Why Should You Have Accessibility to Crash Data?
Because…..• Improvements in producing high quality cause-of-death
data are crucial for improving health and reducing preventable deaths. (World Health Organization)
• It removes the guesswork and efficiently places resources where they can best be used
• It can assist in receiving federal funding for education, engineering and enforcement projects
• It assists in reducing crashes, fatalities and serious injuries
• It is your Data
• It Saves Lives
Can You Explain It Without the Crash Report? Must be a Fixed Object Crash
Typical Data Analyzed from Crash
Report
(Not a Complete List)
• Crash Type• Primary Cause• Secondary Cause• Weather condition• Traffic Control Device• Lighting Condition• Event Location• Vehicle Type• Alcohol Use• Road Surface Condition• Number of Lanes• Injury Classification
Crash Data Analysis• Understanding “Why” there is a
problem
• Leads to beginning stages of Problem Identificationo Mapping of crash locationso Summarizing of all data elements
• Avoid making assumptions
Very Important !Crash Report
Narrative/Diagram
PROBLEM IDENTIFICATION
Ran off road to the left
and overturne
d
Lost control in the snow
and crossed
into opposing lane in
front of a semi
Ran off the road
to the left and hit a
utility pole
Swerved to miss a deer and ran off the road to
the left striking a
utility pole
SB pickup ran a stop sign and
struck eastbound
pickup
Crash report
not found
WB vehicle veered from its
lane
Dropped a wheel off on
the right, overcorrected,
ran off the road to the
left, overturned
Lost control
and crossed
into opposing
lane; head on
SB vehicle missed a stop sign and hit
passing WB semi
Motorcycle dropped off to the
right, overcorrec
ted and overturned
on pavement
SUV dropped wheel off to
the right, lost control, and overturned
on pavement
WB pickup dropped a
wheel off to the right,
overcorrected, ran off to the left and hit a
house
EB car dropped a
wheel off to the right,
overcorrected, ran off to the left and overturned
EB car lost control and
slid sideways in front of opposing
traffic
WB SUV crossed
pavement off to the south
side, re-entered EB
lane, and hit EB pickup
truck
EB car hydroplaned in water at RR
underpass and left road to the left, hitting the curb
SB van pulled from stop in front of EB
pickup
And Yes sometimes they are Entertaining…..but Rarely!
• Coming home I drove into the wrong house and collided with a tree I don’t have!
• The other car collided with mine without giving warning of its intent!
• I collided with a stationary truck coming the other way.
• In my attempt to kill a fly, I drove into a telephone pole.
Eliminate Assumptions in Data Analysis
• Easy to assume cause based on “data” alone
• The Narrative on the crash report from the Officer at the scene is extremely important
• Verify cause through use of narrative/ diagram
• Don’t Stop There -- Eliminate as many Assumptions as possible
• Do Site Reviews
Can you get copies of these or
just Data generated from them?
FHWA/IDOT Process Review
• IDOT/FHWA meet once a year to Select Process Review Topics
• Selection of topics should be based on real or perceived opportunities for improvement
• IDOT/FHWA recommend topics for review
• Final topic selection based on consensus of both IDOT/FHWA management
Availability and Use of Crash Data Process Review
Assess the AVAILABILITY and ACESSIBILITY of:
Illinois Crash Reports and Data
for the purpose of: IMPROVING problem identification and
safety countermeasure selection

Illinois Law
• 625 ILCS 5/11-411 “Accident Report Forms”
o IDOT has duty to prepare and supply crash report forms to police agencies
o The written reports must have detailed information in accordance with standards.
o (Pub. Act 78-255)
Illinois Law (cont.)• 625 ILCS 5/11-408 “Police to report motor
vehicle accident investigations” (Pub. Act 96-1147, eff. 7/21/10)
o Police must submit all crash report to IDOT
o Upon request, the Department shall furnish copies of its written crash reports to federal, state, and local agencies that are engaged in highway safety research and studies. (effective date July 2010)
Illinois Law (cont.)
• 625 ILCS 5/11-412 “Motor vehicle accident reports confidential”
o All required written accident reports shall be for the confidential use of the Department and SOS
o The Department may furnish copies of its written accident report to “federal, State, and local agencies that are engaged in highway safety research and studies (Pub. Act 95-757, eff. 7/25/08)
Illinois Law (cont.)

(Pub.Act 95-757, eff. 7/25/08)
o Department shall tabulate and may analyze all written motor vehicle accident reports and shall publish annually or at more frequent intervals statistical information based on as to the number and circumstances of traffic accidents.
Draft Observation/Recommendation
• Observation: The language of four IVC statutes relating to
crash reports and data has been interpreted in different ways over the years, is confusing and leaves gray areas for interpretation
• Recommendation: Ensure all safety users have adequate
accessibility to complete crash data for safety.
Draft Observation
• Observation: There seems to be a lack of formal IDOT policies and guidelines regarding the use
of crash reports, there dissemination, review and updating
Draft Recommendation
• Create policy and guidelines to include:
o What crash “data” or “reports” can be released
o Define what information on crash report is “personal” and “confidential” and what can/cannot be released
o Clarify who can receive data including the media, general public, researchers, consultants etc. and under what circumstances
o Create guideline for regular review and updating of crash report form
o Adhere to a strict schedule for completion of year end crash data within a certain time period
o Create provisional data use policy
Draft Observation
• Factors such as lack of personnel, technical knowledge, time and difficulty accessing their own data, problem identification through the review of crash reports is difficult to produce for many county, city and state agencies.
Draft Recommendation
• Provide user friendly access to crash report images, mapped locations of crashes and query system to facilitate a more efficient and timely review of crash data
• Include Enforcement, EMS, Education and Engineering
Draft Observation
• Many agencies commented that they were not aware of many techniques of crash data analysis and would like more training if it were available.
Draft Recommendation
• Create and provide training for crash data analysis to County, City, State agencies in the Education, EMS, Enforcement and Engineering fields for better problem Identification and countermeasure selection.
Best Practice
• IDOT District offices generally agree that they have good access to:
o Crash Report Images
o Crash Data
o GIS Maps
Recommendation: Review possible access of these systems for the rest of the data users.
Illinois Statistics in 2012
• 956 People Died on Illinois Roadways
• 274,111 Crashes
• 83,768 Total Injuries
• 12,401 “A” Type Injuries (Incapacitating)
o Why?
o Where?
o When?
o How Do We Fix It?
