Simplified dispatching and transfer protection

Parity system, transfer protection, multi-functional displays

The LIO control system has given BERNMOBIL an efficient, state-of-the-art Automatic Vehicle Location and Control System (AVLC). The project was implemented in three stages starting in 1999, so that the transport service provider was in a position to use a large number of the system‘s features as early as possible. Bus operations run by Regionalverkehr Bern-Solothurn (RBS) and Postautos in the Bern Region are also connected up to the system.


The functionalities

  • Automatic vehicle location and control system type LIO
  • Analogue radio system and GSM/GPRS
  • Modern on-board computers 
  • Logical positioning with infrared beacons (urban), GPS-based positioning (region)
  • Real time passenger information: SmartInfo stop signs, MFD G2 multifunctional displays
  • Timetable information via the Internet
  • Advanced data management
  • Data supply LIO-Data
  • Traffic light preemption
  • Software and data loaded to the vehicles using wireless LAN (WLAN)
  • Statistics evaluation 
  • Transfer protection

Bernmobil carries 90 million passengers every year with 165 buses and 48 trams. In the Swiss capital, the transport service provider serves more than 200 bus and tram stops on more than 20 routes in the greater Bern area. Bernmobil has a workforce of round 720 employees.

“Introduction of the parity system has clearly simplified the work of the dispatcher in mixed radio traffic. We are also satisfied with the way the new transfer protection G2 has been implemented. It illustrates the great expertise that Trapeze has acquired in this field.”
