Chevrons for All

In doing a little more research on sharrows, I came across a brand-new (only two weeks old!) study on sharrows done by the city of Bellevue, Washington. It's worth a download and read. Much of the methodology is very similar to the earlier City of San Francisco (CSF) study.

Continuing in the spirit of my last two posts, I've decided to do a little "free art" for the public. I've made a couple of full-size graphics of chevron-style sharrow images, done to two different municipal standards. They are ready to be printed on a large-format printer and cut into a large sheet of (something). Then, well, do with it as you will. Hang it on the wall, or use it, uh, as a focus for night-time activity.

Images: The images are full-size PDF graphics. They are fairly compact (in terms of file size). The image based on the CSF "chevron" style (download here) is smaller and will fit into a 4' x 8' sheet of stencil material. The Bellevue image (download here) is rather larger and would require a 4' x 11' or 4' x 12' sheet of material. I've slightly modified the CSF image by adding "webbing" for easy positioning of the cutouts. This will be a single-piece stencil. The Bellevue image isn't modified from their spec, which is much more detailed, and is a multi-piece stencil.

Positioning on roadway: The CSF guidelines were for the center of the image to be 11'-0" from the curb in areas of parallel parking. The Bellevue guidelines call for the center of the image to be "about 11 feet from the curb where parking exists" and, with no parking, "about 3 feet out from the curb."

Methodology: Well, the standard approach is to print the PDF full size at a printing shop that handles large-format printing, then to transfer it to stencil material such as corrugated single-face plastic sheet and cut it out (be careful, be careful, BE CAREFUL!)

It is, however, difficult to get an image out of my head, and that is Joshua Kinberg's utterly brilliant "Bikes Against Bush" rig (website here, video here) done for the New York City Republican Convention. The resolution of these images are of course a lot higher than the rather crude (brilliant! but low-rez) letters of Joshua's first experiment. But it doesn't take a genius to visualize a higher-rez "bike dot matrix" system that could handle one-color graphic images as well as just text. This really sounds like a job for JK or the Graffiti Research Lab of NYC. This would be a technological tour-de-force for the "Urban Repair Squad", wouldn't it?
