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…

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”

5

Two Opportunity Factors

Lake County’s good fortune:

1. Institutional Arrangements

2. Funding

6

Institutional Arrangements

Measured by number of signals:

435 IDOT

144 County

82 Municipal (12 of 52)

661 signals total

7

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

8

Institutional Arrangements

• Two major players– IDOT– County

• Only 12 supplemental players

9

FundingPhase 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

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

• 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

– 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

24

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

9. ATMS

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

• 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

28

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

29

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

30

ITS Technologies

• All housed in Traffic Management Center (TMC) in Libertyville:– Building addition

• One story, 4400 sq ft

• Houses traffic section

31

TMC Facility

32

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

33

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

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 (A&B) Deployment

• $1 million investment in fiber infrastructure

• $1 million investment in electronics

• Mesh topology – 4 redundant paths and spurs
