摘要：	The primary objective of this research was to develop guidance for the design and application of shoulder and centerline rumble strips as an effective motor vehicle crash reduction measure, while minimizing adverse effects for motorcyclists, bicyclists, and nearby residents. The focus of the research was on (1) summarizing previous research and existing policies on the design and application of shoulder and centerline rumble strips, (2) quantifying the safety effectiveness of shoulder rumble strips on different roadway types, (3) providing guidance on the safety effectiveness of shoulder rumble strips placed in varying locations with respect to the edgeline, (4) quantifying the safety effectiveness of centerline rumble strips on different roadway types, (5) quantifying the safety effectiveness of centerline rumble strips along varying roadway geometry, and (6) developing statistical models for predicting noise levels within the passenger compartment of a vehicle for use in designing rumble strip patterns. There are several shoulder and centerline rumble strip design and application guidelines that can be developed based on converging findings from the existing literature and results from this research. Shoulder rumble strips may be considered for implementation on a range of roadway types, including urban and rural freeways, on- and off-ramps, multilane divided highways, multilane undivided highways, and two-lane roads. Criteria that may be considered for determining whether implementation is appropriate include shoulder width, lateral clearance, traffic volume, bicycles, pavement type, pavement depth, area type, speed limit, and crash experience. / Supplementary Notes: Prepared in cooperation with Pennsylvania Transportation Inst., University Park.
