Real-time passenger information for deviations from normal operations

Control system, passenger information and transfer protection

In 2001, Stadtwerke Ulm Verkehr GmbH (SWU Verkehr) commissioned Trapeze to implement an operations control system.

The LIO system not only permits clearly improved realtime information for the passengers using various information media. It also enables SWU Verkehr to offer significantly more protected transfers than in the past.

To make more efficient use of the system, in 2009/2010 SWU Verkehr decided to equip all vehicles with modern IBISplus on-board computers by Trapeze, including 37 with the GPRS module.

Since 2010, SWU Verkehr has also been using Trapeze‘s Business Intelligence solution. This permits statistical evaluations and facilitates future planning.
