Carris carries approximately 385 million passengers annually across more than 100 routes with 2100 stops, using 815 buses and 60 trams, employing approximately 2000 drivers.

With a view to improving customer service, Carris decided to implement a system capable of optimising resources, providing a more regular service, providing information to passengers on waiting times, and improving staff and passenger security.

In order to meet these objectives, the system was required to provide continuous positioning information, connection to Police networks, immediate detection of abnormal situations, driving assistance, and bidirectional communication between driver and control centre.

The system chosen was XTraN Passenger, implemented over a TETRA network installed by Radiomóvel (a member of the consortium consisting of Tecmic, Radiomóvel and Efacec created for this tender). It is currently the only system operating over TETRA, a fact of which the consortium is very proud.

XTran Passenger is among the most advanced fleet management systems aimed at passenger transport in the world.
