Intelligent transportation systems (ITS) projects include a wide variety of applications where communications technologies are connected to transportation systems. Rural and small metropolitan areas can see benefits to transportation safety, mobility, and operations, but they may experience challenges due to long distances, smaller populations, telecommunications connectivity issues, and funding for transportation improvements.
From 2019-2023, the NADO Research Foundation conducted research supported by the U.S. Department of Transportation’s ITS Joint Program Office and developed the report Rural and Small Metropolitan Intelligent Transportation Systems: Case Studies on Developing and Deploying ITS in Rural Regions and Smaller Communities (PDF, draft final report, May 2023).
This research combined a review of existing literature on rural and small metropolitan ITS with interviews of transportation professionals and primary source research to identify case studies. The report presents case studies highlighting the work of state, regional, local, and nonprofit agencies using ITS in rural, small metropolitan, and suburban or exurban places around the United States. Several themes emerged across the cases, including important roles for state, regional, and local agencies in preparing for and investing in ITS; the significance of capacity building for staff on ITS; and the need to invest in rural broadband along with ITS.
