For buyers contracting authority
Reach for 48813200 when the deliverable is live arrival prediction for public transport: the system that takes real-time vehicle positions and turns them into the times travellers see at a stop, on a screen, or in an app. That live element is the dividing line. A static estate of screens that only cycle scheduled times or service notices fits Electronic bulletin boards (48813100) better; the predictive, tracking-fed platform belongs here.
The parent question matters too. Passenger information system (48813000) is the broad bucket for traveller-facing information; reserve the child 48813200 for the real-time variant where vehicle tracking and arrival prediction are the point. Where a single procurement bundles the prediction platform with a wider intelligent-transport build covering ticketing, signalling or fleet management, set the primary CPV code by the dominant deliverable and split the strands into lots an authority can price independently.
Because these systems tie a transport authority to a platform, its on-street hardware, and a multi-year maintenance relationship, the specification should pin down data feeds, display standards and support terms early.
