    1. SIRWEC WORKSHOP “How to transform road weather information into real operations” Chairman Professor John E Thornes University of Birmingham UK 25 Years of SIRWEC

    2. THE QUESTIONS What Kind of weather information do Highway Engineers want? Should Meteorologists be suggesting treatments – or should meteorologists just stick to weather forecasting? Computer acts as an interface Are residual salt measurements good enough yet? Common level of service?

    3. The Next Generation (XRWIS)

    4. XRWIS Decision Algorithm RED Route Requires Salting 10g/m2 YELLOW Standby GREEN No Salting Required Mean RST <0 degC and Road Ice Forecast Mean RST >0 <1 degC OR RST <0 Road Dry Mean RST >1 degC

    10. DISCUSSION Different Climates need different solutions Need a flexible Decision support system Need to take residual salt into account We heard examples and experiences from the US, Denmark, Austria, UK, Quebec, Sweden Selective salting and dynamic routing ok for ice and frost but not for snow!

    11. THE FUTURE Make sure that automation improves life for operators as well as managers (not too much form filling)? Better forecasts for blowing snow? Better chemicals? Better measurement of residual chemicals? Use traffic/satellite data for verification?
