Work began on projects such as Electronic Route Guidance System (ERGS) and CACS in the United States and Japan respectively.
[5] Numerous subsequent projects have been implemented all over the world such as the Advanced Safety Vehicle (ASV) program,[6] CHAUFFEUR I and II,[7] FleetNet,[8] CarTALK 2000,[9] etc.
These acronyms differ from each other either in historical context, technology used, standard, or country (vehicle telematics, DSRC, WAVE,[17] VANET, IoV, 802.11p, ITS-G5,[18] V2X).
[20] Many organizations and governmental agencies are concerned with issuing standards and regulation for vehicular communication (ASTM, IEEE, ETSI, SAE, 3GPP, ARIB, TTC, TTA,[21] CCSA, ITU, 5GAA, ITS America, ERTICO, ITS Asia-Pacific[22]).
[25] A study from the American Automobile Association (AAA) concluded that car crashes cost the United States $300 billion per year.
The U.S. Department of Transportation states that 21,000 of the annual 43,000 road accident deaths in the US are caused by roadway departures and intersection-related incidents.
[30] Over the years, there have been considerable research and projects in this area, applying VANETs for a variety of applications, ranging from safety to navigation and law enforcement.
In December 2016, the US Department of Transportation proposed draft rules that would gradually make V2V communication capabilities to be mandatory for light-duty vehicles.
[32] V2V is under threat from cable television and other tech firms that want to take away a big chunk of the radio spectrum currently reserved for it and use those frequencies for high-speed internet service.
The Federal Communications Commission (FCC) has taken the side of the tech companies, with the National Transportation Safety Board supporting the position of the automotive industry.
[33] With governments in different locales supporting incompatible spectra for V2V communication, vehicle manufacturers may be discouraged from adopting the technology for some markets.
[34] The spectra reserved for V2V communications in some locales are as follows: In 2012, computer scientists at the University of Texas in Austin began developing smart intersections designed for automated cars.
[39] V2V equipped cars broadcast a message to following vehicles in the case of sudden braking to notify them timely of the potentially dangerous situation.
