I posted a picture on twitter and it received questions and feedback that don’t fit in a tweet. Here you go, here’s the latest revision of it:
(The back story: I posted a picture on twitter from Cycle Superhighway 5. Somebody responded to it with a vacuous slogan about how roads should be for all transportation types. I was flippant: “we tried that and it didn’t work”. They responded that there were still plenty of options to try before resorting to protected Cycle Superhighways.)
So in answer to the Qs:
1. Yes, these positions on the graph are all just things I’ve made up with 2 minutes thought, but they are based on 8 years of looking at these things. Want to know why I’ve placed items where they are? The Cycling Embassy Canards pages are a good place to start, then Crap Waltham Forest’s what won’t bring about mass cycling series and David Hembrow’s what not to do posts. Your tweets have done nothing to change my verdict on “strict liability”, 20 mph limits or Bikeability training.
2. Because, whatever the merits of strict liability or training, the issue at the heart of the original discussion was: what will remove barriers and enable cycling for all demographics, making it a genuine option and creating the conditions for mass cycling to improve our cities and supply our transport demands? So this concentrates purely on that outcome. Policies can have other outcomes too, so, yes, 20mph limits are a good thing worth campaigning for — but because of the sum of the outcomes, not because they will enable mass cycling.
3. No, the fact that something’s in the “not happening any time soon” category doesn’t automatically disqualify it from being worth asking for. Because, if you use the tactic carefully, going in with a big ask can make it easier to achieve a smaller one: we got the relatively small but very worthwhile victory of Cycle Superhighways by blazing in with the big ask of Go Dutch. And once the Cycle Superhighways are open, Go Dutch itself will creep ever higher towards the plausible region.
Your assessments may vary. Go ahead, make a copy and do with it whatever you like.
