Knott Laboratory provides forensic engineering and animation, Civil & Structural, and Fire & Explosion Investigation services to reconstruct accidents.


Pedestrian Accidents

These accidents occur because the driver is either inattentive or the pedestrian is difficult to see.


Accidents involving vehicle and pedestrian are analyzed by Knott Laboratory. Typically these accidents occur because the vehicle driver is either inattentive, or the pedestrian is difficult to see, either due to clothing that the pedestrian is wearing, lighting available at the accident scene, or a combination thereof. Driver elements, such as perception reaction times (PRT) and expectancy of pedestrian location are also considered during accident reconstructions.

Night-time and day-time visibility studies carried out by Knott Laboratory help to determine accurate driver visibility of pedestrians at accident scenes. Night-time visibility studies consist of analysis of overhead lighting from street lights, as well as vehicle headlight illumination.
