PROBLEM TO BE SOLVED: To provide a travel route provision method with which it is possible to suppress the possibility of a route far apart from a user's scheduled travel angle being applied to a search route.SOLUTION: A travel link sequence is created in mesh units on the basis of probe information received from a vehicle 10, a first angle formed by a line linking the entry and exit points of a mesh and a reference line is found for the travel link sequence, and the travel link sequence is stored in a database 22 in association with a user, mesh, and first angle. When a route search request is received from the vehicle, a second angle formed by a line linking the entry and exit points of a mesh and a reference line is found for each mesh that a scheduled travel route set to the requesting vehicle passes through, and a travel link sequence with which is associated the first angle whose difference from the second angle is within a prescribed range is selected, for each mesh that the scheduled travel route passes through, from a travel link sequence stored in the database, present in the same mesh, and pertaining to a requesting user.SELECTED DRAWING: Figure 1
