Sketch Plan Methodology

4 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 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

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

8 2 Goals – 2 Methodologies 1 st Goal: Develop ITS Solutions by Corridors Criteria ITS Projects appropriate for each corridor 2 nd Goal: Prioritization Process Criteria ITS Projects appropriate for all the corridors By Corridor Meta Module

9 Identify District Priority Management Corridors for further developing a Corridor Management Vision (Quantitative and Qualitative) Identify Statewide Significant Corridors (Connections 2030, SAMP) 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.

10 Identify Region Priority Management Corridors for further developing a Corridor Management Vision (Quantitative and Qualitative) Identify Statewide Significant Corridors (Connections 2030, SAMP) 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 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.
