1. 1 Arterial AMS Deployment Case Study By Joseph Brahm (847) 925-0120

2. 2 Presentation Agenda wNot focused on evaluation of centralized signal systems wMany other considerations –Real time information Collection –Multi-jurisdictional consideration –Supporting other internal agency functions –Deployment with limited resources –Support for traffic engineering –Arterial response plans wReview through sample deployment

3. 3 Introduction to Lake County Passage wLocated in northeastern Illinois, in the heart of the Gary- Chicago-Milwaukee (GCM) ITS Corridor, wPopulation of 650,000 and is expecting to grow to near 850,000 by 2030. wFreeways and arterials are experiencing increasing congestion. wLake County Division of Transportation, Illinois Department of Transportation (IDOT), Illinois State Toll Highway Authority (ISTHA), the regional Emergency Telephone System Board (ETSB) and other local municipalities. wThe Passage concept was developed to more effectively manage the demands on the multi-jurisdictional transportation network.

5. 5 System Deployment Considerations Typical components with new twists

6. 6 External Interfaces wTypically multiple jurisdictions to consider –Cities, Counties and States –Signal operations and Maintenance –Communications infrastructure –Law enforcement –Emergency response wWant to help not annoy other partners wShared systems and automated interfaces really help

7. 7 Data Acquisition wCommunications –More options now wTraffic Data –System Detectors Location All unique –Video Detection –CCTV –Now Probe Data

8. 8 Data Acquisition wEvents –Coordination with emergency response critical –CAD interface or terminal –Much more than just detection –Construction and maintenance activities –Special events

9. 9 System Configuration wWhat is congestion on an arterial? –Location specific Many factors contribute »Speed limit, detection type, detection location –Settable congestion level bands Based on nominal speeds wWhen do you trigger an alarm? –Alarm heavy congestion Must be by location and time of day and day of week Smooth out signal effects

11. 11 Map and Web Consideration

12. 12 Event Management wAutomated response plans –System generated response plans –Or from a library –Or by the user ATMS Response Plan Freeway CMS Operator Actions HAR (notepad) HAR Operator Actions DMS Event Details Freeway CMS ATIS Advisories Traffic Signal

13. 13 Event Response wIncidents –Unlimited possible locations Arterials have more options than freeways Can not have fixed plan for every locations –System intelligence very helpful Combination of rules and templates CRASH AHEAD {LEFT LANE} CLOSED {PAST RTE 45} The {left lane} is closed {just past Route 45} due to a crash. {Expect delays}. {Please use an alternate route} The {left lane} is closed {just past Route 45} due to a crash. Expect delays throughout the AM peak DMS WEB HAR

14. 14 Event Response wPlanned events –Construction, maintenance Unlimited possible locations Work well with rules and template model Pre-event and active event responses On {northbound Route 45}, {just past} {Huntley Road}. Starting {September 10 th} at {10:00 PM all lanes} will be closed nightly for roadwork. On {northbound Route 45}, {just past} {Huntley Road}, {all Lanes} are closed for roadwork. Use an Alternate Route. Pre-eventActive event

15. 15 Event Response wSpecial Events –Location specific –Work well with response plan Libraries Set up DMS,HAR, WEB and signal response ahead of time –Pre-event, active event, and post event messaging –Arterial responses can be more complicated than freeway
