A view at one of the more recently built roundabouts in the city of 's-Hertogenbosch in the South of the Netherlands. This roundabout came in the place of an ordinary four arm junction with traffic lights. When the city announced that the junction would be changed into a roundabout people had a hard time believing this would be possible at all. They thought there would not be enough space. But it proved to be very possible indeed. Traffic now flows very smoothly.
Interestingly enough Google Maps shows the before situation, but once you start StreetView it shows the current situation.
|Before: a junction with traffic lights and separate cycle paths.|
|After: roundabout with separate cycle paths, the lights were removed. Note that this roundabout design is responsible for dozens of injuries per year in the Netherlands.|
Update: It seems people are taking this design presented by a guest blogger as something to aim for. Please note that this is not the safest design of roundabout which is possible and we do not suggest copying the design shown in this blog post. The particular example shown here closely resembles a roundabout in Groningen to which we take people on study tours in order to see how NOT to design a roundabout. This relies too much on drivers being perfectly behaved. and on cyclists having eyes on the back of their heads.
Other posts on this blog show safer roundabout designs where cyclists either don't interact at all with cars on the roundabout or where they give way on those arms where there are interactions. These other roundabouts provide a better example for other nations to follow.
