Like I wrote yesterday, I'm learning a bit about how to use Google Fusion to make maps. I wanted to learn more about how to work with boundaries, census tracts in particular, so I made this map which shows the bicycle mode share of every census tract community in Los Angeles county. As with the crowding map it's a work in progress, but let me know if you'd like any additional information or can think of ways to improve its readability or usefulness.

My initial intent was to find if this gave any indication of where we might want to prioritize investments in the bicycle network -- basically if there were already existing corridors of high bicycle use. Some clearly exist, like that from USC to Downtown (Support MyFigueroa!), around North Hollywood, and, more surprisingly, up in the Valley around Cahoga Park (which I admit to knowing nothing about). Likewise, Santa Monica's large bicycle mode share is no surprise while Whittier's was a little unexpected.

Anyway, check it out for yourself!:
