SYSTEM COMPRISING AN ON-BOARD UNIT FOR TELEMATIC TRAFFIC SERVICES

A system comprising an on-board unit (OBU) for a telematic traffic service, for example an automatic toll collection service, and a software application which can be executed by an external user device, for example a smartphone, is described. The OBU comprises both a radiofrequency communication module for communicating with the road-side units (RSU) of the telematic traffic service and a proximity communications module (for example Bluetooth) for communicating with the external user device. The data processing unit of the OBU executes software applications which support the telematic traffic service and additional services. The software application executed by the external user device provides the user, via the user interface of the external user device and the proximity communications module of the OBU, with access to the telematic traffic service and to the additional services supported by the OBU.
