摘要：	In 1998 Northern Arizona University (NAU) and the Arizona Department of Transportation (ADOT) designed and implemented the prototype of a variable speed limit (VSL) system for rural highways. The VSL system implements a real-time fuzzy control algorithm that utilizes information provided by Road Weather Information Stations (RWIS). This system continuously displays highway speeds appropriate to the atmospheric and road surface conditions at locations of interest along the I-40 corridor in rural northern Arizona. At the time of this initial project, none of the RWIS sites along I-40 were providing the complete data set needed for full utilization of the fuzzy control algorithm. During the project described in this paper an RWIS site on I-40 was fully upgraded so that it could be used as a test site to monitor the complete data set of atmospheric and road surface conditions needed by the fuzzy control algorithm. In addition to this a traffic detection system was added to the RWIS site.
