WHAT HAPPENS WHEN …..
Reasons for Incident Management
• It improves highway safety
• It reduces traffic congestion
• It reduces emissions and enhances environmental conditions
Keys to Incident Management
• Notification• Detection• Confirmation• Communication • Response• Site
management• Clearance
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

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
Primary Focus Is On Safety
• Protecting the responders
• Attending to the injured
• Safe travel through the scene
On Scene Traffic Control
• Inherent danger while working adjacent to live traffic
• Need to establish a safe working area
• Provide a temporary work zone
INITIAL PHASE OF TRAFFIC CONTROL
FORMAL LANE CLOSURE
UN-NECESSARY LANE CLOSURE
Clearance
•Restore traffic flow–Safely move traffic around
incident–Re-open lanes without delay –Average, 219,000 incidents- Average clear time 34 minutes
Three “Cs” for a Traffic Incident
• Communication
• Coordination• Cooperation
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
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)
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
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
