Evaluation of the Impact of Reduced Conflict Intersections on Truck and Large Agricultural Vehicle Crashes tech transfer summary

چکیده
In general, RCIs (also referred to as J-turns or RCUTs) have generally been found to decrease crashes. A study by Inman and Haas (2012) compared crashes for nine intersections in Maryland before and after installation of RCIs. Before and after comparisons of traffic crashes were made for each main intersection of the RCI, the sections between the RCI, and the U-turn locations. An empirical Bayes analysis was conducted and a 62% decrease in crashes after the RCI treatments were installed was reported. Additionally, the authors concluded there was a 70% drop in fatal crashes and a 42% reduction in injury crashes between the 3-year periods of installing the RCIs.
