Investigating Safety Impact of Centerline Rumble Strip, Lane Conversion, Roundabout and J-Turn Features on Louisiana Highways

The goal of this study is to evaluate a few relatively new crash countermeasures on Louisiana highways including the centerline rumble strip, lane conversion (four to three and additional analysis on four to five-lane), and the restrictive median opening on high speed corridors. Specifically, the objectives are to conduct before-and-after study and exploratory data analysis for centerline rumble-strips, the lane conversion, roundabout and the J-turn treatment (restricted median opening on highways in Louisiana and perform cost-benefit analysis for all investigated safety features.
