Range of Solutions u Web-Based MDSS • Offers agencies a simple pathway to full MDSS implementation u Stand-Alone MDSS • Provides full-featured MDSS functionality u In-Vehicle MDSS • Provides route-specific forecasts, recommendations and radar back into the truck

Solid Scientific Foundation u MPower™ weather forecasts • Ensemble-based • Meteorologist edited • High-resolution grids for sitespecific forecasts anywhere u Hi. CAPS™ pavement forecasts • Sophisticated Mass / Energy balance model • Enhanced with PFS MDSS module additions • Validated with field observations

Web MDSS u Range of Options • “Classic MDSS” u Provides weather and pavement forecasts assuming no maintenance is performed. • “Best Practices MDSS” u Classic features plus customized recommendations tailored to agencies’ typical response to combinations of weather and road conditions. • “Dynamic MDSS” u Provides recommendations dynamically generated by the MDSS. Adheres to local resource constraints, but perhaps stepping outside of normal operating practices – provides scientifically sound alternatives to normal practices.

“Classic MDSS” • Traditional service providing unlimited sitespecific forecasts, enhanced map graphics, ‘nomaintenance’ pavement forecasts, and other supporting data displays

Enhanced Web MDSS Solutions • “Best Practices” and “Dynamic MDSS” provide an easy step up from the traditional service by adding maintenance recommendations & results

Stand-Alone MDSS u Comprehensive Solution • Integrates past & present maintenance actions, weather, and road condition reports • Adheres to resource & practice constraints, and allows for dayto-day adjustments of those constraints • Provision for optimal, standard, and ‘what-if? ’ virtual maintenance actions • Features geared toward all levels of management u One-stop-shop concept u Developed in concert with PFS states
