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
• System Preservation Theme
![Page 8: Presented to Wisconsin Department of Transportation - Northwest Region presented by Christopher Hedden and Brian Scott Cambridge Systematics, Inc. and](https://reader034.vdocuments.net/reader034/viewer/2022052603/56649e375503460f94b274ef/html5/thumbnails/8.jpg)

What should the SPT NOT Do?
Do not create a mechanism which prolongs the project development timeline

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
