Human factors and dynamic roadways and in-vehicle lighting conditions

Abstract

A field investigation of the dynamic roadways and in-vehicle lighting conditions was performed. The variation in ambient lighting levels for drivers in-vehicle while driving was measured. Typical values and variability of lighting levels over time for nine sites in Ann Arbor, Michigan (e.g. rural, suburban, city streets, expressways, etc.) on a cluster near the radio within a 1986 Honda Civic, and the driver's view locations were determined. A sampling rate of 3 to 10 Hz was established for automatically adjusting the control panel lighting level for dynamic lighting conditions during the day and at night. The data obtained from this study are intended to provide photometric information to engineers to design the interior display panels within vehicles equipped with the Intelligent Vehicle Highway System.<>
