Title:

Examining Driver Preference for Regulatory Headlight Use Signs Design in Different Weather Conditions: A Driving Simulator Study

Abstract:

Headlight use signs are regulatory traffic control devices that require road users to turn on their vehicles’ headlights manually during the daytime. It is mainly used when a certain roadway section encounters an increase in crashes related to vehicles' conspicuity. According to a field study conducted in Wyoming, headlight use signs have low compliance rates. This low compliance might be due to the sign design itself. In addition to the basic headlight sign design, two upgraded designs were proposed and tested in different weather conditions in a driving simulator environment. Survey responses were collected to obtain public preference for the upgraded designs. Factor Analysis (FA) and analysis of variance (ANOVA) were adopted to validate and analyze the collected responses of the surveys. Vehicle dynamics of the simulator were analyzed to examine the difference in driving performance at headlight sections. Most of the participants reported that the basic headlight use sign (the original design) is considered as a poor design and the third modified design is a better design. ANOVA results showed that there was no significant difference between the two newly proposed designs. Vehicle velocity was used as a surrogate measure in the performance analysis. The results showed that comprehending information from the third headlight use sign design was significantly easier, as no reduction in speed was encountered. This study would provide insights for transportation agencies, in Wyoming, to enhance highway safety and help in decreasing crashes related to visibility and noticeability of the headlight use sign.
