MDSS – Austria Realisation MDSS - Stakeholder Meeting, Falls Church, VA, 11th August /19

MDSS - Stakeholder Meeting, Falls Church, VA, 11th August 2006 MDSS - Components Weather forecast (incl. MDSS-Codes) Meteorological office Road weather information systems (RWIS) Mobile data acquisition MDSS Maintenance vehicle data Measured road data Maintenance decision support informations 4/19

MDSS - System Full system redundancy in two locations High availability (99.8%) 700 RWIS, –Viasala, Luft, Micks, Boschung –150 users, 1,600 miles of highway Location 1Location 2 MDSS - Stakeholder Meeting, Falls Church, VA, 11th August /19

MDSS – Sofware Platform Data acquisition Configuration Nowcasting / Forecasting Treatment recommendation Alarming Data display / reporting Modules MDSS - Stakeholder Meeting, Falls Church, VA, 11th August /19

MDSS – User interface Secured log-in Map based display RWIS + Road weather segments Danger level for upcoming hours Time cursor Main display MDSS - Stakeholder Meeting, Falls Church, VA, 11th August /19

MDSS – User interface History graph : –Measured data –Precipitation –Alarms –Status Forecast accuracy –Comparision forecast / measurement Other displays MDSS - Stakeholder Meeting, Falls Church, VA, 11th August /19

MDSS – User interface Country summary Still pictures Satellite / radar pictures Other displays MDSS - Stakeholder Meeting, Falls Church, VA, 11th August /19

MDSS - Code format XXYYzZ XX Change on the road surface YY Weather, Precipitation z Wind Z Temperature characteristics MDSS - Stakeholder Meeting, Falls Church, VA, 11th August /19

Example MDSS-Code Compact high fog, locally icing drizzle =black ice MDSS-Code = freezing rain 66 freezing rain 2 wind: 30-60kmh 3 Temp. +/- 0°C. MDSS - Stakeholder Meeting, Falls Church, VA, 11th August /19

MDSS - Codes MDSS - Codes are generated every hour for 3h, every 6h for 32h and every 12h for 72 hours MDSS - Codes are generated for approximately 220 sections of road ( 1’600 miles of highway) MDSS - Codes communication between road manager and the weather prognosticator are very efficient. 10/19 MDSS - Stakeholder Meeting, Falls Church, VA, 11th August 2006

Probability forecast for precipitation. 100% 0% Probability MDSS - Stakeholder Meeting, Falls Church, VA, 11th August /19

Probability forecast for snowfall/snow cover (today and future) MDSS - Stakeholder Meeting, Falls Church, VA, 11th August /19

Actual Treatment No calibration is possible without the actual treatment. No treatment recommendation is possible without the actual treatment. Same result as MDSS- Colorado (Winter ). = Spreader - Data is necessary MDSS - Stakeholder Meeting, Falls Church, VA, 11th August /19

Treatment recommendations MDSS - Stakeholder Meeting, Falls Church, VA, 11th August /19

Calibration with Mathematician Mathematician expertise helps calibrate the MDSS - System. –This expertise provides that the MDSS - System works with a proven maximum effectiveness. –This effectiveness must be accepted from the owner of the road network (e.g. 92%). The owner knows now under which conditions the MDSS - System can’t be used (e.g. radar- shadow). MDSS - Stakeholder Meeting, Falls Church, VA, 11th August /19

Concept was proposed for the State of Ohio Evaluation of ODOT Roadway / Weather Sensor Systems for Snow and Ice Removal Operations, Final Report June 2003 Helmut T.
