The Road Weather System for Canada is now a mature proposal for serious consideration by senior government officials at the provincial, territorial, and federal levels. It would provide a framework for close collaboration in the deployment of a national integrated network of RWIS stations to serve the National Highway System. It would provide the basic network onto which provinces and territories could build to expand the network over the remaining non-NHS highways within their boundaries. Cities and municipalities could add RWIS systems to the network by respecting the national RWSC standards and so gain entry into the data and products from the broader network. By allowing the Meteorological Service of Canada to ingest the RWSC data, the provinces and territories would be maximizing the return on their RWIS investments by obtaining enhanced weather forecasts and gridded forecast data sets with which to generate pavement forecasts for many more sites and, eventually, for entire road networks. The adoption of RWIS technology by the provinces and territories, and in time by the municipalities, within a broader programme of pro-active winter maintenance, will provide safer, more efficient and environmentally sustainable road transportation in Canada at less cost to Canadian taxpayers.
