4.2 TRANSPORTATION AGENCY COSTS
Agency costs refer to the expenditures incurred by the facility owner or operator in providing the transportation service. For fixed assets, agency costs are typically placed into seven major categories : advance planning, preliminary engineering, final design, right-of-way acquisition and preparation, construction, operations, preservation, and maintenance. In some cases, disposal of the fixed asset at the end of its service life involves some costs that are referred to as salvage costs. For movable asset (rolling stock), agency costs typically comprise acquisition, vehicle operating preservation, maintenance, and disposal costs.
