green gravel traffic islands
- On the corner of Michigan Ave & Washington Blvd in Pasadena, they have placed green gravel ?islands?
?peninsulas? These patches of green protrude into the street 3 feet from the curb. Effectively, making
Michigan Ave neckdown at the intersection. Isn't this where one would like a wider street?
What are these called? And did the decision makers ask for bicylists comments.
- I don't Know what the city's up to, but I just rode up Michigan and
there's another one, even wider, at Orange Grove.
It looks like a quasi "curb extension". Curb extensions, (usually
concrete curbs,) are used to narrow intersections to improve
pedestrian safety by reducing crossing-times and car turning-speeds.
The one on Orange seems to be correcting a too-wide radius on the
corner, the one on Washington looks like short sight-lines could have
instigated this application; but my best guess is that neighbors
complaining about short-cutting commuters driving too fast on their
residential streets is most likely, because Michigan is a fairly
un-interrupted cut-through street.
My biggest criticism would be that the green gravely-stuff could
compromise traction on narrow bicycle tires; but after a while all
that loose stuff will be gone anyway. Mostly it looks experimental
and temporary, I bet it's part of a study to see what works.
There are similar treatments where they did quasi curb extensions but
by using botts-dots, at Lake and California, on Los Robles/Cordova
and again at Del Mar or California. There are a bunch of actual curb
extensions along California East of Hill.
There are people on this list that might know more.
