In 2007, Nova Scotia Transportation and Infrastructure Renewal (NS TIR) contracted AMEC Earth & Environmental to perform a thermal mapping pilot project. AMEC used infra red sensors on data collection vehicles to develop Thermal Fingerprints for the western half of Trans Canada Highway 104 in Pictou County. Thermal Fingerprints were developed for each of the three classic weather types: Extreme, Intermediate, and Damped. The Night Icing Potential (NIP) prototype was developed as a new operational guidance product for use by winter maintenance operators. NIP uses RWIS forecasts together with Thermal Fingerprints of a roadway to assess the potential for night icing anywhere along the entire length of a roadway. NIP returns the earliest time for the onset of the icing process for each kilometer-long segment of roadway where a night icing potential exists. The product is presented in map form with the icing times plotted along road segments which are also colour-coded according to icing onset time. This project was nominated for the TAC 2007 Road Safety Engineering Award. For the covering abstract of this conference see ITRD number E216597.
