Exploring the Influence of Tinted Windows and Other in-vehicle Distractions on Driver Detection of Pedestrians and Bicyclists

This project seeks to address increasing road fatalities in the United States, especially among pedestrians and bicyclists, by investigating how vehicle features such as tinted windows and in-vehicle screens impact driver visual perception and the safety of vulnerable road users. The scope centers on visibility-related safety issues near intersections and the potential added risks posed by heavily tinted windows, which may hinder both driver detection of pedestrians and cyclists and police or witness identification. The objectives are to experimentally evaluate the effect of varying window tint levels and screen use on driver attention, detection ability, and overall safety in low-light and low-contrast conditions. The method involves controlled studies using advanced eye-tracking technology to measure driver performance and behavior across multiple tint percentages, ultimately informing safer vehicle and roadway practices for non-motorized users that align with the Safe Systems Approach.
