What is missing from this graphic?

With lots of little bits and pieces of road and rail infrastructure funding announced in the autumn budget statement, I thought it was about time to get around to assembling the transport costs comparison infographic that has been on my todo list for months. I keep hearing all these millions and billions getting spent, but I’m no good at imagining what that amount of money means.

The format is nicked from the XKCD radiation infographic (subsequently also applied to money). I considered the option of having separate orders of magnitude — millions and billions — but in the end decided it was probably more helpful as a comparison tool with everything on the same scale.

I’ve actually only included a few of the Autumn Statement projects, because they turned out to be a bit boring when compared with a lot of the other projects and numbers I gathered. And I’ve not been very meticulous in my research or fact checking — this isn’t intended to be a perfect scientific dataset, just a quick way to see big numbers in context. The idea is that when Boris Johnson says he’s really doing a jolly lot to encourage biking in the outer boroughs, you can see that his fund for biking in the outer boroughs is about four times the size of the budget for a one day Zone 1 bicycle ride, and a bit less than the budget for a fancy Zone 1 pedestrian crossing. When Norman Baker tells you that the coalition is committed to local sustainable transport, you can see that their fund for it is only slightly larger than the electricity bill for London’s traffic lights.

Indeed, a few of the figures are really quite dodgy — the pavement parking costs, which were extrapolated as a mere thought experiment by Pedestrian Liberation, and of course the estimated costs of crashes, air pollution and obesity, which all rely on all sorts of questionable assumptions and on inventing market values for things that can’t have market values —¬† but I thought that it might be worth seeing them anyway. The final version would be accompanied by a long list of references and footnotes. (The graphic itself should also be a bit tidier!)

I’ve included all the numbers that were of interest to me and could found within a couple of minutes with Google. What else should I have included? What have I got wrong?
