IDRR offers the most up to date and comprehensive sample of peer reviewed drivers’ responses ever compiled. Our sample performs as a baseline that can then be used to compare to your subject driver.
Through the software all data points are easy to obtain and will be on-point to your investigation. The source of the data is transparent and well cited.
We give you the confidence in knowing that we have the most recent data for PRT to immediate hazards. The specificity of our data covers human factors timing for leg movement, steering, braking and the influence of crash type on response times and how they range for normal drivers for each crash type.
Nightime hazards range from and could be influenced by street lighting, reflective materials, lighting, pattern recognition, clothing color, background illumination, headlight type and pedestrian movement. Just a few of the after dark data hazard data points we collect.
Driver speed choice and anticipation to non-immediate hazards such as curves, roadside obstacles, flashing lights, emergency vehicles all influence how a driver changes their speed or responses to each factor. How does crash risk increase when they do not modify their speed or change their response?
What is the likelihood of a driver being able to stop, slow down, steer or brake when trying to avoid an obstacle? What percentage of drivers succeed? Our data tells you the facts against each specific situation.
Approved and accepted for use in over 13 countries, our scientific approach and impartial collection of data is the antidote to bias. Our solution strives to include all relevant, scientific, and peer-reviewed data.

Regarding computer modelings of drivers’ response times, Dr. Paul Olson wrote: “The investigator who wishes to estimate response time for some situation not covered by one or more studies is forced to take his knowledge of the literature and extrapolate in an effort to estimate what it would be in the situation under consideration. Beyond question, having a general purpose model would be a very real advantage. Such an effort has been undertaken by Muttart (2003).”p.248
“Muttart’s work is important and represents a significant contribution in trying to deal with the real-world problems of driver PRT. The equations have been packaged and are being marketed [in IDRR], presumably to the persons involved in the investigation of traffic accidents. The work represents a significant and valuable addition to our understanding of the driver PRT.” p. 100-103.

IDRR is one of the best and most used tools in my recon kit, helping me answer a fundamental question of every case: was the collision avoidable? It gets better and more useful with every update and I look forward to seeing what’s next.

A lot of my cases involve recognition of path intrusion or closing speed and IDRR gives me an incredible foundation… when I testify about these issues. I can’t thank Jeff, Swaroop, Lynn, and Sunny enough for the work they continue to put into ensuring we’re all out there relying on good science.

Before IDRR, human factors research was out of reach. IDRR has become an invaluable tool in my toolbox of collision reconstruction software programs. A complete collision analysis and reconstruction simply cannot be completed without using this most valuable tool.

I purchased IDRR about 5 years ago at an IPTM Symposium and am extremely happy for doing so, The investment has been worth its weight in gold. I am able to validate the PRT calculations against studies to calculate the mean and standard deviations.

Prior to IDRR, I had to search through numerous references to provide a range of PRT pertinent to the case of interest. IDRR dramatically simplified that process for me. IDRR also provides data for the human factors specialist, beyond PRT.
Dr. John Lloyd, PHD Human Factors
I have found the program (I.DRR) to be very useful on a large number of cases. I appreciate that the formulas and references are explicitly stated or displayed, so that I.DRR results are easy to integrate into an expert report.
