Abstract
Recently, the intelligent transportation system (ITS) that provides driver convenience and reduces the number of road casualties is in the spotlight. ITS must quickly deal with the emergency situation and provide information which drivers need. In ITS, a different channel will be assigned for each service to provide the service efficiently. However, if the channel is used at an emergency situation, the service cannot be provided immediately. For overcome this problem, we introduce the cognitive radio technology into ITS and propose a new spectrum sensing method in this paper.
