公路通讯,包括为公路管理、工程、运输调度以及安全监理服务的有线通讯和无线电通讯网。当今令人注目的是,许多国家都在迅速发展有/无线能汇接,还能与微抗、传真、水运、航空、卫星联网的功能齐备的移动通讯系统。随着我国社会主义经济的发展,改变公路交通落后状况已日益迫切。改变公路交通落后状况的办法,一是改造和新建公路,提高车辆的通行能力;二是提高公路的管理水 Road communications, including wireline and radiocommunications networks for road management, engineering, transport scheduling and safety supervision services.
