1. A vehicle traveling control device comprising:
a communication unit configured to carry out vehicle-vehicle communication with preceding vehicles;
a position information acquisition unit configured to acquire position information on the preceding vehicles and following vehicles around a host vehicle, the host vehicle being able to carry out vehicle-vehicle communication with the preceding vehicles;
a number of vehicles calculation unit configured to calculate a reference number of vehicles and an estimated number of vehicles based on the position information acquired by the position information acquisition unit and a communication range of the communication unit, the reference number of vehicles being a number of the preceding vehicles with which the host vehicle can carry out vehicle-vehicle communication, the estimated number of vehicles being a number of the preceding vehicles with which the host vehicle can carry out vehicle-vehicle communication, the estimated number of vehicles being a number of the preceding vehicles determined using the assumption that the host vehicle will travel at a traveling position behind each of the following vehicles; and
a traveling control unit configured to cause the host vehicle to travel at the traveling position behind the following vehicle if the estimated number of vehicles is larger than the reference number of vehicles.
