Presentation Transcript

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

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

  3. 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”

  4. Two Opportunity Factors Lake County’s good fortune: • Institutional Arrangements • Funding

  5. Institutional Arrangements Measured by number of signals: 435 IDOT 144 County 82 Municipal (12 of 52) 661 signals total

  6. Institutional Arrangements Existing and proposed signals: • LDOT • Econolite 144 • IDOT • Econolite 186 • Eagle 96 • Unknown or Proposed 153 • Local Municipalities • Econolite 51 • Eagle 15 • Other 16 661 signals total

  7. Institutional Arrangements • Two major players • IDOT • County • Only 12 supplemental players

  8. Funding Phase 1A cost = $6.3 million • 42% federal ITS earmarks • 16% special federal earmark • 42% county local match In-kind state assistance • IDOT • ISTHA • GCM Corridor

  9. What is in Lake County PASSAGE? i.e. What Intelligent Transportation System Technologies are being used?

  10. ITS Technologies • Briefly, Phase 1A includes…

  11. 1 Fiber optic network 2 Connect traffic signals 3 Install TSS 4 Initiate HAR 5 CAD 6 Video camera 7 GCM link 8 DMS 9 ATMS 10 Event management 11 Congestion management 12 Traveler info 13 Maintenance management ITS Technologies

  12. 1. Fiber Optic Network Start fiber backbone network (79 miles) • Gigabit Ethernet • Mesh topology • Redundant paths • Fault tolerant • Fill in existing gaps (14 mi new)

  13. 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

  14. 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

  15. 4. Initiate Highway Advisory Radio

  16. 5. Initial CAD interface 911 • Sheriff Computer Aided Dispatch system • 911 cellular calls • Filters applied

  17. 5. Initial CAD interface

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

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

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

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

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

  23. 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

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

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

  26. 11. Congestion Management • Real-time • Signal timing changes • Real-time traveler information (DMS and HAR) • Advanced congestion management • Support for timing optimization • Data collection and interface to Synchro capacity software • Support capacity analysis

  27. 13. Maintenance Management • View and log signal system failures • View and log ITS device failures • Provide logging of maintenance activities • Track open maintenance items • Page maintenance personnel

  28. 12. Traveler Information • Provide for real-time web map display • Include incidents and planned events • Provide interface to the GCM gateway • Traffic data • Event details • Eventually signal coordination

  29. ITS Technologies • All housed in Traffic Management Center (TMC) in Libertyville: • Building addition • One story, 4400 sq ft • Houses traffic section

  30. TMC Facility

  31. TMC Staffing Phase 1A • 2 TMC operators • 5:30 am – 8:00 pm coverage • Hands on peak periods Monday thru Friday • Actively monitor traffic conditions and status • 6:30 - 9:00 am • 3:00 - 6:30 pm • IDOT Office Space

  32. ITS Technologies Caveats • Phase 1A still under development-80% paid out • Phase 1A coverage • Not the whole county • Not equivalent coverage areas • Other Phases to follow

  33. Thanks to… • County Engineer • Martin Buehler P.E. • Consultant • NET… Joseph Brahm, P.E. • IDOT • ISTHA • Federal Reps and FHWA

  34. Questions?

  35. Direct Fiber Communication Equipment used

  36. Direct Fiber Communication Equipment used

  37. The Name… Lake County PASSAGE • Program for Arterial Signal Synchronization and TrAvel GuidancE • Implementation Phasing Plan (IPP) completed • Phase 1A underway

  38. Lake County Board Strategic Plan “Enhance the development and expansion of an efficient and effective transportation system…” …….Also a Federal initiative

  39. 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

  40. 1. Fiber Optic Network Phase 1 (A&B) Deployment • $1 million investment in fiber infrastructure • $1 million investment in electronics • Mesh topology – 4 redundant paths and spurs

  41. Event Details DMS HAR HAR Operator ATMS ATMS (notepad) Actions Response Response Plan Plan ATIS Operator Freeway Freeway Advisories Actions CMS CMS Traffic Signal 10. Event Management ATMS will support three methods of generating a response plan: • System-generated • Select from a plan library • User-generated

  42. TMC Facility

  43. Benefits – Lake County Passage 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”
