Twenty’s plenty

April 20th, 2009 Posted in Road news

We return to business as usual with a story that large-scale rollout of 20mph limits is being considered as a solution to road safety concerns, particularly considering that in many areas targets for casualty reduction are not being met. In London, whole boroughs want to turn 20mph except on major roads. Oxford is heading that way and Portsmouth has already done it.

I am not going to rant and rave about lowering speed limits, the motorist being the victim, another infringement on our liberties by a car-hating government and all the rest of it. Nor am I going to rail against speeders and implore you to please think of the childruuun. I do get annoyed with inappropriately low speed limits, having me chug along at 30 when there’s no obvious justification for it, and I also get upset when I see people travelling inappropriately fast. In other words, I’m not really in either of the traditional mudslinging camps of the speed limit debate.

My view is that widespread 20mph limits will not prove to be the wonderful fix-it solution that campaigners and politicians are hoping for. My experience is that a small, well-placed 20mph limit or zone can make you sit up and pay attention - effectively and subtly highlighting an extra risk. A big, rambling 20mph zone is largely forgettable and not worth the effort.

I say this from the point of view of someone who lives on a 20-limit road, speed cushions and all, and who sees the effect it has: none. Cars and vans do 30 to 40 down the street. Buses do 30 in between stops. I’ve followed police cars above 30 (and there are plenty, with a police station on an adjoining street). Nobody - authorities included - pay it the slightest bit of attention. And that is my problem with 20 limits: not that they are wrong in themselves, but that they do not automatically work. The one I live in doesn’t work - traffic speeds are anything up to double the limit and it is therefore patently not saving any lives.

It’s easy to make comments from the sidelines and not so easy to continually improve road accident figures, which is what the creators of this scheme are trying to do.

I would suggest something slightly more expensive but substantially more… well, substantial. I would re-paint streets like mine to organise the on-street parking differently, using the parked cars to reduce forward visibility and create a chicane effect, which would force traffic to move more slowly and carefully (and not incidentally, would allow people to park head-on to the kerb, increasing the number of spaces and giving me half a chance of parking within five minutes’ walk of my front door).

That’s all I’m saying - not that it’s bad, just that a 20mph restriction on its own will not magically alter things. Much better to consider why the street is carrying fast traffic than just apply another rule to be ignored.

  1. One Response to “Twenty’s plenty”

  2. By David on Apr 22, 2009

    Absolutely. The most annoying (and ignored) speed limits are those applied without any justification. For example, Bristol City Council recently widened Newfoundland Road from the bottom of the M32 (J3) into the city centre. To pretty much all observers, it’s still part of the motorway, as it is a dual carriageway with 2 lanes each way (now with an inbound bus lane for good measure), a service road on the west side, narrow hard shoulders and is crossed by a large pedestrian footbridge.

    So after the delays caused by the improvement work, what happens? They reduce the limit from 40 to 30mph - this being the same limit as the residential access road next to it. There are no pedestrians, no buildings and no flat junctions. Apart from rush hours, the motorway goes along quite nicely at its 60mph limit just north of here, and the traffic lights at the end of the road are well signed and very obvious. Why change a speed limit to make a narrow residential road as viable a route for traffic as the dual carriageway?

    For that matter, why put full-time traffic lights on a roundabout interchange (J3) when they’re only needed for about 20 hours a week?
