Real-time data: reliable information from DDIP

If there are multiple recipients for a real-time data flow, MENTZ DDIP handles multiplexing. In such a case, the platform makes all required subscriptions available to all recipients, and no additional subscriptions are necessary on the supplier’s side.

In this context, the reverse channel back to the data supplier is a challenge, especially for connection monitoring services. To solve this problem, the references and IDs are intelligently managed in DDIP.

If the data subscriber needs the data in another format or service than that provided by the supplier, MENTZ DDIP can build a bridge. All VDV, SIRI, and GTFS formats can be converted into each other by DDIP. Moreover, DDIP can map data from one service to another wherever it makes sense.

Example of a format conversion:

SIRI ET/PT into VDV 454 AUS/REF-AUS

Example of a service conversion:
SIRI ET/PT into VDV 453 DFI/REF-DFI

If there are delays or cancellations in public transportation, schedule connections can often no longer be made. Passengers must take later connections or move to a different route. In such a case, it is not enough to dispense real-time information merely as a qualifier for route results based on the regular timetable. MENTZ’s electronic schedule information therefore integrates real-time data into routing from the very beginning. This guarantees that helpful connection information will reach the passenger even if there is a disruption.

In big cities, millions of commuters count on public transport every day. Accordingly, they must have access to reliable information.

That is why DDIP and the EFA electronic schedule information system are entirely HA-capable (High Availability). They can be set up and operated in clusters so that operation continues without interruption even if individual hardware and/or network components fail.
