1 presented to Wisconsin Department of Transportation - Northwest Region presented by Christopher Hedden and Brian Scott Cambridge Systematics, Inc. and SRF Inc. 10/15/07 Traffic Operations Sketch Plans Corridor Sketch Plan Methodology – Update to the Regions

2 1 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 2 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 SRF Dave Kreitzmann - WisDOT SEH Joanna Bush - WisDOT Jacobs - E&K

4 Sketch Plan Methodology

5 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 5 Interviews 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

7 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

8 7 What should the SPT NOT Do? Do not create a mechanism which prolongs the project development timeline

9 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

10 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.

11 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. Outside of Corridor Management Workgroup Restart Process ITS Sketch Planning Methodology 1.Recommended ITS Solutions/Projects by Corridor 2.Prioritization By Corridor Relevant Criteria

12 11 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.

13 12 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. Integration of operations into corridor planning begins at this phase.

14 13 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.

15 14 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
