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.
Traffic volume reductions on Clarke Road in north-eastern London, Ontario continue to demonstrate the effect that the Corona Virus has on the functioning of our society. This site has been monitored for the past 10 years and a number of articles have been posted on...
Gorski Consulting has collected data regarding the change in volume and composition of traffic on Highway 401 since the COVID-19 pandemic has taken effect. In the fall of 2018 Gorski Consulting conducted a number of 2-hour, videotaping sessions along Highway 401...
The superior design of expressways such as Highway 404 in Toronto should not result in a fatal impact to a bridge pillar. Yet, from the scant description provided by the OPP on their Twitter account this is what reportedly occurred. The collision likely occurred in...
Gorski Consulting has now completed the documentation of 560 instances of driver response to a red signal turning green at numerous intersections throughout London, Ontario. A dashcam was used in a vehicle that was positioned behind the drivers who were stopped at a...
Although the most severe, head-on collisions also provide the greatest opportunity to use the structure of vehicles in riding down the destructive forces of that impact. This was clearly shown in the OPP photo shown above, relating to a serious head-on that occurred...
It is hard to have traffic fatalities when there is no traffic. This may be what is in store in the short term as the Corona virus turns society on its head. A domino effect can be initiated when the Corona virus response causes large numbers of businesses and events...
If this were a horse race, all would be losers except Pandemic, the horse who came from behind quick, and from nowhere. Unfortunately this is not a horse race, a test drill, or a Hollywood script. It's the real thing. Hopefully, in a year or two we will look at these...
Some preliminary results are available from our documentation of driver's reactions to the change of a traffic signal from red to green. This data is for the year 2018 and includes 174 observations. The analysis involves examining the videotape of scenarios such as...
Do you respond to an impending collision in the same way as you respond to a traffic signal? That question is being examined through research by Gorski Consulting. In the past fews years vehicles stopped at traffic signals have been videotaped with a dash camera in...
Unusual things happen, but explanations would help. How does an unoccupied OPP SUV sustain major frontal damage with no injury to the occupants of the opposing vehicle? Firstly, the front ends of OPP SUVs are very stiff. Something like a Ford Explorer that may be...
Poor weather, large numbers of heavy trucks and a lack of safety education are a toxic mix on Ontario's expressways. This has been made apparent again when a winter storm passed through southern Ontario in the past couple of days. Police posted warnings before the...
Officially, the cause of a loss-of-control, median cross-over collision on Highway 403 near Brantford yesterday is claimed to be unknown. But certain facts point to failures and possible causes. Without official presence during the investigation it is difficult to...
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.
