The ITCS of KÖR coordinates all the busses, trams and underground trains using a computercontrolled traffic management system. It controls the voice and data communication between dispatch centers and vehicles. For this purpose, the ITCS also integrates status and location data of the vehicles from AVLS and GIS applications.

KÖR handles one of the largest and most frequently used local public transport networks in Germany. 

A smooth operation and intelligent integration of the ITCS impose high demands on the mobile radio network: It must be able to integrate a multitude of users as well as quickly process enormous quantities of information and formats. At the same time, it must be robust, interference-resistant, safe against manipulations and expandable.

For this reason, there was hardly a way for KÖR to get around our ACCESSNET-T mobile radio solution. It is nearly endlessly scalable and covers all the network units from the control centre down to the individual radio transceiver. It fits perfectly into the existing system technology, ensures maximum security in the voice and data communication, optimizes the data management and also integrates non-system components.

After a detailed inventory and demand analysis, we implemented an individual ACCESSNET-T network according to the TETRA standard for KÖR. The core of the system is formed by two central switching nodes. They work redundantly, i.e. if one fails, the other automatically takes over its functions to prevent breakdowns.

Together, both switching nodes check a total of 28 base stations in indoor and outdoor operation. As requested by KÖR, each station features two or three TETRA carriers, giving the entire network over 60. We coupled the ITCS to the control centers, which are independent of each other, of the three KÖR transport operators. Each includes ten AVLS and GIS-compatible dispatcher workstations.
