HEADLAMP PERFORMANCE FACTORS AFFECTING THE VISIBILITY OF OLDER DRIVERS IN NIGHT DRIVING

The first section of this paper presents the current state of the art of motor vehicle headlighting, covering the following topics: U.S. and European designs; aim and alignment; dirt, rain and fog as causes of reduced light; interaction with street lighting; future trends; glare disability; glare discomfort; glare from rearview mirrors; mounting height of headlamps; headlamp aim; headlamp washing and wiping; and factors other than those related to the design of the vehicle (e.g., reflective materials for traffic signs). In section two, changes to improve night-driving visibility are discussed. Areas where such changes appear to be warranted and feasible include aim and alignment of headlamps, the mounting height of headlamps, the reflectivity of rearview mirrors, the cleanliness of headlamps, and refinements to the meeting beam. Also discussed are environmental variables (their reflectivity) and how they affect visibility. The third and final section draws attention to research needs.
