Roundabouts in Europe: 2017 edition

One year after my 2016 post Roundabouts in Europe, it’s time for a little follow-up. As stated in Répartition des ronds-points en France : édition 2017 (in French), I have updated my methodology in order to get a more accurate account of roundabouts, based on OpenStreetMap data.

The main methodological change is that I now take into account what OpenStreetMap calls « mini-roundabouts« , that are stored as points instead of ways (like standard roundabouts). Mini-roundabouts are « a special type of roundabout in which the middle can be traversed by vehicles » and represent a significant part of all roundabouts in some places.

I have studied the same 20 countries than last year’s post, plus Iceland. Here are the results:

densite_rondspoints_NUTS0
Roundabouts density in Europe, per country. Displayed values represent the total number of roundabouts. OpenStreetMap and Eurostat data, August 2017.

France still holds the record of roundabouts density, by far. Our newcomer, Iceland, contrasts with Nordic countries since its roundabouts density is comparable to Portugal and Spain!

Country Roundabout number per 1,000 inhabitants (2016)* Roundabout number per 1,000 inhabitants (2017) Roundabout number (2017)
France 0.91 0.94 63,212
Portugal 0.79 0.84 8,630
Iceland 0.81 273
Luxembourg 0.80 0.80 472
Spain 0.77 0.79 36,762

(*) re-calculated with the new methodology

Regional divides are interesting to notice: East/West division in France and Switzerland, North/South in Italy and Belgium (it looks like Francophones really like their roundabouts). It is also remarkable that all capital regions seem to have a lower roundabouts density than their immediate neighbours (Paris, Madrid, London, Lisbon are particularly noticeable).

2016 – 2017 evolution

Finally, let’s compare the density of roundabouts country-wise. Only two countries are experiencing a decrease in roundabouts density – although their absolute number of roundabouts is still increasing: Ireland and Luxembourg.

There is no clear overall  trend: some of the fastest roundabouts-building countries have relatively low roundabouts densities in the first place (Poland and Slovenia), whereas Portugal keeps running for the first place.
