The route treatment

This article examines the operation and testing of a route-based condition forecasting service in England, Scotland and Wales. This delivers individual forecasts for each salting route, by applying an energy balance model at multiple points across the road network to compute road surface temperature (RST) and condition. Aggregated data provides forecasts with time of first "zero crossing", minimum RST and treatment recommendations. Verification methods compare forecast and observed RST: statistics include overall accuracy, false alarm ratio, and frost-detection ratio. Precision is assessed by mean error and root mean square error. During the 2006/2007 winter season the process was tested in South Wales, central northern England and selected routes in Scotland. Forecasts were compared to traditional forecasting and, although the number of treatments on a given night were not always reduced, potential was shown for overall reductions and therefore cost savings and environmental benefit.
