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

8

What should the SPT NOT Do?

Do not create a mechanism which prolongs the project development timeline

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
