Winter Maintenance
Challenges
4
• 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
MDSS Basic Functions
5
• 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
Project Objectives
6
• 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
Research Tasks
7
• 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
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
8
• 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,
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
9
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
