Defining the Problem
Police Accident Reports
Data Management and Coordination
Analytic Techniques
![Page 12: Transportation leadership you can trust. presented to Healthy Regions, Healthy People Policy and Research Symposium Series presented by Susan B Herbel,](https://reader036.fdocuments.us/reader036/viewer/2022081603/56649f1d5503460f94c33ee7/html5/thumbnails/12.jpg)

Is the incident an accident?
Damn
![Page 13: Transportation leadership you can trust. presented to Healthy Regions, Healthy People Policy and Research Symposium Series presented by Susan B Herbel,](https://reader036.fdocuments.us/reader036/viewer/2022081603/56649f1d5503460f94c33ee7/html5/thumbnails/13.jpg)

Addressing the Problem
Explicit Planning Factor
• AASHTO Greenbook and MUTCD
• Assumption: projects are “safe and efficient”
Limited solution sets
• Independent infrastructure projects
• Hazard elimination and rail grade crossing programs
• Behavioral projects (Section 402)

How new is aggressive driving?
1968 Parry. Aggression on the Road
1971 Whitlock. Aggression responsible for 85% of road crashes in England
And before?

Summary
Serious public health problem
Multivariate risk factors; hence, collaboration
New approaches required
Standard, “one size fits all” solutions nonexistant
Changes in organizational priorities are required.

What Do We Need to Worry About?
Decision Making Structure
• Who’s making the rules? Politics vs. Technical Experts
• “Congestion trumps safety every time.”
• “The road builders always win.”

Are we ahead of where we were 30 years ago?
Many issues are recurring, but we deal with them using more sophisticated methods.
While the driver has not evolved much since the creation of the first motor vehicles, the vehicles and roadways have.
The challenge now: application of knowledge gained in understanding behavior in the context of the old systems to the new and rapidly evolving ones.
Prof. David Shinar, Ben Gurion University
