Wolf's visibility experts have extensive experience with issues related to lighting, optics, conspicuity, line of sight and human factors. Our senses link us to the outside world. Vision is the richest of the human senses. We are highly dependent on seeing to perform many activities such as operating motor vehicles, walking, reading, etc. Light is the basic stimulus for vision. Understanding how light behaves in the environment is the first key to understanding visibility.
In addition, we must understand the optics, the basic physiology of the human eye and how these visual systems process the light stimuli to produce the final perception.
Many accidents result from failure to see/notice features within a scene. Lighting levels, scene contrast and changing scene elements may all be relevant to these failures as well as weather conditions, viewer visual capabilities and viewer attention/distraction.
Mirrors, sight obstructions and other vehicle configuration elements may reveal that the driver’s view was limited at a critical time. Often, the vehicles involved may be surveyed to assist in later development of graphic portrayals and other demonstrative evidence.
