A road is an open way for the passage of vehicles. Major roads include Interstate routes, U.S. routes, State routes, and other large roads.

Navigation system

A service-area road that is a road in a service area such as a rest area or parking area of an expressway is determined to be a road on which a vehicle travels on when the following three conditions are satisfied. A first condition is satisfied when the vehicle travels in an expressway. A second condition is satisfied when a main road of the expressway and the service-area road are designated as candidate roads in map matching process. A third condition is satisfied when a difference between the heading direction of the vehicle and the traffic direction of the main road is equal to or greater than a predetermined value. Thus, it can be as promptly as possible determined that the vehicle is traveling on the service-area road, allowing the vehicle mark to be accurately displayed on the service-area road on the displayed map.
