Greater London Bus Passenger Survey (GLBPS)

<< Go Back

We have been continuously responsible for GLBPS since inception in October 1990. The GLBPS is an extensive on-going study of the travel patterns on London’s buses which aims to accurately record the amount of concessionary travel on the London bus network and establish a fair basis for the allocation of off-bus revenue (Travelcard etc) between the many different bus operators. The survey findings form the core basis for off-bus revenue apportionment, both amongst operators and the London Boroughs. The key objectives of the survey are to measure: passenger mileage travelled by ticket type (grouped as required) for a single route or set of routes undertaken by a single operator; and, at a network level, by ticket type the volume of journeys, average length of those journeys and equivalent cash fare payable for those journeys. As the variables measured are inter-correlated the analysis involves complex bias correction procedures.
