| 摘要： | The U.S. transportation system serves hundreds of millions of travelers and handles millions of tons of freight each day to help ensure the efficient movement of people and goods in support of personal goals and domestic and international commerce. A well functioning transportation system is essential for business travel and tourism, yet no national data have been collected on long-distance, intercity passenger travel by surface transportation modes since 1995. A strong economy depends on state and regional investments in freight corridors to keep freight moving, but industry-based data on freight shipments, focused on supply chain linkages and local goods movement, are not collected. Only coarse national-level data are available on intercity commodity flows. Increased energy efficiency and reductions in greenhouse gas emissions from vehicular travel are being sought to reduce the transportation sector's adverse environmental impacts, but data on vehicle use necessary to monitor progress are no longer being collected. Good travel data are essential to support critical policy choices and multimillion dollar investments facing decision makers. Unfortunately, as the previous examples demonstrate, the travel data available today are inadequate to meet this demand. The most comprehensive data are collected by the federal government in periodic surveys. |
