The onboard speed control system of automated rapid transit vehicles receives a wide variety of legitimate commands from external sources. These commands occur at random intervals and include speed changes and commands to stop at a precise distance. These commands must be processed in such a manner that longitudinal acceleration and jerk of the vehicle are always within specified limits. One way to meet these requirements is to compute a command profile for each external command using a microprocessor. One of the tasks of UMTAS'S AIRTRANS Urban Technology Program (AUTP) with the Dallas/Fort Worth (D/FW) Airport and Vought Corporation was to develop a speed control system employing a microprocessor. The system has been installed in the AIRTRANS system and has been demonstrated at the D/FW Regional Airport. This paper describes the development of the AUTP speed control system.
