A vehicle guidance system includes an onboard apparatus and a ground apparatus. The onboard apparatus includes a guide controller guiding a vehicle to enter a predetermined area through an entrance, a transmission controller transmitting a first wave, and a reception controller receiving a second wave obtained in response to the first wave. The ground apparatus includes a plurality of ground receivers arranged at a first position and a second position to receive the first wave, the first position and the second position corresponding to opposed ends of the entrance, and a plurality of first ground transmitters provided corresponding to the ground receivers and transmitting the second wave in a direction opposite to an entry direction of the vehicle. The guide controller determines an entry line to the entrance based on a change of a signal level of the second wave, the signal level changing depending on a vehicle position.
