  3. Research Contractor • Meridian Environmental TechnologyGrand Forks, ND • Bob Hart • Leon Osborne • John Mewes • many more

  4. Winter Maintenance Challenges • Rising expectations of traveling public and commercial carriers • Constrained agency funding and staffing • Reliable, timely, specific reports of conditions difficult to obtain • Some weather conditions are difficult to forecast • Pavement response to weather conditions and maintenance treatments is not well established • Effects and effectiveness of innovative maintenance treatments not well understood • Retiring maintenance staff replaced by less experienced workers

  5. MDSS Basic Functions • Assess current road and weather conditions • Provide time- and location-specific weather forecasts along transportation routes; • Predict road conditions under forecast weather and candidate maintenance treatments • Notify state agencies of approaching conditions and suggest optimal maintenance treatments • Evaluate prediction reliability and maintenance treatment effectiveness

  6. Project Objectives • Assess need, benefit, and receptivity to MDSS in participating DOTs • Define functional and user requirements for an operational Maintenance Decision Support System • Build and evaluate an operational Maintenance Decision Support System • Improve the ability to forecast road conditions in response to changing weather and applied maintenance treatments

  7. Research Tasks • Meet with the project’s technical panel • Critically evaluate results of the federal MDSS project • Interview front-line and mid-level maintenance supervisors to identify and prioritize needs • Assess participating states’ current and near-term capability to report current roadway conditions and track maintenance activities on specific routes • Assess institutional receptivity to maintenance management decision support

  8. Research Tasks (continued) • Propose high-level functional and user requirements for an operational MDSS and architecture, identifying: • Some can be met immediately • Some will require research • Construct prototype MDSS incorporating those requirements that can be immediately satisfied. • Prepare plan for pilot deployment and evaluation of the basic prototype MDSS in a multi-state test region spanning portions of North Dakota, South Dakota, and Minnesota

  9. Research Tasks (continued) • Deploy prototype MDSS in multi-state test region and evaluate performance during the winter of 2003-2004 • Develop and test system new components that need fundamental research, incorporating ongoing and emerging technology • Recommend needed improvements and design modifications and identify operational limitations requiring additional research and development

  10. Research Tasks (continued) • Make system improvements, deploy an improved prototype MDSS in state agency offices in the multi-state test region, and evaluate performance winter of 2004-2005 • Final report • Executive presentations and electronic copies

  11. 3-State Test Area

  12. Issues • Availability and update of federal software • Diverse practices among 5 participating states • Effects of some parameters unknown • Treatments • Traffic • Wind/drifting • Location-specific weather forecasting • Feedback of evolving road conditions • Need for simplicity • Institutional receptivity • Funding
