Potential Benefits: Temperature Measurement System of Sensors for Smart Road Anti -icing and Deicing Objective To increase the efficiency of winter road management by providing more accurate road temperature measurements. Premise Anti -icing (proactive snow and ice control before the storm through brine application for "bottom -up" melting) and Deicing (snow and ice control using reactive brine and prewetted road salt application for "top -down" melting) regiments rely primarily on road temperature measurements as the guiding principle on how much salt and brine needs to be placed. This is because the effectiveness of these ice melting agents can vary as much as 10X from a drop in temperature of 10°. The current system in place is only accurate to a degree or two. As such, current deicing regiments put the safety of residents first and overuse deicing material. We can preserve safety, protect the environment, and save money with smarter real- time sensing using an internet of things solution. Potential Benefits Reduced Salt and Brine Usage • Direct Cost Savings a A 10% reduction would conservatively save $60,000 a year in material costs. o Estimated reduction in material usage of 10-40%. Reduced Vehicle Maintenance and Use o Deicers are highly corrosive and area significant contributor towards the cost of vehicle maintenance o Effective anti -icing regiments vastly increase the effectiveness of plowing efforts during the storm. Reduced Damage to Roads o Plows damage the roads and are one of the primary reasons roads need to be repaved. a Improved Anti -icing regiments decrease the need for plowing. Safe • Improved accuracy o Fewer trouble spots that cause accidents. o Note too little is ineffective and too much brine can actually make the pavement more slick than if we did nothing —accuracy is critical for safety • "Hot Spot" Monitoring o Direct temperature measurements of known hot spots to ensure accurate deicing. • High priority locations such as hospitals, schools, and Downtown have their own sensor. Environmental Impact • Reduced Chloride Loading (Calcium Chloride Deicer) o Less corrosive waterways. • Reduced BOD Loading(Anti-ices with beet sugar added to drive lower melting point temperature) o Improved oxygen levels in the surrounded aquatic ecosystems.
