Systems, methods, and computer-readable media are directed to increasing the accuracy of vehicle positioning. Example methods may include transmitting, by an on-board unit, a message including a motion information associated with the vehicle; determining, by a processor, a signal comprising modulating radiation, the signal identifying the vehicle; receiving, by the on-board unit, an additional message, the additional message including location information and a timestamp; and determining a location of the vehicle based on the location information.
