PROBLEM TO BE SOLVED: To provide an onboard system and operation support method in which a user is able to recognize the evaluation value of the degree of low environment burden in relation with the gradient of cruising road. SOLUTION: The vertical axis of an evaluation point graph 502 is considered as evaluation point, and horizontal axis of the same serves as route distance. The vertical axis of an altitude graph 501 serves as altitude, and the horizontal axis is made to serve as route distance. The horizontal axis of the evaluation point graph 502 and the altitude graph 501 are made as one horizontal axis common. The origin of the horizontal axis concerned is set on the center of the horizontal axis. The area on the left of the origin of horizontal axis i.e. the area of the route distance is negative; a line graph showing the altitude of every spot travelled in the past is drawn as the altitude graph 501, and a bar graph showing evaluation point computed at every spot travelled in the past is drawn as the evaluation point graph 502.
