Great to see you coming to CA.

Hi Roger, we met at the NACTO reception during TRB. Lots of respect for the work in your state.

I got a copy but it’s still in the queue.

I have seen the Chicago study. One long busy street with multiple treatments.

I think there may be a local setting issue. I feel they work ok on slow streets for trailblazing but not on busier streets where riders stay in the door zone. But feelings are not evidence and should be proven.

CA police collision reports take the addresses of the drivers. ID info is supposed to be redacted from copies given to the public to preserve privacy but it’s not always done.

Behind TRB paywall. Used to be free. I can send a personal copy if you can’t access.

I wrote my version of the Forester story in a TRB paper a few years ago. First heard his name when doing early biking research in Davis. Another chapter of the book I will never write.

You almost always see Orcas on Alaska cruises in the panhandle areas. Orca this far south is very unusual.

I drove past on Spring St only about an hour ago.

Wow. I didn’t know it was out yet.

This new AASHTO bike guide should provide the level of detail for bikes. It may also reduce hesitation to employ. But it is a separate publication and not $ free. The graphic shows many non road design features such as continuous bldg faces,sidewalk adjacent, no driveways, no parking.

I think for the US that NACTO urban street design guide comes close. There might be an FHWA publication that I am not aware of. These guides are not as detailed as AASHTO and state guides. It will ultimately require merging of multiple sources of guidance and sorting of responsibilities.

@tracktwentynine.bsky.social is that yours on the cover?

Most of the traffic engineers on this platform ride bikes. Time is spent trying to get acceptance of new ideas from those who don’t.

I’ve been fooled before. Promise??!

I feel the same way. So I put a photo with some slight relevance in and get no likes. I guess I need to think it out better.

Impressive results. Next challenge is to get those in control to be aware of the results.
