In a transport area of more than 5,000 square kilometres the Central Saxony Transport Group VMS (Verkehrsverbund Mittelsachsen) guarantees seamless connections as well as a uniform fare zone for three administrative districts and the city of Chemnitz. In total, the 17 transport operators involved have around 80 million passengers annually.

VMS decided to introduce a multi-tenant operation control system in order to bring all transport operators up to uniform technical standard, and to improve the service for the passengers in the association region. The association had a particular focus on automatic connection assurance across the different operators as well as standardised real-time information in the transport association.

The VMS decided on the IVU.suite’s integrated products. The basis for this is the multi-tenant operation control system IVU.fleet together with the on-board computer, which IVU will install in around 1,000 buses by the middle of 2021. In addition, IVU will install the in 100 trams. While IVU.fleet as a complete ITCS continuously monitors all of a trip’s aspects and automatically warns the dispatchers in the transport operators’ control centres, if there are irregularities on a route, the driver-operated on-board computer records the vehicle’s position and transfers it to the control centre via mobile communication.

The integrated IVU system creates a consistent database for uniform standardised processes. This makes it possible for VMS to offer their passengers continuous real-time information. In the future, the automatic connection assurance will inform drivers and dispatchers if the previous trip is behind schedule. The waiting bus then delays its departure from the stop for longer, so that the passengers can reach their connection – this is an important service improvement for the passengers in the evening and in more rural regions.
