Crash Data Recorders
Trials and Testimony
Site and Vehicle Examinations
If possible, call us immediately after an accident occurs so we can attend the crash site and document evidence before it is altered and destroyed. We can also provide examinations after vehicles are moved to a holding compound.
During examinations, we use still and video cameras to document evidence and measure the site to create a scale diagram. Any evidence found is secured for analysis. At the holding compound, vehicles are photographed and the location of collision evidence is measured along with the profile and magnitude of crush. The status and functioning of safety devices are documented – the Crash Data Retrieval toolkit is used to download crash data from air bag control
If required, we re-attend the collision site or vehicle for additional observations and analysis. At a collision site we may set up a roadway grid to document the speed, position, and specific behaviours of drivers – captured by video camera mounted to a 20-foot pole. The output displayed from a radar gun is videotaped to assess the likely speed of typical vehicles, which is used as a reference toward estimating the actions of an accident-involved driver.
We re-create night time accident scenarios using similar vehicles and lighting conditions. Police assistance may be used to close a road segment or natural reactions are obtained without a driver’s awareness of the testing.
The National Automotive Sampling System (NASS), a division of the U.S. National Highway Traffic Safety Administration (NHTSA), is an invaluable database to those in the insurance and legal industries.
The Crashworthiness Data System (CDS) of NASS keeps data on thousands of crashes. Research teams at Primary Sampling Units across the country study 5,000 crashes annually. Skid marks, fluid spills, broken glass, and bent guardrails are studied at crash sites. Vehicles are then located to be photographed, measured, and to identify the interior locations struck by occupants. Researchers then interview crash victims and review medical records to determine the nature and severity of injuries.
There are more than 140,000 crash files in the NASS CDS. Although they are designed for analysis with a specialized statistical analysis package, analysis can also be conducted simply by going to the Web site and selecting a list of cases meeting specified criteria.
The safe transportation of children on school buses is paramount. An important factor in that safety is the reaction of school buses to road surface defects. Are school buses prone to loss-of-control because of their inferior characteristics compared to other...
Little is publicly known about the effects that a rough road surface can have on the motion of a motor vehicle. Gorski Consulting has recently conducted testing with school buses to supplement the growing results of testing already posted to this website on this...
The condition of road surfaces can be easily identified using the accelerometer and gyro sensors of a smartphone. This has been demonstrated in testing performed by Gorski Consulting using an iPhone and multiple video cameras attached to a 2007 Buick Allure passenger...
Gorski Consulting has completed a review of 8 years of photos of cyclists riding on or adjacent to roads in London, Ontario. The years 2013 to 2020 showed the characteristics of the riders, their actions and the safety of the roads on which they travelled. For...
Undoubtedly, adjusting your skates in full flight will deliver you to church in an unexpected way. This gentleman must have believed he was invincible as he skated along a street in London Ontario without paying attention to traffic.
At Gorski Consulting we have stepped up our efforts to provide data about cycling in London and South-Western Ontario. As governments in North America are rapidly changing their roadway networks to create more access to active transportation, it is believed that the...
A Highway Traffic Act cannot solve all of our road safety problems. We need detailed collision information in order to recognize the relative risk of unorthodox human behaviours on our road systems. As shown in the above photo, an elderly male rider has...
If you observed this view for 1 or 2 seconds would you correctly identify the object in the road? Hindsight causes many to judge the actions of a driver based on what they know after a collision has occurred.
Many persons who are deserving of charges are not captured by typical investigations of motor vehicle collisions. Look at the scenario above which commences when traffic is diverted due to a closed lane. The driver of the BMW SUV has been forced into the left lane...
Why is it irrational to see a pedestrian walking within a travel lane with their back to traffic? Let us consider the photo below which shows a pedestrian walking on a cycling lane. Is this dangerous? Not only is his back to traffic but the next photo shows that he is...
As regrettable as they are, collisions involving celebrities are a time when a large segment of society is interested in knowing what happened. And this can be a valuable opportunity to educate those who may otherwise be unreachable. But those opportunities are almost...
Sometimes evidence that may be uncommon can break open a case if an investigator/analyst understands that evidence. That was the message given to members of the American Academy of Forensic Science (AAFS) in a presentation given by Zygmunt Gorski at its annual meeting...
Zygmunt Gorski has been involved in the analysis of motor vehicle accidents since 1980. Initially employed as an accident investigator with the University of Western Ontario Multi-Disciplinary Accident Research Team (1980-90), Gorski then worked as an Accident Reconstruction Consultant with a forensic engineering firm in Kitchener and Toronto (1990-95), before opening his own consulting business in 1995 which he continues to operate to this day. Although Gorski’s interest has always focused on the physical evidence resulting from motor vehicle collisions, he has been involved in a variety of analyses ranging from injury assessments in his earlier times to the use of multiple video cameras and roadway safety issues in more recent years.
