Effective Incident Management for Illinois Tollway Safety and Traffic Flow

The Illinois Tollway has evolved since its opening in 1958, growing from 187 miles and 62,000 daily vehicles to 286 miles serving 1.4 million vehicles by 2010. With a robust incident management system, it enhances highway safety, reduces congestion, and minimizes environmental impacts. Key components include rapid notification, real-time monitoring through TIMS, and coordinated response teams. Maintenance personnel are trained as first responders, utilizing various communication channels to ensure public awareness and expedite lane clearance, with an average incident response time of just 34 minutes.

  1. MAINTENANCE & TRAFFIC OPERATION INCIDENT MANAGEMENT

  2. The Illinois Tollway - 1958 • The Tollway opens in 1958 • 187 miles, serving 62,000 vehicles a day • 8 maintenance sections • 265 bridge structures • 9 mainline toll plazas • 15 ramp toll plazas

  3. The Illinois Tollway - 2010 • The Tollway in 2010 • 286 miles, serving 1.4 million vehicles a day • 2,035 lane miles • 11 maintenance sections • 636 bridge structures • 22 mainline toll plazas • 51 ramp toll plazas

  4. TOLLWAY SYSTEM MAP

  5. SYSTEM - WIDE AVERAGE DAILY TRAVEL I90 – 301,750 Tri – 593,250 I88 – 260,970 N/S - 205,210

  6. Rule of Thumb • Every minute of lane blockage on the road can create from four to nine minutes of resulting congestion.

  7. WHAT HAPPENS WHEN…..

  8. Reasons for Incident Management • It improves highway safety • It reduces traffic congestion • It reduces emissions and enhances environmental conditions

  9. Keys to Incident Management • Notification • Detection • Confirmation • Communication • Response • Site management • Clearance

  10. Notification • Motorist report to Tollway via cell phone • Internal report via State Police or Maintenance • Media report • #999 Cellular Express Line • TIMS (Traffic Incident Management Center) • CCTV surveillance observes incident • All notifications go through Computer-Aided Dispatch Center (CAD)

  11. CAD – COMPUTER AIDED DISPATCH

  12. Traffic Operation Center TIMS

  13. TRAFFIC OPERATIONS • TRAFFIC OPERATIONS CENTER – TIMS • 5A-8P Mon/Fri (weekends as needed) • 4 console workstations • 4 TIMS Computers • 4 CAD computers • 6 video wall units • Media hotlines/email notifications • Tollway LAN

  14. Traffic Operations Cont’d. • TIMS Responsibilities • Incident detection, confirmation, assessment • Monitor and report effects of construction on traffic • Communicate to the public • Media, DMS, PCMS • Regional communications

  15. Communication • Motorist - Customer • Through 39 DMS on system • Through 49 PCMS • Through the GCM web page • E-mails to media, radio, and TV • Cross agency messaging

  16. Response • 11 maintenance locations throughout system • Responsible for 25 to 30 center line miles • From 25 to 44 full-time personnel • 7 located in Chicago; 4 located in rural areas • 24 x 7 operation routine maintenance & incident response • Significant resource base

  17. Response (cont.) • All maintenance personnel trained in traffic control and as a first responders • ISP District 15 assigned to Illinois Tollway • 60 arrow-board response units • 55 fire and ambulance agreements

  18. Response (cont.) • 36 towing and service agreements • 7Vehicle recovery agreements • Hazardous materials contracts

  19. Highway Emergency Lane Patrol HELP

  20. Highway Emergency Lane PatrolHELP (cont.)

  21. Site ManagementTraffic Control • Not to be restrictive • Be aware of the needs of others • Analyze what is needed and how to establish traffic flow • Protect the scene for all responders for duration of operations • Minimize lane blockage and mitigate congestion

  22. Primary Focus Is On Safety • Protecting the responders • Attending to the injured • Safe travel through the scene

  23. On Scene Traffic Control • Inherent danger while working adjacent to live traffic • Need to establish a safe working area • Provide a temporary work zone

  24. INITIAL PHASE OF TRAFFIC CONTROL

  25. FORMAL LANE CLOSURE

  26. UN-NECESSARY LANE CLOSURE

  27. Clearance • Restore traffic flow • Safely move traffic around incident • Re-open lanes without delay • Average, 219,000 incidents • Average clear time 34 minutes

  28. Communication Coordination Cooperation Three “Cs” for a Traffic Incident

  29. Communication • I-REACH (Illinois Radio Emergency Assistance Channel) • Various agencies can communicate together • It is a tool for assisting and locating incidents • Interactions at the scene • Post incident review • Mutual field visits to facilities

  30. I-REACH RADIO • This practice is used for emergency response communications for incidents that occur on the Tollway system • Complies with the operational concepts provided under and in support of the: • National Incident Management System (NIMS) • Unified Command System (UCS) • Incident Command System Principles (ICS)

  31. Coordination • Set-up unified command • Identify the leaders; meet face to face • Assess resources needed and available • Determines staging areas for ancillary equipment • Allow time and opportunity to get the job done • Determine efficient exit strategy mitigate the impact

  32. Cooperation • Take a team approach to incident resolution • Be aware of the needs of others • Maximize safety of the responders • Maximize the efficiency of operations • Provide highest level of service to our customers
