When bicyclists ask a Public Works Dept. to do something around a city, they often get the response “No we can’t, it’s not in the MUTCD.”
But what they’re not telling you is that there’s lots of approved signs and markings for bicycles that they can use, but they’re not telling you about it.
I’m presenting this as a workshop, Thursday Feb 17, Physical Sciences and Engineering Library, 4 – 5:30 pm. Come for all or any of it, and see all these mysterious documents for yourself.

The MUTCD is a long-winded, technical manual on what signs and markings can go on roads. It’s the “Manual on Uniform Traffic Control Devices.” The theory is that a all markings should be uniform, so a yellow stripe or green sign means the same thing everywhere. And its very car-oriented. Not much in there for bikes.
Fortunately, the MUTCD *does* have a modest number of signs and designs that bicyclists can ask for, and receive. Many “problems” on bikeways and with bikeway designs are where the designs are out of compliance with standards. These problems can be identified, reported, and Public Works will happily fix them.
Bikeway design standards are scattered through a half dozen different plans and design manuals, the MUTCD and others. If you want to get something built or something changed, it’s helpful to know what’s in the manuals and what isn’t. On Thursday we’ll wander through all these documents to see what they have, and what they don’t have, and everyone will have a better idea as to what they can and can’t specify in bikeway improvements.
It’s fun, it’s empowering.
Afterwards we’ll ride around Davis and see what’s in compliance and what isn’t. Bring a tape measure, camera, or other useful measuring and reporting devices.

We’ll look at a few of these — some are only available electronically, but there’s enough of them with hard copies that you can get a feel for the whole family of documents.
