Safety Evaluation of Czech Roundabouts

Popis výsledku v původním jazyce

Roundabouts around the world are often seen as a beneficial measure for intersection safety. While also in the Czech Republic their numbers have grown in recent decade, their safety impact has not been fully studied still. At the same time Czech roundabouts have been sometimes seen as unpopular, including doubts about their benefits. This situation inspired the authors to investigate three general hypotheses related to Czech roundabouts: (1) Roundabouts are safer than traditional intersections, (2) Roundabout conversions are beneficial for safety, and (3) Czech roundabout safety performance is comparable to other countries. The paper provides the information and analyses in order to test these hypotheses. The final results are mixed: compared to traditional intersections safety at roundabouts has been gradually improving in recent years and before-after study of urban roundabout conversions yielded positive crash modification factors; on the other hand Czech roundabout expected crash f
