| 摘要： | The 1999 Status of the Nation's Highways, Bridges, and Transit: Conditions and Performance report to Congress shows that the higher federal highway funding levels of the past few years, authorized by the Intermodal Surface Transportation Efficiency Act of 1991 and the Transportation Equity Act for the 21st Century, have begun to pay off with better pavement, improved bridges, and safer highways. In general, conditions are worse in urban areas where more than 9% of the interstate highways are rated as poor. Even this rate, however, reflects a slight improvement from the 1997 level. Fewer than 3 in 10 of the nation's bridges are rated as deficient--either structurally deficient or functionally obsolete--down from 35% since 1992. In 10 years, the fatality rate and the injury rate on the nation's roads have dropped markedly. Congestion is a growing problem in virtually all urban and suburban areas. Travel under severe or extreme congested conditions doubled from 1982 to 1997--from 14% to 36%--costing $72 billion in wasted fuel and time. |
