Evaluation and deployment tracking activities are critical to an understanding of the value, effectiveness, and impacts of the ITS Program activities in alignment with U.S. DOT goals. 23 USC Sect 515 paragraph (g) outlines the requirement to maintain a repository for technical and safety data collected as a result of the federal projects carried out under the ITS program and the ITS Benefits, Costs, and Lessons Learned (BCLL) Database, created in 1999, does that by tracking and documenting the effectiveness of deployed ITS.
