Statewide ITS Architecture Assessment Project Documents

The Statewide ITS Architecture (SWITSA) Assessment and Support project assessed how statewide and regional ITS architectures (RITSAs) have been used in support of both regional transportation planning activities and actual transportation investments.  It identified a number of institutional barriers preventing RITSAs from being used more effectively, ranging from inadequate funding for architecture maintenance and training to fundamental differences in perspective between technology experts and more traditional transportation experts.

The following documents address the outcomes of the study, including the definition of a Business Case for dedicating resources to RITSAs in California, along with planning guidance for ITS activities. These include the integration of RITSA development, updates and maintenance with regional and statewide transportation planning activities.  A key component is addressing the role of Caltrans Districts in working with regional stakeholders to define common interests and projects that will benefit both a region and the State Highway System (SHS).
