What is Hazard Perception?
BrightFleet.com – “Reducing Collisions by Improving Drivers Hazard Perception”
“Scanning and perceiving potentially dangerous situations in time, and being able to predict the way in which traffic
situations will develop...in order to take action to avert the danger.”
Institute for Road Safety ResearchLeidschendam, the NetherlandsFebruary 2010

Detection of looming hazard
Threat appraisal
Selection of actions to avert hazard
Implementation of actions chosen

Detection of Looming Hazards
What do drivers look at while driving?
How do they scan the traffic situation?
Are they looking for hidden hazards?
BrightFleet.com – “Reducing Collisions by Improving Drivers Hazard Perception”
Threat Appraisal
Evaluating seriousness of hazard.
Predicting threat of collision.
BrightFleet.com – “Reducing Collisions by Improving Drivers Hazard Perception”
Selection of Action to Avert Hazard
Finding a safe “out” to avoid collision.
Considering risks of actions taken.
Determining best action to take.

Implementation of Action to Avoid Crash
Braking, Slowing, Changing Lanes,Signaling

These four processes are not independent of each other, but instead
are evaluated together.

Drivers “feel” hazardous situations when they perceive them.

This emotional response to “near miss” events is believed to form a lasting impression in the drivers memory.

These memories form an unconscious influence during complex hazard
detection and threat appraisal scenarios.

Computer Based Training
The most effective hazard perception training involves presenting drivers with
images and videos taken from the drivers perspective and asking the
driver to identify the hazards as they appear.

Drivers are asked to identify hazards, either by identifying explicit hazards as they appear, or by predicting potential hazards based on the events unfolding
before them.

Stress of training adds to retention of the training material.

Driving Simulators
Hazard perception training using active driving simulators is still in its infancy, with several systems currently being
developed.

Regular Driving Lessons
Hazard perception can be trained during regular driving lessons if the trainer is “thinking out loud” about
hazards both actual and potential during the training.

Hazard Perception Evaluation
Evaluating a drivers ability to perceive hazards can be done quickly across an
entire company of drivers using specialized web-based exam. Tailored
training can be assigned.

Self Assessment
Questionnaire that asks to self-identify beliefs about driving, risk taking behaviors, and driving record.

DMV or DOT Driving Record
Review MVRs for your drivers to get a sense of risk.
