Safe roundabouts revisited: There’s increasing evidence that this design is the safest for cyclists
|The safe roundabout design for cyclists looks like this. Please
read video as both of those describe the features of this design
There’s been quite a lot of news recently about roundabouts in the Netherlands and I’m pleased to say that the new statistics are highly supportive of my previous article about how a truly safe roundabout should be designed for cyclists. Here in Assen we use a design which is different from much of the rest of the country and as a result far fewer cyclists are injured on our roundabouts. Injuries occur elsewhere, but I don’t know of any which have occurred on these particularly safely designed roundabouts. Please go and read my previous article linked above to find out safe roundabout designs.
Dangerous roundabout designs are a continuing issue in the Netherlands
Data from the Smart Traffic Accident Reporting system has been used to create a map which shows the most dangerous roundabouts in the Netherlands. I’ve picked out below some of the Dutch cities which I’ve written about before and shown how they rate for roundabout safety:
The interesting thing about the map is that it so strongly reinforces the data which I based my previous blog post upon: Assen’s 21 roundabouts almost never cause any crashes at all. When there is a crash it usually results only in minor bodywork damage to cars. Between 2014 and 2017 there were just eight minor crashes with material damage to cars between all the roundabouts in Assen. There were no injuries. Annual crash rate: 1 for every 32000 population, Injury rate: 0
The safe design is well established and has a proven track record. It also is naturally resistant to error in implementation due to imperfect copying of the design, making an ideal basis for other countries to create their own safe roundabout designs for cyclists.
The “priority” design is proven to cause a significant level of injury to cyclists in the Netherlands and even here is misinterpreted quite often in such a way that it is more dangerous than it need be and causes significant inconvenience to cyclists, as shown in the video above.
The roundabout design which should be copied by countries outside the Netherlands is therefore the safe roundabout design. Copy what is proven to work, not merely anything that is “Dutch”.
On our study tours we demonstrate the difference that good infrastructure makes. Roundabout designs are included.
