| 摘要： | The purpose of this report is to update the estimates of the costs remaining to deploy Intelligent Transportation Systems (ITS) infrastructure elements in the 75 largest metropolitan areas in the United States. Updates to this working paper coincide with the results from tracking the deployment of the integrated ITS infrastructure in the United States. To date, deployment tracking results are available for 1997, 1999, 2000, 2002, and 2004. The initial version of the working paper (dated September 1999) was written to update the FHWA 1995 cost estimate and to develop estimates of the investments that must still be made using the 1997 deployment tracking results. Deployment tracking results from 1999, 2000, and 2002 were incorporated into the first, second, and third revisions of this paper (dated August 2000, July 2001, and October 2003, respectively) with the majority of the updates contained within the addendum to the original document. With the 2004 deployment tracking data now available, the national deployment cost estimate can be updated again. However, for this iteration the new cost estimate is documented as a standalone report. Details on the methodology for developing estimates, and how costs and quantities were derived can be found in previous versions of the working paper. |
