SPR-4852: Safety Performance of Centerline Paved Pavement Markers
The study will estimate the safety effect of raised pavement markers (RPMs) installed on Indiana rural two-lane roads with various road horizonal alignments. The results will include Indiana Crash Modification Factors/Functions (CMFs) to support effective use of RPMs in conjunction with other safety improvement solutions. The CMFs at three levels of crash severity outcome will be implemented in the Indiana safety management and its decision making. The project is also aimed to evaluate the safety effectiveness of the centerline RPMs applied in combination with rumble stripes to identify the conditions where this joint treatment is advantageous. Specific recommendations will be provided for specific traffic conditions, speed, and roadway characteristics.
