Surface transportation systems encounter strong demand for improved safety, reduced congestion and enhanced throughputs which lead to continuous innovation on vehicular technologies, while meeting the need for a sustainable energy future. Applying vehicular connectivity and automated vehicle technologies to deliver a smart mobility system in view of safety, throughputs and required conveniences, will interface a core activity of intelligent transportation system (ITS) strategic planning and implementation. So far, the power source transition to electrification, either battery- or fuel cell-based, has not been fully considered globally within the future ITS strategy. Consequently a strategy for the smart mobility has been developed to 2025 at the Korean national level, of which the core approaches are described in this paper. In addition to the review on various test-bed developments and implementations in Europe, the US, and Japan, the strategic planning on technology roadmap and test-bed application by identifying and prioritizing the future road transport demand are discussed, emphasizing vehicular connectivity and electrification.
