13 Promoters of this computerized highway have great hopes for its future. By 2010, telematics may well be incorporated into one of the major highways in the United States. If successful, by 2020, as the price of microchips drops to below a penny a piece, telematics could be adopted in thousands of miles of highways in the United States. This could prove to be an environmental boon as well, saving fuel, reducing traffic jams, decreasing air pollution, and serving as an alternative to highway expansion.

这种计算机化的公路的倡导者对其未来的应用充满希望。到2010年，远程信息技术很可能应用于美国的一条主要公路。如果成功的话，到2020年，当微芯片的价格降到一片一美分以下时，远程信息技术就会应用在美国成千上万英里的公路上。这对环保也会很有利，能节省燃油，减轻交通阻塞，减少空气污染，还可用作公路扩建的替代办法。
