Collision Reconstruction Add-In FAQ
0 mins to read•
Browse frequently asked questions about the Collision Reconstruction App, including what constitutes an accident, how the point of impact is determined, what happens in an instance of multiple collisions, and how to report a bug.
When a vehicle collision occurs, the accelerometer within the Geotab GO telematics device will detect an accident-level event and record second-by-second data of the accident at 100 Hz frequency.
Point of impact is calculated based on the accelerometer data at the moment of impact. The collision point is based on acceleration magnitude and angle and may vary if installation of the device is moved outside of the driver side of the vehicle. The impact location is also rounded to the nearest degree of freedom.
In some cases accidents may not be automatically detected by the add-in. These can include minor collisions, device losing power, device not securely installed etc. If the add-in is unable to detect an accident please contact Geotab support for manual extraction.
Geotab devices use an acceleration threshold of 2.5 G (24.5 m/s^2) as an accident event.
Currently the add-in only analyzes the latest accident. Multi-impact collusion support will be added in with future updates. To analyze multiple impacts/collisions, narrow down the selected time period.
As the add-in is in beta we are constantly working on fixing any bugs or inconsistencies. Please contact Geotab support for any questions or issues.
The report is for illustrative purposes only. The report has been assembled automatically using data reported by a GO device by software in BETA release. There are many ways in which automatically generated reports can be in error. Some directly measured quantities in the report, such as acceleration, speed, and GPS location, are subject to their usual uncertainties and measurement errors. Derived quantities, such as point of impact, are also subject to potential calculation errors. The vehicle image displayed in the document is a generic image of the vehicle type, it does not serve to portray an accurate image of the exact vehicle or any additions/modifications done to the vehicle such as trailers, this image can also be edited by the user generating the report. The software is still in development and performance characteristics remain uncertain. Accordingly, the report may serve as a starting point for your investigation of an incident, but no conclusions should be drawn from it without a trained, Geotab expert to interpret it.
