This appendix contains a technical description of the methods used to determine transit asset conditions and future investment requirements. It is primarily a description of the Transit Economic Requirements Model (TERM) and one of the key improvements made to the model for this reporting cycle, stemming from the 1999 National Bus Condition Assessment. Transit Economic Requirements Model The Transit Economic Requirements Model (TERM) provides estimates of the total annual capital expenditures required to maintain or improve the physical condition of transit systems and the level of service they provide. The estimate represents the total urbanized area transit investment required by all levels of government. The model also generates estimates of current transit conditions and performance evaluates the impact of varying levels and types of investment on future conditions and performance.TERM's Structure TERM forecasts investment needs via four distinct modules:
The TERM modules are further subdivided by mode, asset type, and urban area characteristics. In addition to investment estimates, TERM generates estimates of the physical condition of the Nation's transit assets, as described in Chapter 3. |
