Road Condition and Treatment Module
RCTM
•Added explanations for system recommended treatments
•Modified logic used to determine recommended treatment
plans
•Instituted subsurface temperature profile correction scheme
•Added comprehensive chemical selection capability including
Caliber and IceBan
•Added information derived from blowing snow algorithm to
recommended treatment process
•Updated system to track the amount of water on the roadway
and the phase of the water (e.g. snow, slush, ice, wet,
chemical wet, etc.)
3
Miscellaneous Upgrades
•Altered static weighting scheme for quantitative precipitation
forecasts
•Examined and adjusted conditional probability threshold for
declaring snow
•Modified Forward Error Correction (FEC) Scheme
•Changed insolation source
4
Display Upgrades
•Adapted and enhanced graphical user interface to accommodate
aforementioned changes

MDSS Technology Transfer Challenges
Road Temperature Model
No longer supported
Not robust
New models
FASST
METRo
MDSS Display Code
Falls short of the FRD
Lacks tactical alert capability
MDSS Release Adoption
Little support requested
Used for ideas and concepts
Organizations want to minimize risk
Meets project goals
