ABOUT

What was this project about?

Although Tri Delta Transit is providing more hours than before the pandemic, ridership is still significantly lower due to the shift in commuter work schedules. Revitalize Tri Delta Transit project listened to the challenges riders were having matching an old system with their new work and lifestyle patterns, as well as hearing from potential riders why they did not ride currently. Revitalize Tri Delta Transit is the opportunity to rebuild and update the transit network for our current riders, especially transit-dependent riders, make the system more efficient to rebuild and increase ridership, and provide transportation options for the communities we serve.

FREQUENTLY ASKED QUESTIONS

RECOMMENDATIONS

Your input helped shape the New TDT Network.

Feedback from riders, community members, and Tri Delta Transit staff was used to develop the New TDT Network that is focused on reducing duplication of service, improving weekend service, and increasing frequency.

Specific benefits of the New TDT 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
Maintain as much of the current coverage as possible for existing riders, while increasing bus frequency
Expanded Tri MyRide – replacing fixed-route service

Why Change Service?

The routes in today’s network are long, indirect, and have frequencies that are inconvenient for most riders. The New TDT Network makes service faster, more direct, and offers higher frequency routes that better meet the needs of the communities we serve. These changes directly align with the top priorities we heard from riders and members of the community during public engagement.

All of today’s routes create challenges for current and potential new riders. The New TDT Network, with service every 30-minutes, creates lower wait times for existing riders, provides better connectivity to BART, and appeals to potential new riders.

Five routes will have 30-minute or better weekday service, which means more reliable service and more access to jobs for existing riders. This service change will improve access to jobs and provide better, more reliable service for existing riders. 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. The New TDT Network creates more direct service that reduces time spent on buses, resulting in faster service for existing riders.
