在亚特兰大市进行的用激光器代替普通电线的实验性交通控制系统试验证明,即使在不良气候条件下,运转也是可靠的。去年,由斯佩里·兰德公司的系统管理部进行的试验中,沿着2.3英里长的一段高速公路上使用砷化镓二极管作为中继器向中心交通控制计算机发出或发回信息。据该部交
Experiments with experimental traffic control systems using lasers instead of plain wires in Atlanta demonstrated that the operation is reliable even in unfavorable climatic conditions. Last year, Sperry RAND’s Systems Management Division conducted a test using a gallium arsenide diode along a 2.3-mile stretch of highway as a repeater to send or send back information to a central traffic control computer.
