Available in PDF, EPUB and Kindle. Book excerpt: Reduced visibility on the highway due to adverse weather conditions results in an inability of motorists to readily observe pavement markings, signs, and vehicles. The condition that presents the most serious restriction is fog, although rainfall during the night frequently creates serious visibility problems. Because of the ability of reflex reflective devices and materials to provide pavement and roadway delineation at relatively low costs, the feasibility of using them for roadway delineation and vehicle guidance during fog was investigated, with emphasis on the nighttime visibility characteristics. Also, consideration was given to various experimental methods of marker placement for roadway delineation and to protecting the markers from snowplow damage. Two types of corner-cube raised markers were placed along the highway edge line on 20-ft. (6.1 m) centers. In one placement concept, snowplowable and non-snowplowable markers were placed on the pavement surface; in a second, concept, the markers were recessed below the pavement surface in grooves. The marking systems were subjectively evaluated by observing the legibility properties during fog and noting the number of markers visible. Based on the observations, the raised pavement markers were thought to provide sufficient nighttime roadway delineation for vehicle guidance during light to medium density fogs. Although data were not available for dense fog, it is felt that adequate delineation would be provided for such fog conditions. The method of grooving the pavement in the vicinity of the edge line for the purpose of recessing the markers to provide snowplowability was found to be feasible, providing adequate drainage is provided and a groove is placed in front of the marker. The length of the groove depends upon the reflectivity-distance requirements.

This book was released on 2006-06-15 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Raised pavement markers (RPM) are used in highway centerlines and edge lines as a traffic safety measure to provide more positive guidance for motorists in inclement weather and low light conditions. They are applied by highway agencies as delineation treatments to improve driver preview distances. The Indiana Department of Transportation has installed RPMs on selected roadway sections primarily as position guidance devices in order to better guide drivers in night conditions. In Indiana, RPMs are installed on all interstate highways and multilane divided highways. However, RPMs are used on only a few of the Indiana's two-lane highways. It was found that two-lane rural roads in Indiana experience relatively large number of fatal crashes. Thus, INDOT engineers would like to know if the safety on rural roads can be improved by placing RPMs on more two-lane highways. They would like to find out how effective the installed RPMs are in improving the safety of the motoring public. If the RPMs are effective, what criteria should be applied to identify the roadway sections and curves for RPM installations to improve safety? To address these questions and concerns, this synthesis study was conducted to search answers from the published literature and to identify and summarize the effectiveness of RPMs and the criteria for RPM placement. The objectives of this study were (1) to locate and assemble documented information on RPM applications; (2) to learn what practice has been used in other states for RPM applications; (3) to organize, evaluate, and document the useful information that is acquired; and (4) to provide recommendations on RPM applications based on the evaluated information. Currently, there is not a uniform guideline among state highway agencies for RPM placements on different types of highways. Some states install RPMs non-selectively on all state-maintained highways. Other states select roadways for RPM installations solely on the basis of traffic volumes or on the basis of several parameters, including roadway type, traffic volume, safety record, and horizontal curves. Moreover, RPM replacement cycles vary from state to state. Through this study, the information on RPM effectiveness was located, assembled, reviewed, and documented.
