The U.S. Department of Transportation (USDOT) has released a 2014 update of the Intelligent Transportation Systems (ITS) Benefits, Costs, and Lessons Learned Report, along with a series of accompanying fact sheets. The report is based on three related Web-based databases, known collectively as the ITS Knowledge Resources. The ITS Joint Program Office's evaluation program developed the Knowledge Resources to support informed decision making regarding ITS investments by tracking the effectiveness of deployed ITS. The Knowledge Resources contain over 18 years of summaries of the benefits, costs, and lessons learned of specific ITS implementations, drawn primarily from written sources such as ITS evaluation studies, research syntheses, handbooks, journal articles, and conference papers. They can be accessed online at www.itskrs.its.dot.gov. The report has been designed to provide flexibility to the user-information is readily available and accessible via the web, using a personal computer or a mobile device or tablet. The accompanying fact sheets present information on the performance of deployed ITS, as well as information on the costs and lessons learned regarding ITS deployment and operations. There are a total of 20 fact sheets representing the 16 taxonomy areas. Four of the taxonomy areas (arterial management, freeway management, transit management, and driver assistance) have enough data to require more than one fact sheet.
