The SFMTA has proposed new forced turns for private autos at intersections on the most congested stretch of Market Street, which could be implemented in phases early next year. SFMTA staff presented the changes [PDF] to the agency’s board of directors Friday — not just as a way to speed up transit, but to make the thoroughfare safer for walking and biking.
The SF Chronicle reports:
“This is primarily a safety project,” said Timothy Papandreou, director of strategic planning in the sustainable streets division of the Municipal Transportation Agency…
The changes announced Friday include stepped-up enforcement of existing transit-only lanes and turn restrictions. Early next year, additional mandatory turns are to be installed at Third, Fourth and Fifth streets and transit-only lanes would be extended eastward down Market.
Market Street between Eighth and Montgomery streets has twice as many collisions as parallel Mission Street despite having only a third of the traffic, Papandreou said. It also includes four of the city’s 20 worst intersections for collisions that injure or kill pedestrians — Fifth Street, Sixth Street, Eighth Street and Main Street. Two of the worst intersections for bike collisions are also on Market at Third and Fifth streets.
The MTA will focus first on Montgomery to Fifth streets before considering whether to head farther down Market.
As we reported last month, the SFMTA is implementing near-term measures in the meantime, including re-timing traffic signals, painting the transit-only lanes red (an effort that began on Third Street last week), and installing ”Don’t Block the Box” paint and signage at intersections, all of which will come with increased enforcement by early summer.
