Appendix A: ITS Unit Cost Data
(as of September 20, 2004)
ITS unit costs are available in two formats: unadjusted (see Section A.1) and adjusted (see Section A.2). The unadjusted format presents costs data in its original value along with the dollar year of the capital and operating and maintenance (O&M) costs. The adjusted format presents capital and O&M unit costs in 2003 dollars. The dollar year the cost data were adjusted from is provided along with the index used to adjust the cost data. If the cost data are 2003 values, then no adjustment was made. The unit costs presented in this appendix represent data collected through September 30, 2004.
Information on indexes used to adjust the costs is provided in Table A. The indexes used in the adjustments are maintained by the Bureau of Labor Statistics (www.bls.gov). The year-by-year index series from 1995 to 2003 can be accessed at this website. Index information is also available in the ITS Costs Database (www.benefitcost.its.dot.gov).

The index number in Section A.2 (far left column) corresponds to the index used to adjust the cost data. The index is representative of the ITS element. For example, the first element in Roadside Telecommunications, DS0 Communication Line, is tagged with Index 1. Index 1 is the WPU1176 index and is applied to communications and related equipment. The capital cost range is an adjusted value and was adjusted from a 1995 value (see date directly to the right of the capital cost range). The O&M costs are 2003 values obtained in Mitretek's analysis (as such, no adjustment needed).
