2. Presentation Outline History of Integrated Corridors in Wisconsin Zoo Interchange Reconstruction Transportation Management Plan Working Together/Decision Making Process Integrated Corridor Management Learning Segment Questions
3. Brief History of Integrated Corridors in SE Wisconsin Integrated corridor efforts began mid 1990’s Goal of integrating operations along arterials where multiple jurisdictions owned signals Significant efforts to establish a multiagency corridor Collaborative operations by multiple agencies – better in theory than real life For the I-94 North-South project a traffic responsive signal system was implemented For the I-94 East-West project signal timings were provided by DOT to the municipalities
4. New Approach for the Zoo Interchange Reconstruction Past experience suggested the need for a new approach to integrated corridors Zoo Interchange serves as the hub of the freeway network in the Milwaukee metro area Reconstruction would impact over 350,000 motorists per day Expanded capacity on several local arterials to address existing capacity constraints
5. Gateway to Milwaukee, largest urban center in state of Wisconsin Access to the regional medical center, tourism, jobs and education Neighborhoods and thriving communities Zoo Interchange
6. Zoo Interchange ConstructionSignificant Challenges Core of the interchange – long term closures Mainline - keeping traffic moving and Milwaukee open for business Railroad bridges – avoiding detours of rail traffic, impacts to freeway operations during construction Keep local street system operating
7. Transportation Management Plan (TMP) Staging Decisions Consider 15-minute delay guideline & project schedule constraints to determine: Lane closure time restrictions Temporary bridges or widening Temporary travel lanes or use of shoulder Ramp/road closures Then consider strategies to manage delay
8. WisDOT Working Together Zoo Interchange Reconstruction (PDS) Design Construction Traffic Management Public Information Bureau of Traffic Operations Traveler Information Incident Management Special Events State Traffic Operations Center Procurement Southeast Region Traffic Operations Traffic Signals Traffic Signing
9. Integrated Corridor Management (ICM) Key Component of the TMP Strategies Arterial and Freeway Operations 9 entities own a total of 156 traffic signals Needed to Enhance communications Enhance corridor throughput Improve safety and mobility
10. ICM Goals Optimize corridor operations versus individual networks Maximize available capacity through the corridor Improve travel time reliability and predictability Manage congestion Provide traveler information to improve decision making
11. Purpose of ICM Direct - address geometric, capacity and safety issues during Zoo Interchange reconstruction Indirect – reduce driver frustration, improve perception of DOT and municipal partnerships Integrate better traffic management functions within the project area for reconstruction and beyond

14. How did we select ICM priority corridors? Forecasted construction diversion – anticipated alternate routes Parallel routes Existing operations – volumes and levels of congestion Future conditions – growth patterns and projected volumes Connections between local arterials and freeways
