Background
  • Lake County
  • 24 x 20 mi area
  • Population 690,000
  • 52 municipalities
  • Congestion
  • No freeways
  • Limited 4-lane arterials
  • Transportation controversies

3
PASSAGE Goals
  • Countywide
  • 1. Improved signal system coordination
  • 2. Enhanced real time traffic monitoring
  • 3. Improved incident/event management

4
Benefits
  • Time savings to motorists from
  • Improved signal system coordination
  • Get more greens
  • Better real time traffic monitoring
  • Drivers have better information
  • Improved event management
  • Someone takes corrective action

5
Two Opportunity Factors

  • Fill in existing gaps (14 mi new)

14
2. Traffic Signals in Phase 1A
  • On the backbone
  • 95 IDOT
  • 44 County
  • 6 Municipal
  • 145 Total
  • Others remain dedicated or dialup
  • Normal project network expansion

15
4. Initiate Highway Advisory Radio
  • 3 sites to start
  • I-94 focus
  • (at interchanges)
  • Synchronized
  • Automated message generation
  • Text-to-speech conversion
  • HAR signs- 1620 AM

16
4. Initiate Highway Advisory Radio
17
5. Initial CAD interface
911
  • Sheriff Computer Aided Dispatch system
  • 911 cellular calls
  • Filters applied

18
5. Initial CAD interface
19
6. Expanded Video Camera Use
  • Incorporating 27 PTZs on backbone
  • Adding 5 new PTZs
  • Others remain dialup
  • Normal project video expansion

20
7. Initiate Dynamic Message Signs
  • 3-Portable, side road mounted
  • Use for some incidents
  • Automated message generation

21
8. Initial GCM link
  • Gary-Chicago-Milwaukee Gateway
  • Regional link
  • Via IDOT fibers along Tollway
  • IDOT Offices

22
9. Advanced Transportation Management System
  • ATMS central software brains
  • Makes everything work together

23
9. ATMS
  • Integrated congestion management
  • Operator interface
  • GIS integration
  • Failure management
  • Maintenance management
  • Signal internal paging (staff)
  • Integrated incident management
  • Web page broadcast
  • Arterials Tollway

24
9. ATMS
  • Map-based Operations
  • Monitor real-time traffic conditions from the map
  • Light, medium, heavy or alarm heavy traffic
  • Display traffic signal system and ITS devices
    with active status
  • Dynamic layering
  • Click on icon to control field devices

25
9. ATMS
  • Field Device Control
  • Signal system interface
  • CCTV control
  • HAR
  • DMS
  • Monitor RWIS

26
10. Event Management
  • Incidents
  • Planned lane closures
  • Unplanned lane closures
  • Special events
  • Weather events

27
11. Congestion Management

39
Lake County Board Strategic Plan
  • Enhance the development and expansion of an
    efficient and effective transportation system
  • .Also a Federal initiative

40
Consequences of No Action
  • Loss of opportunity to provide yearly time
    benefits to motorists through
  • Improved signal system coordination
    12.3million/year
  • Better real time traffic monitoring
    4.7million/year
  • Improved event management
    million/year

  • 17 million/year

41
1. Fiber Optic Network
  • Phase 1 (AB) Deployment
  • 1 million investment in fiber infrastructure
  • 1 million investment in electronics
  • Mesh topology 4 redundant paths and spurs

42
10. Event Management
  • ATMS will support three methods of generating a
    response plan
  • System-generated
  • Select from a plan library
  • User-generated

43
TMC Facility
44
Benefits Lake County Passage
