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.

It is the most indispensable software in my toolkit.

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.
