Abstract
A navigation system including a navigation roadway, which is simple in construction and thus cost-effective, ensures a vehicle to navigate even where a roadway curves, branches out, or merges with another. This navigation system comprises a mark-tracking navigator and a map-referring navigator. The mark-tracking navigator navigates the vehicle along a navigation-guiding mark on the roadway by detecting the navigation-guiding mark, and the map-referring navigator navigates the vehicle along a predetermined track on a route map of data by referring to the position of the vehicle which is detected by position-detecting means. The system selects either the mark-tracking navigator or the map-referring navigator to navigate the vehicle in correspondence with the condition of the roadway. The sections where the roadway extends straight or curves gradually are provided with the navigation-guiding mark, and the sections where the roadway branches out or merges with another or curves sharply are not provided with the navigation-guiding mark.
