To achieve fail-safe protection, safe train separation shall be required automatic train protection (ATP) function for any communication-based train control (CBTC) system configuration, where the calculation of the ATP profile is a major function of safe train separation. In this paper, we present a feasible speed profile model for ATP system. First, a three-phase brake model is provided which includes system response and disabling propulsion phase, braking response, and braking build-up phase and fully braking phase to simplify the standard model. Second, a palette of speeds includes emergency brake intervention speed (EBIS), service brake intervention speed (SBIS), warning speed (WS), and recommended speed (RS) to meet various application purposes. Third, the evaluation shows that the speed profile model is feasible with practical engineering parameters.
