Accident Investigation & Crash Reconstruction
Forensic Mapping and Data Acquisition
The preservation of scene evidence is critical to an investigation. Crane’s experts specialize in complete, on-site forensic mapping services using the Total Station system.
Forensic mapping allows our team of experts to recreate accident scenes by measuring location, shape and size. The evidence along with other objects is documented and recorded. An accident scene can involve road width, shoulders, intersecting roads, sidewalks, and trees and other objects. The collection of such evidence is an invaluable tool for the reconstruction of the accident.
Crash Data Retrieval
Crash Data Retrieval (CDR) relies upon an instrument installed in most passenger cars, SUVs, and trucks called an event data recorder (EDR); they are sometimes referred to as the "black box".
An EDR is generally part of a vehicle's airbag control module, and can be configured to store recorded information such as speed, brake use, or restraint system performance when a vehicle is involved in a crash event. EDRs are triggered by sudden changes in speed (also called Delta-V), and can help determine what the vehicles were doing before, during and after a crash event.
The Crash Data Retrieval System is the essential tool for
- Obtaining pre-crash and crash data from vehicles
- Obtaining crash severity data (deltaV)
- Giving a more accurate and detailed assessment of speed analysis/crash severity
- Providing more accurate data in your collision reconstruction
- Making determinations if certain crash scenarios are possible
- Being prepared to explain the crash data if the "other side" also has the crash data
- Make rapid decisions on potentially fraudulent claims
- Quickly make accurate, defensible determinations where liability is questioned
Photo Modeler and Animations
Photo Modeler photogrammetry software provides accurate measurement and 3D models for many accident reconstruction and forensic tasks.
Post forensic mapping and CDR acquisition, the data is downloaded using Bosch equipment and analyzed as part of the investigation. The forensic map can then be used to recreate 2D or 3D images and animations for the reconstruction of the accident.
Our technical team provides the images, models and animations required for to support the facts in the case.
