It would be useful to define 'towns and cities'.
Yes, that would be useful. Just as a starting point, I can think of three types:
- actual town and city centres, where there is a high density of "destinations", usually a lot of pedestrians, and very little space available;
- long distance routes, often served by motorways, but including some big A roads that haven't been bypassed by motorways;
- roads that connect suburban conurbations and towns with cities, but which often pass through smaller town centres.
Since the 1960s most such places have seen a desertion of the centre for the suburbs. If you believe town centres can reasonably avoid cycleways and adopt 20mph speed limits and road cycling I'm with you all the way.
Good, we are agreed on that, at least.
Unfortunately the overwhelming majority of 'city' dwellers are suburbans who have to negotiate the excesses of post-war highway development.
Those suburban roads are extensions to the national highway infrastructure with lorries making deliveries to supermarkets, skip wagons, car commuters and the rest who have come to expect 50mph+ travel with the odd 40mph zone, within highway engineering designed to encourage their belief in such space as fast road transit zones. To make such areas cycle safe would require a reduction of all such zones to 20mph. I'm all for such an initiative but it would require a shift in mindset at least as great as contemplating Dutch style bikeways everywhere.
But nowhere near as expensive to implement.
We are talking particularly about category 3 above, here. I think an issue with these roads is that a lot of traffic uses the A road when there is a perfectly good motorway, which might be a slightly longer route, but is much more appropriate.
It would mean mid and long distance private and commercial motor transport times doubling or tripling as drivers encounter a succession of 20mph main roads, with the financial implications that go along with it.
I doubt this. I often see the same vehicles several times on the one journey, even though their top speed is well in excess of the 30mph speed limit, and my average speed in about 15mph.
If you believe that picture is an exaggeration of the requirements for safe utility cycling then you have to accept that speed differentials in large areas of the city (as well as existing highway engineering) make riding a bike a skilled enterprise with the low numbers who'll adopt such a mentally and physically focused activity.
I don't think anyone here is saying that the status quo is good. The argument is about the nature of the solution. I do agree with some earlier comments about not trying to come up with a one-size-fits-all solution.
What I am certain of, is that the cycle lanes on my route, apart from being sub-standard themselves, are useless with all the cars parked in them, and if parking were banned on the road, there would be plenty of width available to the extent that there would really be no need for a cycle lane.
