FIAT Traffic Accident Reconstruction Team -Frequently Asked Questions

Frequently Asked Questions

1. What tools do the Reconstructionist use?

New technology has become available to make the FIAT Crash Reconstruction Specialist's job easier, faster, more accurate, and safer. New technologies implemented include the use of the Total Station and the use of computers for analysis.
The total station is a combination of an Electronic Distance Measuring Instrument (EDMI) and a theodolite. The total station can be set up on or off of the roadway.

Q - How do Reconstructionist collect evidence and measurements?

Evidence is located by an investigator holding a pole with a prism over a location of evidence. The instrument is focused on the prism and the operator takes a 'shot' by pressing a button on the data collector. An infrared beam is emitted at the prism and is reflected back to the instrument. The operator then enters a code for the specific 'shot' and the investigator with the pole moves to another evidence location, and the process continues. The data collector records the distance, angle and elevation for each 'shot'.
Crash scenes can be measured using the total station and, when completed, the data can be downloaded to a computer. This allows the FIAT Reconstruction Specialist to review the data collected, ensuring that all necessary data is collected and documented before leaving the scene. Once back at the officer’s respective department, the data can be downloaded into other software programs for completion of calculations and diagrams.
