Building an intelligent route guidance system is increasing important to ease traffic congestion pressure in fast growing cities, as a result of the urbanization trend. In another aspect, the network infrastructures promoted by the ideology of digital city reinforce the Intelligent Transportation Systems (ITS), which provides innovative resolutions to the challenge. As traditional centralized dynamic route guidance systems are becoming incapable of coping with these challenges, because of computational complexity and fast growing traffic big data, this paper proposes how to apply the MapReduce approach, the kernel approach in cloud computing, to construct a novel decentralized dynamic route guidance system (DDRGS). By distributed computing architecture, DDRGS is able to effectively reduce the overall data processing time, require less information from drivers, achieve more effective communication, and provide more accurate real-time route recommendations and push notification service.
