Odometric estimation for Automatic Train Protection and Control System

The paper summarizes the main steps necessary for the definition of the odometry algorithm that can be used in the Automatic Train Protection and Control Systems. In this kind of devices the availability of a reliable speed and travelled distance estimation is essential for the efficiency and the safety of the whole system. The first step is the analysis and the choice of the sensors that can be used for the odometric estimation, a procedure that fuses the measures obtained from the sensor is defined. In the paper the main features of the developed solution will be summarized and its performance, in terms of precision in the speed and travelled distance estimation will be presented.
