This is an example of a fairly common intersection and roundabout treatment that is employed in inner Newcastle suburbs. The squeeze point that is created by the narrowing of the road is not friendly to cyclists. And above is an example of a similar measure being used as a traffic calming device in Inner Sydney, also creating a squeeze point that is not cycle friendly, except that it may keep cyclists a little more clear of the car door zone that soon follows it.
In this post, David Hembrow talks about how the Dutch treat roundabouts for cyclists, and while the examples he gives are for the treatment of much larger rounabouts, a similar treatment can be applied to smaller roundabouts, such as the one in the first photo of mine. The gist of the Dutch solution is to create a pathway for cyclists that is separate from the rest of the roundabout traffic because it is situated a few metres outside of the traffic way of the roundabout. Using the above type of infrastructure, a much safer path can be created, using the traffic island, for cyclists. Cyclists would be separated from cars using the roundabout. The dangers are that cyclists may have a false sense of security about their right of way when using the roundabout, as they would still be required to give way to traffic approaching on the right. The drawback of having the cycleway too far from the intersection is that this could happen … … where cyclists have obviously been choosing the shortest path through Newcastle’s Civic Park to ride. If this happened it would render the cycle path through the intersection redundant.
