Halation or irradiation makes guide sign fonts difficult to read. Missing the necessary guide sign information causes anxiety and confusion to drivers, and hence may lead to crashes. In order to avoid or mitigate the situation a newer font, Clearview, is used to provide better readability at long distances. In a similar context the lack of brightness in sheeting material for warning signs reduces conspicuity of sings. Installation of fluorescent yellow sheeting has been done to provide signs with more noticeable and brighter materials. This observational before and after study is an evaluation of the safety and economic benefits of the Clearview fonts and fluorescent yellow sheeting installed in Michigan freeways and non-freeways. Safety Performance Functions (SPFs) and Crash Modification Factors (CMFs) for Clearview fonts and fluorescent yellow sheeting were developed. A perception survey was conducted to identify driver’s preferences on the Clearview fonts and fluorescent yellow sheeting.
