About $80 billion of the $155 billion authorized by the act for the six-year period ending in fiscal year 1997 can be used to underwrite either highway; mass transit; or nontraditional projects, such as high occupancy vehicle lanes. The flexibility allowed under the act will be critical as states and localities begin tackling highway congestion, air pollution, and investing in highway and mass transit infrastructure. This report evaluates the (1) extent to which states and localities have used the act's highway and mass transit capital funds flexibly to finance different types of projects; (2) factors that have influenced the flexible use of the act's funds; and (3) adequacy of analytical tools in deciding on transportation investments. GAO summarized this report in testimony before Congress; see: Transportation Infrastructure: Implementation of Funding Flexibility Under ISTEA and Use of Transportation Control Measures, by Allen Li, Associate Director for Transportation Issues, before the Subcommittee on Investigations and Oversight, House Committee on Public Works and Transportation.
