ABSTRACT:
A road map is provided which allows a determination to be intuitively rendered whether a course contains an increased number of upward slopes or downward slopes as viewed in the direction of the course. The direction of the course is set up across roads indicated on the map, and the upward slopes and the downward slopes located along the course are indicated in different colors. For example, the direction of the course is set up on the map by a starting point and destinations. A gentle upward slope is indicated by a red color of a low thickness, a medium upward slope is indicated by a red color of a medium thickness and a sharp upward slope is indicated by a red color of a high thickness. On the other hand, a gentle downward slope is indicated by a blue color of a low thickness, a medium downward slope is indicated by a blue color of a medium thickness and a sharp downward slope is indicated by a blue color of a high thickness. Accordingly, a determination as to whether the course contains an increased number of upward slopes or downward slopes can be intuitively made.
