CDOT Thermal Mapping Report

Thermal Mapping surveys were carried out on approximately 1000 miles of the Colorado Department of Transportation’s (CDOT’s) roads. The purpose of these surveys was to identify road surface variations across the network to determine whether forecast Thermal Maps or the data from the surveys would be useful to decision-makers in the CDOT regions. The distribution of road surface temperatures across the network and identifying Climatic Domains for the regions enabled Vaisala to look at current weather station locations and whether there were any gaps in coverage. The use of forecast Thermal Maps is one that will be determined by the Boulder maintenance area in winter 2014/15. The Thermal Maps will be tested using Vaisala RoadsDSS and the final decision on whether the Thermal Mapping could be valuable to CDOT operations will be made in conjunction with the decision-makers prior to any statewide implementation plan. Vaisala has advised on potential weather station locations based on the Thermal Map findings which would complement the current setup.
