In response to Value Engineering Proposal #M-26, a study of the feasibility of adopting a 10 ft. mark--30 ft. gap centreline pattern for use on 2- and 4-lane rural roads was conducted. The study included a literature review, field studies of traffic speed and lateral placement on rural highways, a motorist opinion survey, an estimation of expected monetary savings, and a discussion of operational problems and implementation strategies. In terms of traffic performance and public reaction, it was found that no significant differences exist between the 10:30 pattern and the currently used 15:25 pattern, and that annual savings of from $50,500 to $89,500 are possible if the 10:30 pattern is used. It was recommended that the Department of Highways and Transportation adopt the 10:30 centreline marking pattern on all rural highways. (Author)
