The San Francisco Municipal Transportation Agency (SFMTA) developed a new flier to inform motorists of the new curbside queue while awaiting their turn at the Arco station. The flier provides clear images of the correct and incorrect ways to use the line-up whereas an earlier version was limited to a photograph of what not to do. Interns began talking with drivers blocking the bike lane on Fell and offering them one of the fliers. I've heard reports that once one driver gets in the queue, others follow, but the practice remains far from the norm.
Interns can reach relatively few people during a one to two hour stint two days a week, but SFMTA regularly provides traffic advisories to the media. The new Arco access lane seems a prime candidate for a similar alert.
