An empty-vehicle trial in a quiet period may not represent peak-day loading and receipt. Artificial extremes can mislead too.

Selection file

  • Route class
  • Selection reason
  • Actual load
  • Test-day difference

Set the method first

Assess similarity in duration, stop pattern, load, staff and ambient exposure together; document the rationale.

Review trial trips

Classify routes by duration, stops, fill, door handling and delay history. Select a representative or boundary trip; disclose deviations.

Interpret covered profiles only; assess remaining routes separately.
