While this new Stanley Roberts segment  about transit lane enforcement with bus-mounted cameras spends a lot of time exclaiming about the fines for drivers, the fact is that San Francisco needs much more bus lane enforcement to really keep transit running smoothly.
San Francisco’s limited 17-mile network of transit-only lanes  generally isn’t marked very clearly, and enforcement was virtually non-existent before Muni installed 30 bus-mounted cameras in 2009. The pilot program, which sends fines to violators by mail, is slated for a much-needed expansion  to 300 buses early next year.
To help make transit-only lanes more intuitive, the SF Municipal Transportation Agency also plans to expand its use of colored bus lane treatments, starting with a pilot project on Church Street  set for implementation any day now (the latest construction schedule was delayed by rain in November). New York City has been expanding colored bus lanes recently in conjunction with camera enforcement and other improvements on its Select Bus Service routes , which have improved travel times by 15 to 20 percent on some of the highest-ridership bus lines in the nation. Muni plans to implement similar improvements on eight priority routes in its Transit Effectiveness Project , though they’re not set to go in until 2014. Physically-separated, colored transit lanes will also be used on the Geary  and Van Ness  Bus Rapid Transit  routes.
The SFMTA has to keep on expanding the use camera enforcement and well-marked transit lanes to save Muni riders from getting bogged down behind double-parked cars.
