DIY Bike Route

Ever
wonder which paths cyclists naturally take through a city? Not
satisfied with the location or extent of designated bike lanes? Feel
like other street users are quick to dismiss the presence of cyclists?

"Contrail"
is a design concept that enables cyclists to increase their visibility
to cars, pedestrians, and each other. Conceived by Pepin Gelardi and
Teresa Herrmann, this frame-mounted device would allow cyclists to make
their mark on the street with faint lines of chalk. The rear wheel
spins a smooth trail of color onto the pavement as the bike whizzes
along.

Contrail leaves an impression based on the cumulative movements of many
cyclists over time (a more lasting variation on the BYO bike lane concept employed by the laser-projected LightLane). Its provocative visual language lies somewhere between sky
calligraphy, temporary street graffiti, and overlapping footprints in
the snow.

Gelardi and Herrmann proposed Contrail for the Power to the Pedal competition,
and are currently developing a prototype. They envision "a new cycle of
biking participation" in which the criss-crossing chalk ribbons would
pique curiosity, identify more popular routes, and inspire more
cyclists to hit the road.

Mission Street Transit Lanes: What About the Bikes?

|
Earlier this week, the SFMTA sent out a release with a progress report on the “Red Lane” paint (actually, a thermoplastic adhesive) they are applying, clearly marking lanes for Muni Streetcars and buses (and taxis): Early signs indicate success. Preliminary data shows transit-only lane violations dropping by more than 50 percent on some segments of […]

SoMa to Get SF’s First Protected Intersection…in One Direction at Least
