How long should an operator wait to be relieved?

The correct duration for an operator to wait to be relieved is two minutes. This allowance is based on practical considerations to ensure a smooth transition between bus operators. When an operator reaches the end of their shift, waiting this specified amount of time provides an opportunity for the incoming operator to arrive without causing significant delays in service.

With a wait time set at two minutes, it offers a reasonable balance; operators can maintain their schedules while accommodating any minor timing discrepancies that could naturally occur in transit operations. This practice also helps ensure the safety and efficiency of the service since operators are not hurriedly departing before their replacements arrive, potentially affecting the overall operation of the bus service.

Other options, such as waiting for one minute or a longer time like five or ten minutes, would either not provide enough time for a replacement to arrive, increasing the risk of delays, or unnecessarily prolong the break for the outgoing operator, which can also disrupt the service schedule. Maintaining the two-minute standard helps optimize the flow of service and keeps buses on their intended routes and timetables.
