Welcome to DOT ITS Knowledge Resources
Intelligent transportation systems (ITS) provide a proven set of strategies for advancing transportation safety, mobility, and environmental sustainability by integrating communication and information technology applications into the management and operation of the transportation system across all modes. This website presents summaries on the benefits, costs, deployment levels, and lessons learned for ITS deployment and operations from over 20 years of ITS evaluation studies, research syntheses, handbooks, journal articles, and conference papers tracking the effectiveness of deployed ITS.
