A System Approach to Safe Winter Driving Considerations: The Visual System 920020

A systems approach is used to analyze the problem of providing optimum visual capabilities to deal with the demands required for safe driving in cold weather. Using a systems analysis approach, the problem is divided into its constituent parts (e.g. road conditions, vehicle features and design, the human components, etc.) and then these components, as they pertained to the defined visual system, are addressed.. Under temperate driving conditions, visual acuity and field of view are two of the most important considerations for safe driving. While these still remain important during winter driving conditions, windshield clarity and the problems associated with it, becomes extremely important. These three requirements have many related characteristics that may be overlooked when a systems approach is not used.
