Caltrans District 4 Transit Plan
About
The Transit Needs Assessment (TNA) is now available! As a part of the Caltrans Bay Area Transit Plan, the TNA identifies areas along the State Transportation Network (STN) where increased investment in transit-supportive facilities could be the most impactful to transit service.

The Caltrans Bay Area Transit Plan identifies infrastructure improvements and district-level best practices and strategies that can increase transit reliability, access to transit, and encourage more transit use along the STN.
Together, the Transit Plan and the TNA provide a framework for District 4 to support the Caltrans Director’s Transit Policy (DP-40) goal of improving transit service and access on the STN.

An inventory of existing transit-supportive facilities on the STN.
District-level goals, objectives, and performance measures for transit-supportive facilities, with an emphasis on equity.
Strategies and actions for Caltrans Bay Area and local and regional transit agencies to streamline the development of transit-supportive facilities.
A Complete Streets Transit Toolbox of best practices, common standards, and types of transit-supportive facilities to consider on the STN.
What is the Complete Streets Transit Toolbox?
The Complete Streets Transit Toolbox was developed by Caltrans District 4 to provide information to assist local and regional transit agency and Caltrans project staff (including planners, project managers, engineers, designers) looking to build infrastructure along the STN, including transit priority and transit access facilities.

Transit priority facilities help create faster, more reliable transit. Some types of facility improvements outlined in the toolbox include lane treatments and signal priority treatments.
Lane Treatments
Lane treatments consider not just transit movements but also coordination with other modes including biking, walking, and motor vehicles.
Dedicated Transit Lane
HOV Lane for Transit
Queue Jump Lane
Signal Priority Treatments
Signal priority treatments include special signal timing strategies and/or infrastructure that support transit operations at signalized intersections. Transit Signal Priority systems can be hardware-based (as show below), centralized or cloud-based.
Transit access facilities improve the experience of transit users by providing accessible, comfortable, infrastructure for pedestrians and bicyclists to access transit stops.
The Toolbox provides guidance for infrastructure such as:
Bus Stops, Freeway Access Stations, Bus Bulbs, and Bus Boarding Islands
Bus stop amenities like shelters, shade, seating, lighting, platforms, real-time next-bus arrival information screens, and emergency response buttons
Pedestrian and Bicycle Access
Wayfinding
Mobility Hubs

What is the Transit Needs Assessment?
The TNA identifies and tier’s locations along the STN where increased investment in transit-supportive facilities could be the most impactful to transit service. Tiering “location-based needs” will help Caltrans Bay Area make informed strategic decisions about how to allocate resources and efforts that improve the STN, supporting local and regional transit systems in the Bay Area.
District 4 coordinated with Caltrans Headquarters, local and regional partners, and transit operators to align the location-based needs assessment with statewide priorities, local needs, and existing conditions. The final TNA is now available for the public to view.
