Sketch Plan Methodology
Approach to Developing Methodology
Based on WisDOT planning
perspective
•
Central and Regions
Integrate or utilize current processes
as much as possible
Planning/Programming/Budget Scan
•
Interviewed Central Office and
Research
•
Researched key current processes
− Corridor Approach

Initial Findings
Strong support for Operations/ITS
Criteria development seen as most critical
step
•
Statewide
Unanimous support for a mechanism by
which Operations/ITS needs can be
identified across the state
•
Prioritized list
•
Guidelines for implementation (field device
density and type)
Operations/ITS needs to be reflected at the
policy level
•
6
System Preservation Theme
What should the SPT NOT Do?
Do not create a mechanism which
prolongs the project development

1st Goal: Develop
ITS Solutions by
Corridors

Identify
Statewide Significant Corridors
(Connections 2030, SAMP)
Identify
District Priority Management Corridors for further
developing a Corridor Management Vision
(Quantitative and Qualitative)
Develop a Corridor Management Vision
In creation of a vision, the same “factors” are used, however
District Information will account for more details and
regional/local issues. Community involvement would be part of
this step.
Identify and select Strategies and Tools to
achieve the Corridor Management Vision
Implement the Corridor Management Vision
Update and revise the Corridor Management
Vision and Implementation Strategies as needed.

Sketch Planning Methodology Criteria
Used 42 initial criteria as starting point
• Strive for consistency with main
Corridor Planning Methodology
• Realistically measure the effectiveness
of alternatives
• Allow operational alternative to be
compared
− With each other
− With other types of improvements
− Drives toward a hybrid approach that
includes traditional as well as
operational metrics
• Data readily available
− Quality controlled
− Regularly updated
• Results can be easily summarized
