work, heavy traffic and other issues, enabling a more convenient, more efficient, and safer transportation system.
Three major applications of V2X
Safety and congestion are the biggest problems on our roads today, and the primary function of V2X technology is to enhance driver safety and relieve traffic congestion. Currently there are 3 major applications of V2X technology: automatic warning, emergency calling, and traffic control, each of which is implemented to reduce accident numbers and improve driver experience.
Automatic warning
When vehicles and other entities become interconnected, they enable V2X technology to constantly receive signals from the surrounding using on board unit (OBU), road side unit (RSU), and sensors, then pass along these real-time messages to the driver regrading road conditions, traffic flows and obstacles. When a potential danger is detected, be it sudden lane changing, forward collision, or unexpected pedestrian, V2X will automatically alert the driver in advance to allow quicker response time for preventing accidents.
Emergency calling
In 2015, the European Parliament voted to require all new cars be equipped with eCall (emergency call system) system starting from March 2018. In the event of a serious accident, this in-vehicle system will automatically dial 112 (the European emergency number) and send information of its exact crash location, incident time, vehicle identification and whether the alert was triggered automatically or manually to the emergency services, reducing the time between when the crash occurs and when medical services are provided, which consequently minimize the rate of death and disability. Although only 3% of vehicles have installed this system, we can expect more government will in favor of this deployment to save lives.
Traffic control
Traffic congestion is a daily problem faced by drivers, causing tremendous loss economically and socially. There are many factors contributing to traffic jams, but some of the common ones are road work, inadequate signal timing, unnecessarily long following distance and accidents, all of which can be minimized with the support of V2X technology. When cars are able to communicate with other vehicles, traffic lights and road infrastructure, they know what speed they should travel in to make the green light; what route to take when there’s road work ahead; what distance to keep from other vehicle to avoid car accidents while ensuring smooth traffic flow, making V2X communications the promising solution to this worsening problem.
