The BRT station platform doors separate the platform waiting area from the vehicle movement area to ensure the safety and comfort of passengers waiting for trains. The BRT platform doors have a good monitoring system, which is responsible for controlling the opening and closing of the platform doors, ensuring that the opening and closing of the half-height safety doors are consistent with the opening and closing of the vehicle doors; realizing the monitoring of all the operating states of the platform doors and the alarm of faults to further ensure the safety of passengers getting on and off the train.
