A vehicle presence detection system for effectively detecting the presence of a vehicle in a location based upon a measured radio wave signal strength by a receiver. The vehicle presence detection system generally includes a main receiver adapted for receiving a radio wave signal from a transmitter and a control unit in communication with the main receiver that determines a signal strength of the radio wave signal received by the main receiver. The control unit determines that a vehicle is near the transmitter or the main receiver when the signal strength of the radio wave signal is reduced by a threshold loss.
