Twin Peaks for All: Survey Results By Benjamin Barnett Last month, the SFMTA and San Francisco Recreation and Parks Department released a survey seeking public feedback regarding  five proposed roadway options for Twin Peaks Boulevard .

Muni Forward Gets San Francisco Moving By Shalon Rogers The SFMTA’s Muni Forward program is delivering transit reliability improvements that are transforming the Muni system and enhancing the customer experience. With 80 miles of upgrades since 2014 that often bring travel time savings of 20% or more, Muni Forward is making a big difference in how San Francisco moves.  These upgrades, which can be seen in this Muni Forward Photo Map , draw from a “toolkit” of over 20 reliability and customer experience improvements, such as transit lanes that provided dedicated space for Muni vehicles to cut through traffic, transit bulbs that reduce delays at transit stops and traffic signals with transit priority that give the green light to transit vehicles as they approach the intersection, when possible. The recently completed Van Ness Improvement Project thrust Muni Forward back into the spotlight with San Francisco’s first Bus Rapid Transit (BRT) corridor. While the Van Ness Improve...
