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.
Results from several observational studies by Gorski Consulting show that there are far fewer females riding bicycles than males in London, Ontario. The results of three different studies are consistent with this conclusion. The studies involved the following:...
No one knows what kind of injuries are occurring in cyclist, e-bike, skateboard and e-scooter crashes in Ontario. In fact, little data is available about the general characteristics of riders and their speeds. A recent article from an injury study in Brisbane,...
It is rare when we can compliment Ontario police forces in being transparent and useful toward educating the public on road safety. The OPP in Ontario have been an exception, at least with respect to providing photos of serious collisions in their jurisdictions. Most...
When a clearly unexplainable happening is visible in an OPP photo, and the OPP do not provide an explanation, the public also has no idea of its relevance - and that is a genuine problem. Medians contain a variety of barriers and energy attenuation devices to control...
A new playground has been completed next to the Thames Valley Parkway (TVP) south of Trafalgar Street in London, Ontario. Concerns about a northbound downgrade on the path were previously expressed as high cyclist speeds were occurring on the approach to an...
You can complain about the quality of the roads you drive but Gorski Consulting is the only site that provides, objective, comparative data for many roads in Southern Ontario. New data has now been uploaded to the "Road Data" page of this Gorski Consulting website,...
Don't speculate about someone's death until you know. But when will you know? Likely never. And that is also not helpful. As a result of a July 3, 2021 collision, a westbound driver was killed when his car apparently drove into the rear of tractor-trailer on Highway...
Stiffer stunt driving penalties have been introduced in Ontario effective July 2, 2021. But how many stunt drivers will be caught is an important question. Is it like winning a bad lottery? A CTV News article reported yesterday that: "Between January 2021 to the end...
In Toronto, Ontario recent news reports indicate that approximately 20 to 30,000 tickets are issued per month from the operation of speed cameras which began operation in July of 2020. Politicians in other cities like London, Ontario have been waiting for the Province...
Whenever a vehicle passes through the median of a high-speed expressway and fatalities occur, questions are asked because median barriers exist that are supposed to prevent such tragedies. But it is revealing how often official agencies skirt around the discussion....
Downslopes on cycling paths create high cyclist speeds and these result in safety problems. While this would appear to be simple to recognize, some municipalities and courts in Ontario find this relationship difficult to accept. Previous testing by Gorski Consulting...
When fatal results occur in relatively minor collisions further answers are warranted. The above photo was provided by the OPP on their Twitter account in identifying that this collision resulted in a fatality, presumably in the dark SUV that is seen against the...
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.
