Bus operator league tables
Our league tables show how our operators have been performing against a number of measures. There's also a network average for further comparisons.They are distributed internally, as well as to operators.
The reports give operators the data to measure performance against their own track record and that of other bus companies.
Data comes from electronic systems that hold bus mileage by day and route and also from our quality service indicator (QSI) results.
High frequency - excess waiting time
Routes with five or more buses scheduled every hour are called 'high frequency' routes. The table below shows how long passengers have to wait for a bus above the average scheduled waiting time. This is based on how performance varies from minimum standards.
High frequency - long gaps
This table shows the likelihood of waiting twice the scheduled interval between buses. This is based on how performance varies from minimum standards.
High frequency night buses - excess waiting time
The table below shows how long passengers have to wait for a bus above the average scheduled waiting time. This is based on how performance varies from minimum standards.
Low frequency - on time
Routes with up to four buses an hour are called 'low frequency'. This table shows the likelihood of a bus arriving on time, based on how performance varies from minimum standards.
Low frequency - early
This table shows the likelihood of a bus running early, based on how performance varies from minimum standards.
Night buses - on time
This table shows the likelihood of a night bus arriving on time.
Mileage before losses due to traffic delays
This table shows the amount of mileage operated against a schedule, before taking into account mileage lost due to traffic.
Actual mileage operated
This table shows the amount of mileage operated against a schedule, taking into account all losses.
Mileage lost due to traffic delays
This table shows the amount of mileage lost due to traffic.
