California Partners for Advanced Transportation Technology

In this paper, the authors, although agreeing that deployment is the ultimate goal of Intelligent Transportation Systems (ITS) research and funding, believe that there is not sufficient knowledge of how, why and when to deploy specific ITS functions They contend that continued research and testing (R &T) is still necessary to assure effective future deployment. The article identifies critical needs for R & T and is based to a large degree on the authors' experience in the California PATH research program.
