Safety is of paramount importance in traffic engineering. There are many factors that can affect a vehicle’s ability to stop safely, which is a main reason for accidents. The driver’s reaction time, the speed of vehicle, the grade of the road and the friction of the road are all aspects that the expert witness must look at.  The greatest consideration of traffic engineers is safety, but traffic engineers also consider the importance of traffic facilities that function economically, efficiently, and rapidly for effective and safe movement of people and goods.

Engineering Expert Witness

An expert engineering witness is most highly requested by lawyers and police requesting a reconstruction of an auto accident. Road vehicle accidents are complex to analyze and involve at least three separate influences: the human element, the vehicle element, and the highway element.  To determine the most likely cause of an accident is the engineering expert witness’s main responsibility. 90% of automobile accidents are caused by operator or operational factors. Varied information is gathered to analyze the elements of  an accident such as; road conditions, statements, photos, physics of the situation and skid marks.

Our experts may use crash testing, exemplar vehicles, computer graphics/animation reconstruction, along with Newtonian principles and related science to determine what really happened.
