In addition to our vast experience, specialized training and education, the staff at Introtech uses the latest technology to measure and analyze the physical evidence from the crash scene, the vehicles and the overall environment.
Many modern vehicles may contain additional vital evidence from on-board navigation systems, air bag control modules, engine control modules, power train control modules, advanced braking systems and other systems The Introtech staff has the training, hardware and software to collect and properly analyze this data.
Our staff is trained and experienced in the technical aspects of the analysis of environmental issues, traffic control devices, navigation systems, human factors, biomechanics and other specialized issues that directly relate to transportation casualties. We apply this technical knowledge to the land, marine and aviation environments.
We employ sophisticated computer programs as well as computer simulations to assist us in our analysis and calculations of crash events. We have the in-house capability of preparing 2-D/3-D animations and other exhibits such as CAD drawings and power point presentations to graphically demonstrate our opinions to the trier of fact.
3D Crash Site Scanners
the scanner from any object in the direct line of sight of the laser beam. Within minutes the scanner produces highly detailed three-dimensional images of even the most complex scenes or objects. The laser can be moved to multiple locations around an object or scene and then in the software program, all of the various images are stitched together for a complete 3-D view of the object. The resulting images are a compilation of millions of 3D measurement points that generate a precise documentation of the scanned object.
When it is necessary to measure vehicle acceleration performance we utilize the VC3000DAQ to determine speed, acceleration (both lateral and longitudinal), time, distance and g forces. The data can be displayed in tabulated or graphical formats. We have used this instrument to measure vehicle performance for a wide variety of vehicles including construction equipment, commercial vehicles, motorcycles, warehouse equipment, boats and passenger vehicles. The external sensors of the VC3000DAQ can also be installed to measure acceleration of objects inside of a vehicle such as the occupants, wheelchairs, cargo, etc.
Many of the standard coefficient of friction charts are outdated and must be applied to a particular case with prudence. At times the most effecive way to determine the coefficient of friction of a road surface is to conduct a set of test skids. We use the Vericom VC2000 perforance computer or the VC3000DAQ, depending on the unique aspects of a case. To supplement friction testing, we also have a variety of drag sleds for motorcycle tire friction evaluation.
Not every case requires a set of test skids. To assist in determining the probable friction of a road surface we have compiled a statistical analysis of the hundreds of test skids we have conducted throughout the United States.

Forensic mapping is the process of mapping scene evidence to produce accurate scale diagrams. A working scale diagram is often crucial in the reconstruction of a transportation crash. Time, speed, distance and human factor analyses require the examination of evidence in its precise dimension and proper spatial relationship. Introtech uses ES Series Topcon and Sokkia theodolites to map scenes and other evidence.
With the measuring data collected along with scene photos and video, Introtech’s graphics department utilizes the latest computer aided design (CAD) software to produce high quality demonstrative exhibits. Our in-house graphics department utilizes foam board exhibits, PowerPoint presentations, 3D animations and simulations to enhance the jury’s comprehension of our opinion and its foundation. Many of our clients have successfully used our exhibits in mediations and arbitrations.
Introtech has purchased the most current versions of both the FARO Reality and FARO Zone 3D softwares. These programs are the latest and most innovative 3D animation and simulation product on the market today. Animations are being used with greater frequency in courtrooms as impressive visual aids that visually demonstrate the results of our reconstruction.
