6.0 Conclusion

The collection of road weather information can provide decision support to transportation managers and contribute to more accurate weather forecasts. The recommendations in this document are designed to satisfy as many road weather monitoring, detecting, and prediction requirements as possible. The recommendations encourage uniformity in ESS siting and in the application of the road weather observations. Many of the recommended criteria include a range of values. These ranges reflect both the complexity of the roadway environment and the need for additional research. The recommendations suggest siting decisions are best made by a team of transportation operations, road maintenance, and weather experts.
