compare the cost-effectiveness of different types of CMAQ projects in different states.

To address these problems, it is the author’s recommendation that FHWA ask states to

  1. Add information on project life to the database, so that total emission reductions can be calculated for project cost-effectiveness analyses; and

  2. Report total cost for a project (including costs in all years whether covered by CMAQ or other funding sources), along with CMAQ obligations for the project in the fiscal year.

FHWA also should consider ways of addressing problems due to inconsistent data, methods, and assumptions in estimating emission reductions, without imposing unreasonable reporting burdens on states.
