Ubiquitous platform for vehicles of passengers' public transport

In this article we describe a ubiquitous system developed and implanted in a public transport company. The system provides services to different actors inside and outside the vehicle as: drivers, operation maintenance and staff and travellers control. The main benefit of the system is that it solves the traditional problems of current systems installed on vehicles of road transport companies, providing the typical features, and also makes possible to develop new ones. This article describes the main features of the system: objectives, overall structure and operating principles and, finally, two examples of ubiquitous applications that run on it.
