今日美国全年因交通阻塞造成的损失数额巨大。有鉴于此,参议院环保和公共工程委员会已通过一系列决议,努力在5年之内在部分地区完成智能公路体系。所谓智能公路是运用高技术来避免交通阻塞。这种公路体系一旦实现至少可以把城市中的交通阻塞减少一半,交通事故可望减少80％左右。 Today, the U.S. toll is huge due to traffic congestion throughout the year. In view of this, the Senate Environmental Protection and Public Works Commission has adopted a series of resolutions and endeavored to complete the smart highway system in some areas within five years. The so-called smart highway is the use of high technology to avoid traffic congestion. Once such a highway system is implemented, the traffic congestion in the city can be reduced by at least half and traffic accidents are expected to be reduced by about 80%.
