This is the testimony of Eleanor Chelimsky, Assistant Comptroller General, Program Evaluation and Methodology Division, General Accounting Office, on the subject of traffic congestion and federal approaches for dealing with it. The discussion is centered on the following basic points: 1) traffic congestion is a worsening problem; 2) the federal government has a role in improving mobility; 3) intelligent vehicle and highway systems are promising but need further testing; 4) there are other low-cost approaches that need to be considered; and 5) the reauthorization of the Surface Transportation Act should contain mobility-enhancing provisions. |
