Abstract
It is generally considered that modern roundabouts reduce vehicle crashes, because traffic speeds in roundabouts are lower than in other signalized intersections. It is also considered that there are less conflict points in roundabouts. On the other hand, modern roundabouts are less expensive than the traffic signals. These obvious advantages led many local authorities to the conslusion that it is a good option to convert the existing signalized intersections into roundabouts. Having the opportunity to record driving data before and after converting some signalized intersection to roundabout, our team made an analysis of the differences in driving parameters before and after.
