Abstract:
An embodiment provides a traffic information generating method for generating traffic information about a road on which a vehicle travels. A vehicle speed is detected by a vehicle speed sensor at predetermined distance or time intervals. By referring to a prescribed speed, a prescribed distance, and a link determination distance, a congestion degree associated with the vehicle speed is detected.
