Olson v Baker Driver Perception/Response Times
Posted: Mon Nov 09, 2015 1:06 pm
Q: I would like to gather opinions on the merits or applicability in casework of perception-reaction time as defined by Paul Olson in "Forensic aspects of driver perception and response" (2010) versus that by J Stan Baker in "Perception and reaction in traffic crashes". I was told that Baker's definition had an advantage in reducing ambiguity regarding which point a hazard can be considered perceptible to a driver. However I am skeptical as definitions of PRT include similar components (however named or categorized) which need to be accounted for. When PRT starts is often quite a challenge.
A: Since we've been buried in preparing and releasing our msmac3D software we've been somewhat out of the loop on the most recent developments in driver preception/reaction studies. Particularly now with many studies which incorporate built in video systems so actual crashes (as opposed to laboratory or staged settings) are being investigated.
For example, SAE 2005-01-0426 Factors that Influence Drivers' Response Choice Decisions in Video Recorded Crashes.
We recommend you contact Jeffrey Muttart and/or Crash Safety Research and/or Crash Safety Solutions.
They specialize in driver perception/response and all things driver related and so might point you to papers which may include reviews and comparisons of Olson vs Baker.
I will also drop Jeff an email and post up any response i get from him on your question.
