Bike-related articles

January 12, 2018

An internet bikey friend is a new-ish assistant professor of transportation, has a pile-o-books to read. I figured, why not skim off the best/most-interesting of everything I collected in Evernote over the last few years, and make a dump of it, perhaps some will be useful, perhaps it won’t.

An amazing summary of stuff

Stuff I wrote

These tend to include links to spreadsheets and source documents, should anyone care to check my work.

Hypothesized mechanisms for US safety-in-numbers.

Bike share does not need helmets. Per-trip, it’s a lot safer than driving. There are caveats and quid-pro-quos — but the Cs and QPQs have larger effect than helmets.

We subsidize driving, yes we do.

Videos of not-quite right hooks, in case anyone wants to know what they look like.

A graph, by zipcodes, of the cumulative US population density.

Distributions for trip distances, for commutes and trips and general, and also a cumulative graph of the distance traveled. TLDR=”Lots of trips are short, but long trips matter because they are long. Commutes are 26% of trips but 35% of miles.”

Various ways of looking at road damage. It’s not presented as well as I would like unless you’re comfortable with log scales.

E bikes in China (back in 2011 the boom was well under way)

Videos I made

Tortoise and hare. Biking is that much faster, zooming ahead is useless and unsafe (video)

A playlist of biking in the snow and cold, yes it is entirely possible, do be careful on the glass-smooth ice (there is another video where I fall on that ice; well-used road commuting snow tires are not good enough for ice).
