2. Agenda • Introductions • Sketch Plan Update – Progress to Date • Methodology and Criteria • Approach • Criteria • Data Collection, Analysis, and Synthesis • Draft Regional Results • Regional Smoothed Data • Regional Corridors • Next Steps

3. Project Overview • 23 month project • Initiated July 06 Corridor Planning Methodology for Traffic Operations Todd Szymkowski – TOPS Cambridge Systematics Ramp Control and Surveillance Travel Warning and Information Systems Traffic Signal Systems Marie Treazise - WisDOT Dave Kreitzmann - WisDOT Joanna Bush - WisDOT SRF SEH Jacobs - E&K

4. Sketch Plan Methodology

5. 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

6. DTIM Mark Wolfgram Southeast Donna Brown Bob Anderson Southwest John Vesperman Dan Pruess Northwest Gary Bruner Planning Aileen Switzer Jennifer Murphy Budget Casey Newman Karl Kuecker Interviews

7. 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

9. 2 Goals – 2 Methodologies ITS Projects appropriate for each corridor ITS Projects appropriate for all the corridors 1st Goal: Develop ITS Solutions by Corridors Criteria Criteria Meta Module 2nd Goal: Prioritization Process By Corridor

10. 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 thisstep. 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.

11. Identify Statewide Significant Corridors (Connections 2030, SAMP) Outside of Corridor Management Workgroup Identify Region Priority Management Corridors for further developing a Corridor Management Vision (Quantitative and Qualitative) Relevant Criteria ITS Sketch Planning Methodology Develop a Corridor Management Vision In creation of a vision, the same “factors” are used, however Region Information will account for more details and regional/local issues. Community involvement would be part of thisstep. • Recommended ITS Solutions/Projects by Corridor • Prioritization • By Corridor Identify and select Strategies and Tools to achieve the Corridor Management Vision Restart Process Implement the Corridor Management Vision Update and revise the Corridor Management Vision and Implementation Strategies as needed.

13. Integration of operations into corridor planning begins at this phase.

15. 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 Corridor Planning Criteria

16. Final Sketch Plan Criteria
