Background Lake County 24 x 20

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… 1. Improved signal system coordination… “Get more greens” 2. Better real time traffic monitoring… “Drivers have better information” 3. Improved event management… “Someone takes corrective action” 4

Two Opportunity Factors Lake County’s good fortune: 1. Institutional Arrangements 2. 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 – Eagle – Unknown or Proposed 186 96 153 • Local Municipalities – Econolite – Eagle – Other 51 15 16 661 signals total 7

Institutional Arrangements • Two major players – IDOT – County • Only 12 supplemental players 8

Funding Phase 1 A 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 1 A includes… 11

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

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 1 A • 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 • 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

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

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 • • • 25 Signal system interface CCTV control HAR DMS Monitor RWIS

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 1 A – 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 1 A still under development 80% paid out – Phase 1 A coverage • Not the whole county • Not equivalent coverage areas • Other Phases to follow 33

The Name… Lake County PASSAGE • Program for Arterial Signal Synchronization and Tr. Avel Guidanc. E • Implementation Phasing Plan (IPP) completed • Phase 1 A 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: – Better real time traffic monitoring: – Improved event management: $12. 3 million/year $ 4. 7 million/year $ + 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

10. Event Management ATMS will support three methods of generating a response plan: 1. System-generated 2. Select from a plan library 3. User-generated 42 Event Details DMS Operator Actions Operator Freeway Actions CMS ATMS Response Plan Traffic Signal HAR (notepad) ATIS Freeway Advisories CMS
