Essential functions of MDSS
- Road conditions – MDSS accepts current road condition observations from manual sources, snowplow-mounted sensors, and GPS location-based equipment.
- Maintenance treatments – Plowing and chemical applications are reported manually or by instrumented snowplows.
- Weather conditions – MDSS considers current and recent weather conditions affecting the road surface.
- Roadway state – Physical and chemical models take into account factors like the pavement, the mix of water, ice, chemicals, and grit, to better predict temperature, moisture type and depth, and chemical concentration.
- Feasible treatments – MDSS considers maintenance treatments that fall within agency-defined constraints for equipment, materials, operating hours, and crew size for each road segment.
- Agency priorities – MDSS considers the acceptable levels of service for each highway segment.
- Predict road surface behavior – MDSS physical and chemical models predict the future behavior of road surfaces for every feasible maintenance treatment.
- Treatment recommendations – MDSS recommends the most cost-effective treatments to maintenance supervisors and truck operators that will safely maintain the level of service.
The potential for significant cost savings and improved service
A case study of five New Hampshire winters showed that MDSS use would have required 23% less salt while providing the same level of service — AND an overall cost/benefit ratio of 8:1. In its deployment of MDSS in 2008-2009, Indiana estimated an overall savings of $11 million — 27% of its winter budget.Interested in joining?
