traffic calming or traffic removal? an East Oxford example

One common objection to low traffic neighbourhoods is that reducing motor traffic isn't necessary, and that all we need is traffic calming to stop speeding. But even if traffic calming measures worked perfectly in reducing speeds — which they don't — high volumes of traffic are still a huge deterrent to walking and cycling, especially for children and slower or frailer adults. Traffic calming measures such as speed humps and chicanes also tend to induce stop-start movements, with rapid speed changes that are dangerous, and can force people cycling to merge with motor traffic.

As an East Oxford example, consider Cricket Rd and Rymers Lane, which together run 1.3km from Howard St to Between Towns Rd. There are fourteen sets of traffic calming measures here, mostly speed humps combined with chicanes but in a few places just one or the other. (See the photos at the end of this post.) No one would ever design a street like this; it's clearly been retrofitted to try to cope with levels of motor traffic it was never intended to carry.

There's a large park with several playgrounds directly on this road, along with a nursery (Flo's), a primary school (St Frideswide's) and a high school (St Gregory the Great); it's the catchment boundary for two other primary schools (Larkrise and St Christophers), with some children from each having to cross it to get to school. And it is supposedly part of a designated "quiet" cycling route connecting Cowley and Littlemore with the city centre.

It's quite obvious to anyone with experience of this street that all the traffic calming measures here don't really work. The chicanes provide some protection for crossing, though that's still dangerous as drivers often accelerate to get through them before vehicles going the other way. But the junctions are terrible to cross, especially the one with Littlehay/Cornwallis, where there's traffic turning in all directions. And the effect for anyone cycling is like going through a mincing machine, being forced to repeatedly merge with the motor traffic at the chicanes and being overtaken multiple times in between them.

My challenge to anyone opposing this being turned into a low traffic neighbourhood is: what's your alternative plan to make it safe for children to walk and cycle across or along this route, so they can get to school, to the park, or to their friends' houses? How do we enable older, frailer, or slower adults in the area to get out and about, to go to the shops, get to the park or visit friends?

It should be clear that adding more traffic calming measures isn't going to help.

The county council thinks all it needs to do is "encourage" people to cycle and deploy an app, which is such a farcical idea I don't even know where to start.

The only real alternative I can think of — to turning the area into a low traffic neighbourhood and blocking through traffic here as part of that — would be to accept the levels of motor traffic and redesign the route accordingly (effectively to upgrade it to a B road, even if not formally). This would involve putting in proper signalised junctions at either end and at the Littlehay/Cornwallis intersection, putting in two or three pedestrian crossings to support access to the schools and park, and taking out all the on-street parking to fit in proper cycle lanes. This would cost at least a million pounds and more likely two or three, and the result would still (because of insufficient width) be sub-standard as a main road.

To supplement redesign as a low traffic neighbourhood, this area also needs a School Streets scheme and planning to reduce driving to the school or shift it so the drop-off and pickup locations are more distributed.

Here are photos of all fourteen of the existing traffic calming measures on Cricket Rd/Rymers Lane, proceeding from north to south.

This is jury-rigged plastering over a massive mismatch between the street and its traffic levels, not the result of coherent planning. What should this street look like?

  1. The chicanes have an obvious flaw if you're thinking about pedestrians and cyclists - there is no way for a cyclist to avoid merging with traffic without putting pedestrians at risk.

    You could put a cycling cut-through between the bollards and the pavement, but then pedestrians are forced to cross three lanes of traffic - two cycle cut-throughs and the motor traffic - or cyclists get surprised by inattentive pedestrians.

    If the chicanes are needed to manage motor traffic, then you have to accept that this road is not suitable for pedestrians or cyclists, and that schools should not have gates on this road.
