Traffic Collision Consultants Incorporated consists of an ACTAR certified traffic collision consultant who is a distinguished retired member of the San Francisco Police Department. He previously held rank in both supervisory and investigative positions.

In order to conduct the various types of analyses, TCC Inc. utilizes different traffic collision tools ranging from computer programs to crush deformation jigs to highly sophisticated vehicle crash system read-outs. Below are some of the tools used:

Computer Programs
Our experts utilize computer systems ranging from vehicle specification programs (such as Expert Autostats) to complete reconstruction systems (such as AR PRO and SLAM), which aid in producing results that can be produced/enhanced for visual aids.

DBD Crush Deformation Jig
Pictured above is the crush deformation jig in use. It is a tool used to measure the inward deformation of a motor vehicle for speed and force direction analysis.

Bosch Crash Data Retrieval System
TCC Inc. has the capability to download vehicle-specific crash information data that could be used to analyze and reconstruct collisions just like airplane crash investigators do when they retrieve the data from "black boxes." Our experts are specifically trained and certified in the Bosch Crash Data Retrieval (CDR) system. This retrieval system allows the expert to download pre-crash and post-crash data from the on-board diagnostic system already in place. Currently, the software and interface supports passenger vehicles, Light Trucks and SUV's manufactured by General Motors, Ford and Chrysler. This technology can be used to analyze the impact speed of a supported vehicles airbag control module from 5 seconds before the impact right up to impact. The information gained may consists of vehicle speed, braking status, delta-V and time analysis.

Traffic Collision Consultants Incorporated is here at your disposal to handle all your forensic traffic collision needs. Our San Francisco based firm consists of fully trained and court certified ACTAR accredited reconstructionists who specialize in reconstructing motor vehicle collisions for civil and/or criminal litigation. We also utilize the highly technical Bosch Crash Data Retrieval System, which allows the expert to download crash and pre-crash data from the vehicle's on-board diagnostic system (OBD).
