a radio beacon is connected to a brake light. In fall 2008, network ideas were tested in Europe, where radio frequency bandwidth had been allocated. The 30 MHz allocated is at 5.9 GHz, and unallocated bandwidth at 5.4 GHz may also be used. The standard is IEEE 802.11p, a low-latency form of the Wi-Fi local area network standard. Similar efforts are underway in Japan and the USA. Emergency warning system for vehicles Telematics technologies are self-orientating open network architecture structures of variable programmable intelligent beacons developed for application in the development of intelligent vehicles with the intent to accord (blend or mesh) warning information with surrounding vehicles in the vicinity of travel, intra-vehicle, and infrastructure. Emergency warning systems for vehicle telematics are developed particularly for international harmonization and standardization of vehicle-to-vehicle, infrastructure-to-vehicle, and vehicle-to-infrastructure real-time Dedicated Short-Range Communication (DSRC) systems. Telematics most commonly relate to computerized systems that update information at the same rate they receive data, enabling them to direct or control a process such as an instantaneous autonomous warning notification in a remote machine or group of machines. In the use of telematics relating to intelligent vehicle technologies, instantaneous direction travel cognizance of a vehicle may be transmitted in real-time to surrounding vehicles traveling in the local area of vehicles equipped (with EWSV) to receive said warning signals of danger. Intelligent vehicle technologies Telematics comprise electronic, electromechanical, and electromagnetic devices—usually silicon micro-machined components operating in conjunction with computer-controlled devices and radio transceivers to provide precision repeatability functions (such as in robotics artificial intelligence systems) emergency warning validation performance reconstruction. Intelligent vehicle technologies commonly apply to car safety systems and self-contained autonomous electromechanical sensors generating warnings that can be transmitted within a specified targeted area of interest, i.e. within 100 meters of the emergency warning system for the vehicle's transceiver. In ground applications, intelligent vehicle technologies are utilized for safety and commercial communications between vehicles or between a vehicle and a sensor along the road. On November 3, 2009, the most advanced Intelligent Vehicle concept car was demonstrated in New York City when a 2010 Toyota Prius became the first LTE connected car. The demonstration was provided by the NG Connect project, a collaboration of automotive telematic technologies designed to exploit in-car 4G wireless network connectivity. Carsharing Telematics technology has enabled the emergence of carsharing services such as Local Motion, Uber, Lyft, Car2Go, Zipcar worldwide, or City Car Club
