[SDCBC] Portland Crash Rates [was Now playing on YouTube - The Rights and Duties of Cyclists]

[Stephan Vance]

I know the Bicycle Coordinator in Portland, and I know he has studied the
European approaches to bike transportation, so I expect he is aware of the
data from Copenhagen and elsewhere. In any case, despite the reported
increase in bicycle traffic in Portland, the city has experienced no
significant increase in bicycle crashes. Here's the chart that shows the
declining collision rate at the bike traffic increased. It's a little
speculative because the usage data is from four river crossing points and
the crash data is citywide, but I think the point still is made.

Thanks for forwarding Schubert's message, Serge. The first paragraph below
should be required reading in Portland OR, while the final paragraph further
reinforces my own call for general traffic calming and speed limit reduction
on prime arterials, because the current crop of neiborhood electric vehicles
is restricted to streets with posted speed limits of 35mph or less,
rendering them pretty useless in most of San Diego County.

... Note that Copenhagen reported a 30 percent increase in the accident rate
from their cycle tracks; Berlin reported a sharp uptick in accidents
when they installed sidepaths; Toronto has documented a large
percentage of dooring accidents.

-- Roads of the coming century will accommodate an increasingly strange
mix of vehicles.  I'm waiting for small-displacement motorcycles to
come back; they're extremely widely used in many other countries.
Electric versions of same become more and more practical every year.
The Twike (side-by-side human/electric powered faired recumbent) and
similar machines are waiting in the wings.  Every month, Popular
Science seems to have a story about another machine that's somewhere in
the continuum between roller skates and the traditional car.  Many of
these devices are closer in speed to a bicycle than to a regular car.
Are we going to build special lanes for all of these categories of
conveyance?  No, and I sure hope we don't even try.  From the
standpoint of making viable public policy to accommodate all these
conveyances safely, I believe we already have a superb plan in place:
one set of rules, with speed positioning and destination positioning by
individual need.
