VCG Human Factors
Human Factors is the science of human interaction or reaction with mechanical devices or processes. The CED Vehicle Crash Group (VCG) has forensic engineering expertise relating to human interaction with vehicular accidents. This experience is divided into the following two parts:
Perception and Reaction Time (PRT)
Our engineers use state-of-the-art software that measures the ability to perceive a hazard and then react to that hazard. Drive 3 is a vehicular software program development created by a Ph.D. Psychologist with a vehicular accident reconstruction education. This program compiles a vast majority of perception studies that have been performed and calculated based upon parameters of what a normal reaction time should be considered. By utilizing Drive 3 and other advanced computerized programs, our engineers can calculate the reaction time based upon four factors:
These factors and their input allow our engineers to determine perception reaction times that are based on scientific research.
Visibility most often deals with line of sight of a reported hazard that contributed to an accident. These studies can be divided into three parts; lighting, stationary objects and moving objects. The aspect of lighting most often deals with the amount ,whether there is too much or not enough lighting. Roadway designs can have instances where sunlight is too bright without warning or nighttime where lack of light can be a potential causation to an accident. CED engineers utilize meters and other equipment that can measure the light at accident sights using weather mapping, sun positioning and light produced from such things as headlights and street lights.
