Bay Area transit agencies coordinate the Big Sync to unify schedule changes

Bay Area transit agencies are now syncing schedules in a whole new way with a focus on improving transfers between systems and making schedule changes at the same time. Transit riders who use more than one system will see a variety of improvements across the Bay Area this month, saving some riders up to 16 minutes on their trips.

Many Bay Area transit agencies are rolling out new schedules mid-January in coordination with each other and have now aligned the timing of schedule changes twice each year, once in summer (mid-August) and once in winter (mid-January). Since 2022, the number of transit agencies with full schedule change alignment (changing schedules at the same time in August and January) has increased from four to 20 - a 400% increase.

Advancing schedule change alignment is a key priority for Bay Area transit general managers who meet on a weekly basis to make transit more rider-focused and efficient. 

The Big Sync reduces travel time

Agencies meet several months in advance of each schedule change to share planned changes and to look for opportunities to improve transfers.

Specific service coordination efforts for January include:

• BART is timing its late evening Millbrae service that runs every 15 minutes to line up with Caltrain's service every 30 minutes. In September 2024, Caltrain's new electric service schedule significantly improved transfer times. Both agencies have coordinated on a helpfultransfer timetable to show which trains connect and their transfer wait times.  
• VTA is making changes to match both BART's and Caltrain's schedule changes to ensure timed transfers are maintained at various locations across the South Bay and Peninsula.
• In San Francisco, Muni is restoring the 30X Marina Express bus for two morning trips at 7:15am and 7:45am, beginning in February. Morning commuters will be able to enjoy a fast, direct connection from the Marina to BART and the Transbay Center connecting to various bus lines.
• For transit riders traveling during the morning commute from Napa County's Redwood Park n Ride on the Napa Valley Transportation Authority's bus 29 to El Cerrito del Norte Station to catch the Red Line into San Francisco between 5:30am and 8am, their trips will be six minutes faster on average and up to 16 minutes faster.
• For transit riders returning home on their evening commute from the San Rafael Transit Center in Marin County to the Richmond Parkway Transit Center in Contra Costa County between 3pm and 6:30pm on the Golden Gate Transit #580 or #580X and the AC Transit #76 (transferring at Cutting Blvd and Harbour), their trips will be 5 minutes and 40 seconds faster on average and up to 16 minutes faster.
• Transit riders departing the Salesforce Transit Center between 9pm and midnight on the Golden Gate Transit bus 130 and the Marin Transit bus 35 (transferring at the San Rafael Transit Center), will arrive at the Canal Area of San Rafael (Kerner and Larkspur) 15 minutes faster.

"These are examples of how Bay Area transit agencies are acting as one network to better serve the Bay Area to help reduce traffic and improve the quality of service," said Alicia Trost, Chief Communications Officer at BART. "Making transit faster than driving a car and easier to navigate is possible when the Bay Area invests in transit and we all work together." 

Bay Area Transit in 2025 is anything but business as usual 

Riding transit will be more affordable in 2025 as Bay Area transit agencies are working with the Metropolitan Transportation Commission on the upcoming Next Generation of Clipper, which will give transit riders free or discounted transfers between systems. A unified approach to maps and directional signs across the region is also being tested and expanded. And agencies are participating in Clipper BayPass to test the concept of a prepaid unlimited transit pass and fare capping. Clipper BayPass is being sold to interested organizations who would like to offer their employees an all-you-can-ride transit. These programs will help increase transit ridership and will help meet local and state climate goals.
