  1. Using Weather Information to Improve Route AGILE conf. 2012 Paul litzinger Gerhard navratil Åkesivertun Daniela knorr University of applied sciences technikumwien Vienna university of technology Swedish national defence college UBIMET gmbh

  2. Overview The traditional approach considers legal speed restrictions only. The approach using static weather information determines realistic driving speed based on the actual weather conditions

  3. Weather and it’s influence on traveling Influence of weather events on the roadway and traffic operations

  4. List of speed and capacity reduction

  5. Ubimet provided Real weather data. Ubimet: Ubimet not only uses public weather data but also accesses the data of the largest private weather observation network in Central Europe Data formats: Gridded Binary – 6hr update (10km) Network common data format – 1 hr update (4km)

  6. Route planning using weather information Uwind = |U| + |V| + |UST| DegreeCelisus = Kelvin – 273.5 The values for wind speed, temperature, and precipitation were then reclassified to match the categories in Table 2 and provide values for speed reduction.

  7. Route planning using weather forecast data While the static weather routing uses only one weather situation, the dynamic approach includes the hourly updated weather forecasts.

  8. Route planning(Assumption) Drivers move with an average speed equalling the speed limit. The interval of the weather forecast data is 1 hour. The road network consists of highways with a speed limit of 130 km/h. Service areas: black rings Start position: black dot Different weather condition: grey area Road network : black lines
