      abstract = {This research addressed two questions: “Are roundabouts on  rural high-speed roadways safer than
two-way stop  controlled (TWSC) intersections?” and “What economic  benefits can be expected
from converting TWSC intersections  to roundabouts in terms of safety improvement?” Crash
and  traffic data on four TWSC intersections that were converted  to roundabouts in Kansas were
analyzed using the empirical  Bayes before-after evaluation method and crash costs were  applied
to evaluate economic benefits. Analysis showed that  fatal, non-fatal, and property-damage-only
crashes were  reduced by 100%, 76.47%, and 35.49%, respectively. The  annual monetary value from
this reduction was between  $1.0—$1.6 million in 2014 dollars.},
