Research Abstract	Information on freeway congestion has many advantages for drivers because it can not only decrease driver's irritation but also give them the valuable information in order to select the best route for themselves, on a highway or freeway. On the other hand, it is also criticized that the current definition used by freeway information has discrepancy to drivers' consciousness of congestion. We studied the discrepancy between them according to a questionaire of congestion consciousness of freeway drivers. And we proposeda definition of freeway congestion on the basis of drivers' consciousness. We also verified the propriety of this definition by comparing with the experiment on drivers' consciousness under the real driving situation. Furthermore the congestion definition is improved by using a fuzzy reasoning.
