Since 1997, the Leipziger Verkehrsbetriebe (LVB) GmbH has been using the PERDIS system for personnel dispatch, and since 2006, the module DepotManagement for manual vehicle dispatch. In 2013, the bus depot Leipzig-Lindenau had to be downsized due to the expansion of an adjacent road. There were fears about an increase of shunting problems, wrong parking and time exposures for manual logging. In order to avoid this, the vehicle dispatch system was expanded.
In April 2013, initperdis won the tender and received the order to implement a visualised vehicle location system for the depot Leipzig-Lindenau. The contract included the expansion of the personnel and vehicle dispatch system MOBILE-PERDIS by a Depot Management System (DMS) with automated vehicle location. As the exact location of the vehicles down at the individual parking slot has been required (also in the interior hall area) and only a limited budget was available, they decided for a wireless location system. All buses were already equipped with transmitters of Agilion as part of the LVB project “Technisches Zentrum Heiterblick”.
The DMS view (TrackMap) for the dispatchers was designed by the customer and matches the actual site plan. The areas highlighted in blue are for “area localisation” where only the vehicle entry is detected and logically visualised. The dispatcher can see the vehicles that are in these areas. It is not necessary to know the exact location. This operating mode requires less hardware installation. Therefore the detection of exits became largely unnecessary. Vehicle exits are visualised once the vehicles are detected in a subsequent area. The two fueling lines and the washing bay are hidden from view.
This concept has been well accepted among LVB dispatchers right from the start. The interaction between software and localisation components is working very well. The DMS is designed to operate across all depots and can therefore be expanded to other LVB depots in the future.
Of course, LVB was convinced by the solution which has been integrated fully into the MOBILE-PERDIS system. They now have one system that fulfils all requirements of personnel and vehicle dispatch making many operational processes more efficient.
