slide 2: Overview

  • Michigan's I-94 Corridor
    • GLRTOC
    • Partners & Mission
    • Geographic Area
    • Work Zone Coordination

slide 3: MDOT Structure/I-94 Corridor

Map depicts the I-94 corridor from Caloma, Michigan, through MacComb-St. Clair, Michigan.

slide 4: 2011 Predicted Performance

Map of the I-94 corridor with 2011 predicted performance for three segments: 1. Indiana Border to I-69 (15 minutes max), 2. I-69 to I-75 (15 minutes max) and 3. I-75 to Canada (max 10 minutes). For the first segment, three projects were planned for 15.5 miles of WZ, 3.3 minutes TTD in peak, and 6.9 minutes TTD in off-peak. For the second segment, 8 projects were planned for 32.8 miles of WZ, 13.0 minutes TTD in peak, and 14.1 minutes TTD in off-peak. For the third segment, 3 projects were planned for 14.3 miles of WZ, 3.8 minutes TTD in peak, and 14.4 minutes TTD in off-peak.

slide 5: Average Delay per Vehicle

Graph shows average delay for 2011 for the I-94 corridor broken out by segment and by month. Segment 2 (I-69 to I-75) shows the greatest delay for all months except March and April, in which Setment 1 (Indiana to I-69) carries the greatest delay.

slide 6: Main Posted Speed Limits 2011

Graph shows the percentage of traffic operating at posted speeds by week from April through November for each municipality in the region.

slide 10: GLRTOC Strategies

  • Three Strategic Focus Areas
    • Efficient freight operations
    • Reliable mobility
    • TIM / ETO

slide 11: Annual Work Zone Preview

  • LMIGA has been doing this for years for the Chicago region
  • Among the first efforts of GLRTOC
  • Held first week of February in Chicago

slide 13:

Screenshot of an ArcGIS-generated map that allows the user to select work zones on GLRTOC corridor routes or work zones outside the corridors. By selecting the work zone icon on the map, popup boxes appear describing teh location, direction, dates, type of work, etc. The user may also add or update work zone information.

slide 14: GLRTOC MCOM Award

  • Multi-State Corridor Operations & Management award for:
    • Center to Center Communications
    • Smart Work Zone Coordination

slide 15: Smart Work Zone Coordination

  • Three tasks:
    • Annual work zone preview enhancements
    • Work zone mapping application
    • Work zone performance monitoring

slide 16: 2. Work Zone Mapping Application

slide 18: 3. Smart Work Zone Monitoring

  • Pilot test segment is I-39/90 between Madison, WI and Rockford, IL
  • 65-mile mostly rural corridor
  • Minimal detection available
  • Three agencies
  • Multiple medium and high impact work zones
