A navigation system (12) comprising a required time calculator (39) for calculating a virtual required time period when a first movable body (11) is assumed to travel a second route (111) different from a first route (112) the first movable body (11) actually travels and arrive at a second point (120). The system (12) comprises a storage section (22) for storing movement characteristics of the first and second movable bodies, said characteristics including vehicle static information (26), vehicle dynamic information (27) and user information (28). The required time calculator (39) preferentially acquires position information (55) from a second movable body (110) travelling on the second route (111) and having information (25) indicating a movement characteristic similar to information (25) indicating the movement characteristic of the first movable body (11) from among one or more of second movable bodies (110). The required time calculator (39) calculates the virtual required time period using the acquired position information (55).
