Hill's most dangerous bike stretch: E. Pine

Seattle PI's map of reported bike-car collisions in the city of Seattle shows the most dangerous stretch of Capitol Hill street to be E. Pine between Summit and Melrose. The red dots on the map below represent areas where there were 3 or more accidents reported for the four year period in the study, 2001-2005.

 

PI notes that many bike accidents go unreported. And near misses, of course, aren't in the dataset. But surely you have your freak-you-out intersections and corners. Where are your near-miss hotspots on the Hill?

You're not accounting for usage.
You need to divide the number of accidents by the number of cyclists to determine danger (an accident rate).

Pine is a very popular bike route, so it's not surprising there are many accidents there. But maybe there are fewer accidents per biker on Pine than elsewhere.

RE: You're not accounting for usage.
Yeah, agreed but impossible to measure except in our minds.

So, the one dude who tried to pop a wheelie and failed at Grandview and Garfield makes that the most dangerous place to bike per capita

Hee. Whenever I TA public health students, we always ask an exam question with identical data to test on their understanding of denominators when making statements about the "risk" of something. (Seriously, the PI must recycle this story every year and update the numbers.)

E Pine
With the dedicated bike lane and many cars turning right to hit the I-5 onramp, I'm not surprised there are more accidents there than elsewhere. There's been too many times in my personal experience where cars just swerve into the bike lane just ahead of me or into the spot where I am (forcing me to abruptly brake or pull off the road entirely) in order to turn. Remember when you're driving to check your mirrors and blind spot before turning.

The worst stretch for me is actually 15th, and not because of the cars. More pedestrians jump out from between parked cars from 15th and Republican to 15th and John than any other part of Capitol Hill in my opinion, and I can't recall how many times I've had to yell, ring my bell, or just plain swerve out of the way in order to avoid running them over.

Have a look at Aloha
We've speculated in the past about whether Aloha is a dangerous place to cycle.
I've always felt pretty safe there. The map bears me out:

Two accidents: 1 at 23rd, 1 at Broadway, none on the up and downhill sections where you might imagine traffic would be faster and more of a problem.

When I used to skate to work..
Pine and Boylston used to be where I had all my near-misses. It was mostly cars trying to cross Pine not seeing me or pedestrians expecting me to be to stop while cruising downhill at top speed.
