DAYTIME RUNNING LIGHTS PROJECT I: RESEARCH PROGRAM AND PRELIMINARY RESULTS

The program consists of various studies designed to determine the effects of daytime driving lights on driver behavior and crash involvement. Experimental studies are being used to investigate the effects of driving lights and various levels of ambient illumination on the ability of drivers to detect vehicles and to estimate their relative position and velocity. Results of pilot experiments using both field and laboratory procedures indicate that drivers are able to detect oncoming vehicles at further distances when the vehicles have their headlights on, regardless of the level of ambient illumination employed. Controlled observational techniques are being used to determine the effects of the use of daytime driving lights on crash involvement. Details of the study are presented along with descriptions of supporting research that is being performed. /Author/
