The US Department of Transportation's ITS Joint Program Office has issued a Request for Information for its next five-year plan, which will emphasis the transformative potential of wireless connectivity. Shelley Row, ITS JPO Director, writes. During his confirmation hearing in January, US Transportation Secretary Ray LaHood emphasised that the US Department of Transportation (USDOT) will remain committed to improving the safety of the country's transportation system under his leadership, and will engage in
The connected car concept is predicated on fast and reliable wireless communications in all locations but research has revealed wide variations in connectivity. The performance of wireless communications between two vehicles (V2V) or a vehicle and the infrastructure (V2I) is highly dependent on the environment and any surrounding interacting objects which can attenuate or support the wireless propagation.
Todd Litman of the Victoria Transport Policy Institute in Canada makes the case for enlarged and improved transport-related data. Comprehensive, high quality data is useful, or even essential, for many types of decision making and transport is no exception. Planners and researchers can cite countless situations where their understanding of transport problems and their ability to evaluate potential solutions is constrained by inadequate data.
