| 摘要： | Increasing travel demand and lack of sufficient highway capacity are serious problems in most major metropolitan areas in the United States. Large metropolitan areas have been experiencing increased traffic congestion problems over the past several years. The total delay that drivers experienced has increased from 0.7 billion hours in 1982 to 3.7 billion hours in 2003. Combining the 3.7 billion hours of delay and 2.3 billion gallons of fuel consumed due to congestion, leads to a total congestion cost of $63 billion dollars for drivers in 85 of the largest metropolitan areas of the nation. In spite of the implementation of many demand management measures, the congestion in most urban areas is still increasing. In many areas congestion is no longer limited to two peak hours in a day; however, it is extended to two to three hours in the morning, afternoon and evening. Thus, the congestion experienced on urban and suburban freeways and arterial streets results in delays to the motorist, excess fuel consumption and a high level of pollutant emission not only during the peak hours in a day, but also for several hours throughout the day. SCATS (Sydney Coordinated Adaptive Traffic System) is a computer controlled traffic signal system, developed in Australia and used widely in the Pacific Rim. |
