| 摘要： | In this paper a case is made for using a little-used part of the shortwave radio spectrum as a cost-effective means of broadcasting digital traveler information to rural and intercity users. Although the subject is technical, the material is provided in an easy-to-digest format. The target audience is state and federal transportation officials who believe that providing real-time traffic information is as much a part of transportation as building and maintaining highways. The approach uses low-cost off-the-shelf technology for both transmitting and receiving, and promises statewide coverage for a total investment comparable to a simple highway advisory radio installation, about $10,000. The paper also describes how state departments of transportation or state police organizations can set up wide-area low-cost broadcasting facilities using a simple personal computer work station as an interface. The preliminary research needed and a strategy for follow-up operational tests are also described. The proposal describes the benefits and discusses the downside risks of developing this cost-effective medium for broadcasting traveler information. |
