This report presents results from a survey of a diverse group of motorists perceptions and opinions of inlaid pavement markers. Respondents participated in one of three ways: They (a) experienced the markers first-hand by driving a designated route with researchers and then completed a questionnaire, (b) were approached at a highway rest stop outside of St. Louis and asked to complete a questionnaire, or (c) were solicited via e-mail and asked to complete an online questionnaire. Results indicate that motorists overwhelmingly reported favorable perceptions and opinions of inlaid pavement markers. They reported that the markers enhance visibility of lane delineations, particularly while driving in rain and fog, thus making them feel safer while driving. Roughly two thirds of all respondents reported that it would be “extremely useful” to have inlaid pavement markers on all roadways, with another 15% of respondents reporting that such omnipresence would be “very useful.” No differences in responding were observed between age, gender, or occupation groups.
