Impact of Centerline Rumble Strips and Shoulder Rumble Strips on all Roadway Departure Crashes in Louisiana Two-Lane Highways

The goal of this project is to evaluate the safety impact of centerline rumble strips (CLRS) and shoulder rumble strips (SRS) on two-lane highways under the Louisiana Department of Transportation and Development (LADOTD) system. Specifically, the objectives are to investigate safety effectiveness of CLRS and SRS (in single or combination) on two-lane highways under the LADOTD system, and estimate the benefit-cost ratio of the countermeasures.
