A mobility information provision system includes a collector, a mapping unit, a generator, and a controller. The collector collects field information on movement of mobile bodies using communication apparatuses provided in respective predetermined zones or respective predetermined sections. The mapping unit maps positions of the mobile bodies based on the collected field information. The generator generates course-related information based on information on the mapped positions of the mobile bodies. The controller is provided for each of the mobile bodies and controls movement of corresponding one of the mobile bodies based on the course-related information. If the collected field information includes information on an obstacle that would hinder the movement of the mobile bodies, the mapping unit maps the obstacle together with the positions of the mobile bodies, and the generator generates the course-related information for the mobile bodies to cause the mobile bodies to move avoiding the obstacle.
