In response to Value Engineering Proposal #M-26, a study of the feasibility of adopting a 10 ft. mark 30 ft. gap centerline 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 centerline marking pattern on all rural highways.
The effect of 8-in. wide edgelines on the incidence of run-off-the road (ROR) and related accidents was evaluated. The treatment locations consisted o...
This interim report presents the results of an evaluation of 4-in and 8-in wide edgellnes on the lateral placement and speeds of vehicles on two-lane ...
