Plzen chooses TaitNet Data System (TNDS)

The public transport authority in the city of Plzen, one of the Czech Republic's leading cities, has chosen to use the ground-breaking TNDS voice and data transmission solution from Tait Radio Communications as part of a major project to upgrade the communications and management of its vehicle fleet.  The whole upgrade project has been awarded to GES Electronics, a long-standing Tait system integrator based in Plzen.

Plzenske mestske dopravni podniky, a.s. (Pilsen Urban Transport Company), better known as PMDP, is responsible for all public transport in the city of Plzen, the main city in the west of the Czech Republic.  The city has a network of well over 300 vehicles, including trams, trolley buses and buses transporting more than 100 million passengers annually on 35 routes.

PMDP was managing communications across its network by means of Tait T2000 trunked mobile radios linked by means of a two-site  TaitNet T1530 network, owned, managed and supported by GES.

GES have now been awarded the contract to manage the complete upgrade, to include both on-board computers, to improve management of PMDP's vehicles and data capture, and the Tait TNDS voice and data system, to manage the flow of speech and data between the control centre and the vehicles.

The Tait system incorporates a two-site TN3100 MPT1327 system with TNDS functionality.  The system's capability encompasses:

  • Voice communications with all PMDP's vehicles
  • Polling of all vehicles every 10 seconds
  • Updating of passenger information on displays
  • Traffic light prioritisation
  • Collection of tachograph data

GES is also installing a new control centre for PMDP as part of the contract.

Commenting on the contract, Libor Valecek from GES Electronics said "This is an important contract for GES and we were pleased to be able to offer the innovative TNDS solution from Tait as part of the overall package for PMDP.  We have worked with Tait for many years and value the contribution that they have made to this project.   

Colin Eade, Business Development Manager for Public Transport Solutions at Tait added: "Following on from Dublin Bus selecting a TNDS solution, we were pleased that GES won the PMDP contract using a TNDS solution.  GES is a highly-valued Tait partner and we look forward to working with them both on this and subsequent projects."
