What is this project about?
Revitalize Tri Delta Transit is a comprehensive analysis of Tri Delta Transit’s transit system, which will take an in-depth look at the existing bus service in East County to improve it for those who rely on it most.
Although Tri Delta Transit is providing more hours than before the pandemic, ridership is significantly lower. This is partly due to a shift in pre-pandemic commuter work schedules. Revitalize Tri Delta Transit provides an opportunity to rebuild ridership by updating the transit network so it reflects changing transit rider needs – especially among transit-dependent riders.
Your input helped shape these recommendations.
Feedback from riders, community members, and Tri Delta Transit staff was used to develop recommendations focused on reducing duplication of service, improving weekend service, and increasing frequency.
Specific benefits of the Recommended Network include:
-
Consistent, higher frequency in high ridership areas
-
Faster, more direct bus routes to major destinations
-
Better connections between buses and BART
-
Less duplication of service with BART and other Tri Delta Transit Routes
-
Better weekend service
-
Almost all current customers still have access
-
Expanded Tri MyRide – replacing fixed-route service
Why Change Service?
Almost all of today's routes have frequencies that are inconvenient for potential customers. Service every 30-minutes has been shown to attract more customers due to lower wait times and better connectivity to BART.
Five Routes will have 30-minute or better weekday service. The number of residents, jobs, low-income residents, and minorities with access to 30-minute service improves by over 500% under this plan.
Travel times on many of today's routes are uncompetitive. A trip between Antioch and Pittsburg / Bay Point can take more than 2 hours on today's alignments. This plan creates more direct service that reduces time spent on buses, making service more competitive.
