V2V Vehicle Safety Communication

Shrivastava, Shubham

Abstract National Highway Traffic Safety Administration (NTHSA) has been interested in vehicle-to-vehicle (V2V) communication as the next step in addressing grooving rates of fatalities from vehicle related crashes. Today’s crash avoidance technologies depend on on-board sensors like camera and radar to provide awareness input to the safety applications. These applications warn the driver of imminent danger or sometimes even act on the driver’s behalf. However, even technologies like those cannot “predict” a crash that might happen because of a vehicle which is not very close or not in the line of sight to the host vehicle. A technology that can “see” through another vehicle or obstacles like buildings and predict a danger can fill these gaps and reduce crashes drastically. V2V communications can provide vehicles the ability to talk to each other and therefore see around corners and through the obstacles over a longer distance compared to the current on-board sensors. It is estimated that V2X communications address up to 80% of the unimpaired crashes [1]. By means of Notice of Proposed Rulemaking (NPRM), NHTSA is working towards standardization of V2V communications and potentially mandating the broadcast of vehicle data (e.g. GPS coordinates, speed, acceleration) over DSRC through V2V.
