Calculate bike safety from turns #118

Closed novalis closed 13 years ago

novalis commented 13 years ago

When a bike lane is on the left side of a one-way street, and a bus route on the right, it's safer than the other way around because the bus won't turn into the lane.

When a bike lane runs alongside (say) a park, it's safer than when cars can turn into it.

The first of these is not doable with our data, since we do not know what side of the street bike lanes are on.

The second one ought to be doable, but it seems likely to be a pretty big speed hit due to the way we're handling intersections right now. We would basically have to compute it on the fly at every intersection.

But it occurs to me now that cities are likely to simply declare that paths along the side of parks are bike paths, whether or not they put in painted bike lanes. So we can get this from the shapefiles.
