Data Analysis
The horizon of accident reconstruction is undergoing a transformative shift towards data analysis. In the contemporary landscape, data is perpetually captured and stored across a diverse range of devices. Closing doors to this supplementary information methodology would be a misguided approach.
Quite the opposite, it’s becoming evident that the role of an accident analyst will increasingly shift from classical mechanics to in-depth data analysis. In an era where every mobile phone, car, and sports watch persistently records movement patterns, this reservoir of information contains crucial insights for deciphering accidents.
AnalyzerPro stands poised with an array of interfaces supporting commonly used data formats, including GPS and data from prevalent measuring devices.
As video recordings become ubiquitous, harnessing this source for accident analysis gains paramount importance. AnalyzerPro strides forward with an innovative tool, automatically identifying moving objects in videos and determining their velocities. This capability seamlessly integrates data from static surveillance cameras into accident analysis calculations.
Addressing wide-angle lens distortions, a video rectification method heightens accuracy. Visualized in diagrams, the red line depicts the data, while the blue line interpolates it into rounded driving behavior.
Vehicles continuously collect driving data, with Bosch’s “Crash Data Retrieval” (CDR) tool emerging as a market leader in accessing this information. In accidents, Bosch’s CDR accesses the Event Data Recorder (EDR), populated by vehicle sensors, including airbag sensors. This repository captures pre-collision driving behavior and collision-related deceleration over five seconds. AnalyzerPro extracts pre-collision behavior from up to six trigger events, empowering experts with immediate insights.
Critical to data analysis, digital tachographs store data in DDD files, meticulously recording speeds at 1 or 4 hertz. This precision facilitates correlations between time and real-time driving behavior, enabling accurate estimations of pre-collision speeds. AnalyzerPro seamlessly processes these data, including the latest-generation recording devices.
Emerging from trends in sports and cycling, this dimension infiltrates accident analysis. Formats like FIT or GPX, employed by many sports watch manufacturers, are noteworthy for recording data. Despite their varying resolutions, these datasets offer multiple comparative values for drawing meaningful conclusions.”
