SOLUTION: The travel support device 10 includes a travel plan setting part 104 for calculating a traffic priority, and for supporting a travel of the vehicle, based on the calculated traffic priority, and the travel plan setting part 104 calculates the traffic priority, based on traffic conditions in the future of the plurality of vehicles predicted by a traffic situation predicting part 102. The traffic flow in the future of all the plurality of vehicles is thereby prevented from getting worse, compared with that when the traffic priority is determined by only right-turn waiting time or the like.
