The pavement marking to the right, which is supposed to tell people where to place the wheels of their bike to trigger a green light, is illegible to about half of Portland bikers, a new study (PDF) finds.
Even worse: Those figures don’t include many people who rarely ride, suggesting that interminable red lights are a particular burden on new bike riders.
Stefan Bussey, a PSU civil engineering student who conducted the survey, said he came up with the idea when he noticed that people ahead of him at the long Seven Corners traffic signals on Southeast Division would regularly stop a few feet away from the traffic signal stencil.
“It would happen three or four times a week,” Bussey said.
Bussey’s research confirmed it: even in Portland, about 55 percent of bicycle riders surveyed don’t know the meaning of the pavement marking.
