Abstract
Abstract A navigation system includes a CD-ROM for storing operational schedule data of transportation means operating along railroad, road and air routes contained in a map to be displayed on a screen of the system, and a display for reading the operational schedule data from the CD-ROM and displaying the read operational schedule data on the screen. By the addition of a few elements to a conventional navigation system, a navigation system with new functions and improved cost performance is obtained.
