| 摘要： | These guidelines have been developed to help Virginia Department of Transportation (VDOT) personnel effectively operate highway advisory radio (HAR) systems. Operators should continually bear in mind that it is of paramount importance that HAR messages be accurate, timely, and useful. While this document provides guidance, it can in no way replace the sound judgement of HAR operators. The guidelines are organized in five sections: personnel, transmitter placement, advisory signing, message development, and equipment maintenance. Each section contains information that applies to both portable and permanent HAR. Appendices A and B contain sample HAR messages for incident and non-incident situations. Appendix C includes information on maintaining and updating the guidelines. |
