AB 1599 California Assembly · 2025-2026 Regular Session

Public transit: California Transit Stop Registry: transit datasets.

Summary
Existing law establishes the Department of Transportation and vests it with various powers and duties. This bill would require the department to create, on or before June 1, 2027, and with input from transit operators, the California Transit Stop Registry as a centralized, statewide dataset of standardized information regarding transit stops that includes, but is not limited to, each transit stop's name, location, available seating, and unique identifier, and information on whether the transit stop is sheltered, as specified. Existing law provides for the funding of public transit, including under the Mills-Alquist-Deddeh Act, also known as the Transportation Development Act. This bill would require a transit operator, as defined, on or before January 1, 2028, to (1) ensure that the name and location of each of its transit stops conforms with the name and location for the stop in the California Transit Stop Registry, (2) use a transit stop's unique identifier listed in the registry when publishing any dataset with stop information or during publication of agency open datasets, and (3) report, for inclusion in the California Transit Stop Registry, if each of its transit stops has seating and shelter. By requiring a transit operator to perform new duties, the bill would impose a state-mandated local program. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that, if the Commission on State Mandates determines that the bill contains costs mandated by the state, reimbursement for those costs shall be made pursuant to the statutory provisions noted above.
