CA AB1599

Requires the California Department of Transportation to create the California Transit Stop Registry by December 31, 2026, as a centralized statewide database containing each transit stop's name, location, available amenities, and unique identifier

Mandates that transit operators receiving Transportation Development Act funding conform their transit stop names and locations to the Registry by June 1, 2027

Requires transit operators to use Registry-assigned unique identifiers when publishing any datasets containing stop information, including General Transit Feed Specification data, ridership datasets, and trip-planning application feeds

Provides for state reimbursement to local agencies if the Commission on State Mandates determines the requirements impose state-mandated costs
