Winter Maintenance Winter Maintenance ChallengesChallenges• 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

MDSS Basic FunctionsMDSS 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

Project ObjectivesProject 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

Research TasksResearch 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

Research Tasks (continued)Research Tasks (continued)

• Propose high-level functional and user requirements for an operational MDSS and architecture, identifying:Some can be met immediatelySome 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

Research Tasks (continued)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

Research Tasks (continued)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
