On Church Street in San Francisco near the intersection of Market Street — a nexus of light rail, streetcar, and bus lines — a simple but potentially transformative street improvement was put in place over the weekend. The center lanes of Church Street between Duboce Avenue and 16th Street were painted a bright, fierce red, signaling that these lanes are prioritized for transit and taxis.
The painted lanes are a preview of the commonsense flavor of improvements that the SFMTA’s Transit Effectiveness Project (TEP) proposes to implement as a means of improving travel time and reliability on the “Rapid” network. This network includes Muni’s most heavily used routes, including the J-Church and 22-Fillmore, both of which use Church Street and experience among their most crowded loads on this particular segment where the two routes overlap. If the center lanes are kept clear of cars with a combination of visual cues, signage, and enforcement, transit vehicles can access boarding platforms more promptly while motorists use the outer lanes. The transit-taxi lanes are coupled with restrictions on left turns between 7:00 a.m. and 7:00 p.m.
The Church Street project does not address any number of other pinch points and constraints that impact the quality of J-Church and 22-Fillmore service, but it is characterized as a “pilot” because it gives the SFMTA, even before environmental review for the TEP is completed, an opportunity to monitor how this type of street treatment performs in a confined area — a microcosm with different transit vehicles, as well as a mixture of commercial activity and residential driveways. The bright color literally gives more visibility to the SFMTA’s efforts, and with over 15,000 riders passing through this short stretch of Church Street each weekday on the J-Church, 22-Fillmore, or 37-Corbett , a substantial number of people stand to benefit from the pilot, while also getting a small taste of what is in store.
This part of town has become something of a TEP preview showcase, first with the more spacious boarding areas built for the N-Judah, and now with painted transit lanes joining the mix. Each one of these improvements taken unto itself may be small in scope, but when implemented incrementally at key locations throughout the city, collectively, they can make a tangible difference at relatively low cost.
 This reflects only the lines that use Church Street. It excludes the F-line and Muni Metro subway and thus represents only a portion of the total number of transit riders that pass through Church & Market each day.
