PROBLEM TO BE SOLVED: To provide a vehicle support device for calculating an angle to an advancing direction of a vehicle and improving the accuracy of evaluating the position of the vehicle by using an optical beacon device for vehicle position evaluation. SOLUTION: In the vehicle support device, a light receiving means 2 receives a plurality of diffusion light beams from a light emitting means 1 of a roadside device, an optical information detecting means 3 detects the amount of the received light, an optical information storing means 4 stores the amount of light, a variation operating means 5 operates a variation of the amount of light, a traveling direction predicting means 7 predicts a traveling direction of the vehicle on the basis of a traveling speed measured by a traveling speed measuring means 6 and the variation, and a display means 8 displays the prediction result. The vehicle support device can achieve the stability and high accuracy of evaluating the vehicle position by calculating a traveling angle of the vehicle by the variation of the diffusion light beams from the light emitting means 1 and predicting the traveling direction.
