<p>Provided is a route through which a user can smoothly travel and on which an evaluation of traveling environment is reflected. A route search system includes a user input receiving unit (13, 7517) which uses a delay time from an expected travel time as an index indicating comfort of a route and selects a factor such as traffic conditions and pedestrians set as a condition that a user desires avoidance, a delay time calculation unit (16, 715) which calculates a delay time from an expected arrival prediction time according to map information, traffic information, and traveling environment information so as to reduce a delay as far as possible due to the selected factor, and calculates a cost based on the delay time, and a route search unit (15, 7516) which calculates a cost of a link used for a route search from the delay time, and searches a route by using the calculated cost.</p> |
