SPR-4739: Sinusoidal Rumble Strips Measures of Effectiveness

This project will estimate and compare the safety performance of conventional and sinusoidal rumble strips to inform INDOT’s decision of rumble strip design. Edge-line rumble stripes narrower than standard 12” will be checked for safety and warning effectiveness to accommodate pedestrians and bicyclists within existing road shoulders together with stripes. Crash Modification Factors will be estimated for several types of crashes at three levels of crash severity to help select alternative safety countermeasures including rumble stripes lateral location: centerline only, shoulder only, and centerline plus shoulder.
