“To the public the worst thing is being delayed.

The second worst thing is not knowing why they’re

being delayed.”

… … State DOT Executive

Work Zone Safety and Mobility

“It is the sense of Congress that many highway projects are carried out in a way which unnecessarily disrupts traffic flow during construction and that methods need to be adopted to eliminate or reduce these disruptions.”

Section 1090 ISTEA


WZ Crashes

• Majority Occur:– Beginning of the Queue

– In the Transition Zone

• Caused By:– Excessive Speed

– Driver Inattention


““Meeting the Customer’s Needs for

Mobility & Safety

During Construction &

Maintenance Operations”


Work Zone Safety & Mobility

• Federal Rule

• Effective October 12, 2007

• State and Local Agencies

• All Types Of Projects

• Federal Aid System

WZ Safety & Mobility-IDOT Policy

Policy StatementDuring construction, maintenance, and all other activities on our highways, it shall be the policy of IDOT to provide a high level of safety for workers and the public, to minimize congestion and adverse community impacts, and to provide greater public satisfaction.


VisionReduce And Eliminate Crashes And Fatalities, And To Mitigate Congestion Due To Work Zones


Safety Goals :• Zero Worker Fatalities

• Reduce motorist fatalities in traffic-related work zone crashes by 10% each year with the eventual goal of eliminating all of these fatalities.

• Eliminate crashes, resulting fatalities, and serious injuries caused by queuing.

• 5% Annual Reduction of WZ crashes


Mobility Goals : :

• Delays Shall Not Exceed 5 Min/Mile with a Max. of 30 Minutes

• Queues Shall Not Exceed 1.5 Miles Beyond Pre-existing Queues

Work Zone Safety & Mobility

Transportation Management Plan (TMP)• Traffic Control Plan (TCP)

• Transportation Operations Plan (TOP)

• Public Information Plan (PIP)


Traffic Control Plan (TCP)

• A plan to safely guide traffic through a construction project through the use of traffic control devices and project coordination.


Transportation Operations Plan (TOP)

• A plan that consists of strategies which mitigate work zone impacts through the use of improved transportation operations and management of the transportation system.


Public Information Plan (PIP)

• A plan that consists of strategies to inform those affected road users including the surrounding community of the expected impact of a project, of changing conditions, and available travel options.


Non-Significant Projects

• Minimal Delay

• TCP Required

• PIP Encouraged

• TOP Encouraged


Significant - Short Term Projects

• Significant Route

• Work 3 Days or Less

• Develop Permitted Lane Closure Map

• TCP Required

• PIP Encouraged

• TOP Encouraged


Significant - Long Term Projects

• Significant Route as Identified on Maps

• Impact Analysis Required

• Identify Impacts and Strategies to Mitigate These Impacts

• Consider Impacts Early in Planning Phase

• Full TMP Required



• Impacts Meet Goals– Bi-Monthly Coordination Meeting

• Impacts Do Not Meet Goals– Includes Reasonable & Appropriate TMP

Strategies– “Exception to Compliance Request”– Bi-Monthly Coordination Meeting



SIGNIFICANT PROJECTS NEAR PS&E DATE

• “Exception to Compliance Request”

• Project Description

• Status of Project Letting Date

• Justification for How the Project’s PS&E Would Be Affected & Why the Exception Is Requested.


Work Zone Reviews

• Work Zone Safety and Mobility Policy Process Review

• Work Zone Traffic Control Project Review


TMP Performance Assessment

• Work Zone Crash Summary Report– Fatal Crashes – Within 10 Days

• Work Zone TMP Summary Report– Significant Projects-Long Term– Within 30 Days of Project Completion

SUMMARY REPORTS

• These reports are to be prepared in accordance with the Illinois Vehicle Code at 625 ILCS 5/11-408© and these reports shall be for the privileged use of the Department and held confidential, and shall not be used in any trial, civil or criminal.



Work Zone Crash Summary Report

• Summary of Type of Construction

• Traffic Control in Place at Time of Crash

• Traffic Conditions at Time of Crash

• Contractor’s Operations at Time of Crash

• Weather & Pavement Conditions, & Time of Day


Work Zone Crash Summary Report

• Changes Made to Traffic Control as Result of Crash

• Recommended Changes to IDOT’s Stds & Specs, Policies & Procedures Considered as Result of Crash

• Photos of Traffic Control throughout the Project Before & After Crash


Work Zone TMP Summary Report

• Project Description, Staging & Traffic Control Utilized

• TMP Strategies Utilized

• Traffic Operations Due to Work Zone

• Changes to the TMP


Work Zone TMP Summary Report

• Changes to the Traffic Control Due to Crashes Occurring Within Project Limits

• Recommended Changes to IDOT’s Stds & Specs, Policies & Procedures

Where to from here?

•Use Crash And Operational Info/Data

•Training Required

•Systematic WZ Impacts Assessment & Management
