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

MDSS – User interface

• Secured log-in• Map based display• RWIS + Road

weather segments• Danger level for

upcoming hours• Time cursor

Main display

MDSS – User interface

• History graph :– Measured data– Precipitation– Alarms– Status

• Forecast accuracy– Comparision forecast /

measurement

MDSS – User interface

• Country summary

• Still pictures

• Satellite / radar pictures

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 2006 11/19

Example MDSS-Code 066623

• Compact high fog, locally icing drizzle = black ice

MDSS-Code = 06662306 freezing rain66 freezing rain2 wind: 30-60kmh3 Temp. +/- 0°C.

MDSS - Stakeholder Meeting, Falls Church, VA, 11th August 2006 12/19

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.

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 2004 - 2005).

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).
