Mark Wagenbuur shows in his Bicycle Dutch blog how roads in residential neighbourhoods in Utrecht are blocked with retractable bollards to stop car drivers using them as rat runs.
Essentially, a rat run allows a motorist to avoid a main road bottleneck, rush hour congestion or a busy junction. However, ratrunning makes the nearby side streets noisy and unsafe.
In 2013 I looked at a notorious South Belfast rat run, Strangford Avenue, which is used to bypass the Malone Road B23/Balmoral Avenue A55 junction.
The road surface of Malone Hill Park is very poor, undoubtedly worsened by the many additional drivers choosing the tree-lined back streets over the main road.
I have superimposed the Google Streetview from this junction in Utrecht, Netherlands, on this junction in Belfast. Utrecht and Belfast are very similar in size, but couldn’t be more different with regards to active travel and public transport.
Retractable bollards are placed diagonally across the junction. Allowing emergency and permitted maintenence vehicles across, but severing the rat run.
It would cut off the through route from Malone Hill Park to Strangford Ave. Or in the satellite image below separate the blue streets from the red streets.
To stop motorists choosing Malone Court as an alternative exit it could be made a one way towards Mount Eden Park, marked with a black arrow.
Retractable bollards are expensive to install and maintain. But I can see little need for them to be retractable at this location.
It is an idea worth exploring. We all want peace and quiet? We want our streets to be safe? And bollards, should they prove not to work at this location, can be removed easily.
