METHOD AND CONTROLLER FOR DETERMINING THE RELATIONSHIP BETWEEN A TRACK-CIRCUIT TRANSMITTED CURRENT SIGNAL AND A RAILWAY VEHICLE LOCATION ON A RAILWAY TRACK Method for determining the relationship between a track-circuit current signal and a railway vehicle location, comprising - sending, by a track circuit, current signal across a railway track block, - measuring the current signal for different railway vehicles running successively on the railway track block; - aligning said measured current signals and calculating a reference curve (R) as the average value of all the aligned curves by using a Dynamic Time Warping algorithm, this reference curve (R) representing the relationship between the track-circuit current signal and the railway vehicle location on said railway track block. Figure 2 Algorithm]: DTW with Averaging for TC Reference Sequence Calculation input: alist with train move data sequences, 1, 1121 ... Stand number of algorithm iterations N. output: TC reference sequence , R=< r 1, r2, ... , rp> 1 begin 2 Initialize the TC reference sequence R 3 repeat 4 for i=1 to T do 5 Calculate DTW (I ,R) between the ith train move and reference sequence; 6 Find all elements of the ith train move sequence that are associated with appropriate elements of the reference sequence using DTW; 7 end 8 Update the elements of the reference sequence {rI}, Pas the average value of all associated elements of all train moves; 9 until Number of iterations reached OR no new DTW updates 10end
