Econometric analysis of the impact of roundabouts on the number and severity of traffic accidents. Diploma thesis. Brno: Mendel University, 2015. This diploma thesis estimates the effect of converting conventional intersec-tions to roundabouts on the number and severity of traffic accidents. The effect is estimated in a Difference-in-Differences setup using data on 40 intersections con-verted to roundabouts and 40 conventional intersections that serve as a control group. The estimated effects, together with the existing estimates of the value of a statistical life, are then used as input data in a Cost-Benefit Analysis of converting intersections into roundabouts. The net present value of converting intersection to the roundabout estimated is estimated at minus 7 755 169 CZK, that is a net social loss. This is because in our data the number of serious injuries increased as a result of conversion. However, the results are not statistically significant, thus we cannot rule out the possibility that the conversion produces zero or moderate social benefits. The results suggest that more research is needed to ascertain whether intersection conversions are sound policy or a waste of resources
