Abstract
A method for calculating a location interval of a railway vehicle, including: calculating, at predefined and successive times: maximum and minimum positions reached by the vehicle as points on a digital map based on signals indicative of the absolute position of the vehicle; maximum and minimum distances travelled by the vehicle with respect to a reference point based on odometry; at a selected time adding: to the maximum and minimum positions at a time earlier than the selected time, the difference between values of the maximum distance at the selected and at the earlier times and the difference between values of the minimum distance at the selected and at the earlier times, thereby determining reference first maximum position and second minimum position. The advanced end of the interval is the most forward position between the first reference maximum position and the value of the maximum position at the selected time.
