Best Practices for Road Weather Management Version 2.0
Improving the Wyoming Road Weather Information System
A two-year study of the Wyoming Road Weather Information System (RWIS) indicated that the system will facilitate and improve maintenance operations and enhance the safety and convenience of highway travel if certain critical improvements are made. Without these improvements, benefits will be marginal and continued operation may not be cost effective. Areas identified for improvement include: upgrading the radio communications system; integrating the two systems presently in use (SSI and Vaisala); upgrading software to improve data displays and simplify use; adding supplementary weather information such as Nexrad radar, satellite images, and weather maps; making RWIS data and weather information directly available in every maintenance shop, preferably via satellite communications such as that available from DTN; installing additional roadside weather stations; improving site selection procedures; and and provide additional training. Other recommendations included improving forecasting services, conducting research to determine visibility sensors suitable for blowing snow conditions, archiving data, and assigning personnel dedicated to managing and maintaining the RWIS system.
