It does still have a separate crossing for pedestrians but for some reason this arm does not indicate to drivers that pedestrians should have priority. Why ? I have no idea. No explanation at all for this. To me it seems like an oversight.<br /><br />The Melbourne example is David Hembrowhttps://www.blogger.com/profile/14543024940730663645noreply@blogger.comtag:blogger.com,1999:blog-3102538965694240940.post-70673510568151146252019-03-13T20:44:59.436+01:002019-03-13T20:44:59.436+01:00Hi David and thank you for your informative blog. ...Hi David and thank you for your informative blog. I noticed in the Nobellaan-Thorbeckelaan example that three arms have zebra crossings but one does not (which is the closed to a school too) and wondering why this is the case?

I'm not sure if you've seen all 21 of Assen's roundabouts (<a href="http://www.aviewfromthecyclepath.com/2011/09/every-roundabout-in-assen.html" rel="nofollow">you can find them here</a>). All of them, including the roundabout highlighted above and in 2014, are in an urban context, within the city. I choose that one to highlight because it is David Hembrowhttps://www.blogger.com/profile/14543024940730663645noreply@blogger.comtag:blogger.com,1999:blog-3102538965694240940.post-87267052401521179432018-05-16T05:44:44.339+02:002018-05-16T05:44:44.339+02:00Thanks for this thoughtful post.

(By the pics/vids the other ones don't seem significantly different in size to me.) Do you know of examples in a smaller and/or urban context?<br /><br />We have a similar problem on a Melbourne intersection at the moment (https://goo.gl/maps/hardcoderhttps://www.blogger.com/profile/00531272518893233175noreply@blogger.comtag:blogger.com,1999:blog-3102538965694240940.post-88233106220727814172018-04-26T11:47:41.937+02:002018-04-26T11:47:41.937+02:00That's part of it.

Not relying upon drivers to take decisions which maintain the safety of cyclists but giving that control to cyclists themselves.<br />3. Adverse camber for cars going around the roundabout to slow cars down.<br />4.
