Scene Evidence can be collected through laser scanners and site surveys. These 2-D and 3-D models provide accurate representations of the accident scene. This technology further allows us to capture 3-D renderings of crushed vehicles for analysis and calculations.

Crash Data Recorder Download & Analysis


Crash Data Recorders provide pre-crash data to include speed, braking, steering angle, and much more. In addition, crash data such as delta-v and principle direction of force are collected and can be harvested.
