Full-scale studies are most often carried out in order to understand the subtleties of a scene. Environmental, lighting, vehicle, and object conditions must also be considered in detail in conjunction with the approach paths and speeds to understand the situation being confronted by a motorist.
Once all matters associated with the driver's approach are understood, the human factor issues of perception and reaction are accounted for, and the ability for the vehicle to be slowed or steered are determined, we can often render hypothetical opinions on collision avoidance potential.
The opportunity for a driver to avoid a collision with another object is one of the most common analyses we are asked to carry out. To provide an opinion in this regard, one must first understand the point at which the object of concern becomes detectable and then discernible.
