Scope
Queue Technologies treats waiting as a managed sequence of access conditions. The environment is evaluated through approach, recognition, entry, sequence, dwell, advancement and departure.
APPROACHENTRYDWELLADVANCEDEPARTURE
Method
MQT uses the PCP access envelope to test approach and return conditions. Meridian Ambient evaluates background continuity where recognition or dwell may be affected. Button & Interface reviews controls when a queue includes a human-initiated release, call or confirmation point.
| Condition | Review question |
|---|---|
| Approach | Can the expected entry direction be recognized without creating a second sequence? |
| Recognition | Is the next available position apparent under ordinary ambient conditions? |
| Dwell | Can a person remain in sequence without occupying another access envelope? |
| Advancement | Does movement preserve order and response certainty? |
