The Passenger Load Survey (PLS) is undertaken to act as a snapshot of passenger loadings, network capacity and service utilisation. This survey is a physical head count, the PLS counts Queensland Rail passengers as they board or alight City Network services during both the AM and PM peak demand periods.
The PLS’s primary focus is peak flow services – services travelling towards Central Station in the AM peak and services travelling away from Central Station in the PM peak. These services represent the greater proportion of the travelling public.
Over the course of the PLS every ‘Peak’ and ‘Contra-Peak’ service within the peak periods are counted (refer to AM Peak and PM Peak definition). Counts are only undertaken on Tuesdays, Wednesdays and Thursdays of each week to capture maximum demand. Each service is counted once during the course of the survey by a team of load surveyors; one load surveyor is positioned on board each carriage of the train, counting passengers as they board and alight at each station as the train travels along its route.
The PLS data is currently being collected 6-monthly.
