RWIS and MDSS

• Larger network of RWIS increases MDSS effectiveness

• RWIS – MDSS Training Similarities– Computer Technology– RWIS not complete tool?

SSI RWIS Advancements

• Newer RWIS Platform– Very Expandable (Traffic,

Homeland Security)– More reliable– Easier to maintain– Device Control capabilities

Pavement Sensor Options

Thermo SCAN –Pavement Temperature Only

GroundHog – Inpavement Wireless Traffic Sensor

FP 2000 – SSI making improvements to the sensors reporting capabilities.

SSI Forecast Services Overview

Use of improved weather modeling (utilization of higher resolution models and ensemble forecasts) as the basis for all forecast products.

The AIT maintenance treatment strategy is appended to the SSI SCAN*Cast recommending pre-storm, during storm, and a post-storm treatment strategy for particular site based on “best practices”

Strategy is modified as forecast is updated or changes

Storm Logic forecast considerations

Pre-stormPrecipitation type and intensity (rain or no rain)Pavement temperatureWind speed

During stormPrecipitation type and intensityPavement temperature and trends

Post-stormWind speedPavement temperature until dry pavement

Guidance on how to best treat roadway to optimize safety and costs (material/labor)

Training tool for agencies just getting started in anti-icing programs or for new supervisors

User friendly approach – easy to understand

Benefits of Storm Logic

Based on current customer feedback:1. Customization of treatment

recommendations based on individual agencies.

2. Enhanced road condition and treatment recommendations to provide more specific recommendation timing during the next 24 hours – incorporate modules from MDSS prototype.
