Summary
This document outlines the U.S. Department of Transportation’s (USDOT) strategic initiatives and funding priorities for Intelligent Transportation Systems (ITS) as of 2014. The USDOT serves as a primary national funder for ITS research and development, investing over $100 million annually to accelerate technology deployment. The overarching vision is to establish connectivity across the transportation network using advanced wireless technologies, thereby maximizing safety, mobility, and environmental sustainability. The agency identifies connected vehicles, automation, enterprise data, emerging technology, interoperability, and deployment as key priorities for the subsequent five years. A central focus of the USDOT’s strategy is the advancement of connected vehicles, which communicate with other vehicles, infrastructure elements like traffic signals, and mobile devices. This technology builds upon existing navigation applications by providing real-time data capable of preventing crashes and improving fuel efficiency. The USDOT has transitioned from extensive research and testing to a Connected Vehicle Pilot Deployment Program, inviting cities and communities nationwide to implement these technologies. Privacy protections are emphasized, with technical controls designed to prevent vehicle tracking and ensure that communicated data does not identify drivers. The document also details the integration of connectivity with automated vehicle technologies. While current automation requires human monitoring, research into fully self-driving vehicles is underway. Connectivity is identified as a critical input for automation, allowing vehicles to perceive surroundings that sensors alone cannot address. Potential benefits of automated vehicles include crash avoidance, reduced energy consumption and emissions, improved travel time reliability, and enhanced accessibility for persons with disabilities and the aging population. Furthermore, the USDOT promotes innovation through Integrated Corridor Management (ICM), which coordinates the management of freeways, side roads, and public transit as a unified network. Demonstration sites in Dallas, Texas, and San Diego, California, utilize decision support systems to monitor traffic and optimize signal timing. Modeling results indicate that ICM yields a tenfold return on investment for taxpayers through fuel savings, reduced congestion, and lower toxic emissions. Finally, the Mobility Services for All Americans (MSAA) initiative addresses transportation access for seniors, persons with disabilities, and the economically disadvantaged. By coordinating fragmented human service transportation systems through centralized technology, the USDOT aims to improve access to essential services such as healthcare and employment. The document concludes by encouraging industry and community partners to leverage USDOT research to launch local ITS initiatives.
