现代汽车离不开先进的公路设施,在经济和技术迅速发展的今天,解决交通堵塞、避免交通事故,改进车辆运行效率,除了用先进的电子技术改造汽车、使之智能化之外,研究和建设“智能型”公路、实现现代化公路及交通管理是今后一、二十年的目标。在这方面,许多工业国家,尤其是汽车和公路技术高度发达的美国,在这方面作了有益的尝试。 纽约附近的长岛是美国公路管理中心之一,负责管理135哩的交通干线,其中包括声名狼藉的长岛高速公路 Today, with the rapid development of economy and technology, modern cars can not be separated from advanced road facilities. In order to solve traffic congestion, prevent traffic accidents and improve vehicle operation efficiency, in addition to using advanced electronic technology to transform automobiles and make them intelligent, The goal of building “smart” highways and realizing modern road and traffic management is one or two decades from now. In this regard, many industrialized countries, especially the United States, which has a highly developed automotive and road technology are making useful attempts in this regard. Long Island, near New York City, is one of the U.S. road management hubs that manages 135 miles of major traffic routes, including the infamous Long Island Highway
