  3. 7. Development of new criteria for train detection and evaluation in critical conditions

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Sofiane Kerbal; [2019]
    Keywords : railway signaling; train detection; track circuit; shunt; frequency modulation; frequency-shift keying modulation; third-order harmonic; short-time Fourier transform; power spectral density estimation; cross-correlation;

    Abstract : Railway signaling is of paramount importance to ensure traffic management andsafety on the rail network. The main lines are divided into sections called ‘blocks’,which are governed by a fixed signal installation. To prevent trains from colliding,each block allows one train at once. READ MORE
