REQ-picture-freshness | Every displayed state value is at most three seconds old; older values are marked as stale. | ✓ |

REQ-waiting-time-promise | The waiting time shown to the passenger is met in at least 95 percent of cases in normal operation; deviations of more than 60 seconds are actively reported. | ✓ |
