From TfL's Congestion Charge Impacts Monitoring Report, 2006, published three years after introduction of the charge zone.

*"The scheme generated net revenues of £122 million in 2005/6 (provisional
figures), partly reflecting the charge increases from July 2005. These are
being spent largely on improved bus services within London."*

**Bus reliability**

*As well as changes to the service provision and patronage of the central
London bus network in the period since 2002 there have also been significant
improvements to the reliability of bus services. These have reflected a variety
of factors, which have included increased investment in robust schedules,
enhanced route supervision and the introduction of Quality Incentive
Contracts, as well as the introduction of congestion charging that has reduced
congestion in and around the charging zone.*

*One measure of bus service reliability is ‘excess waiting time’, reflecting the
additional waiting time at bus stops experienced by passengers caused by
service irregularity or missing buses. In the first year after charging there were
improvements in bus service reliability for passengers in and around the
charging zone of around a 30 percent reduction in excess waiting time. This
was greater than the network wide average of around 20 percent for the same
period.*

*In the following year TfL recorded a further improvement of 18 percent
in the charging zone. This was similar to the network wide average for the
year of around 20 percent, as would be expected given that the ‘step’ change
represented by charging did not apply in 2004.*

*In the most recent year bus service reliability has been maintained, and with a
further fall in excess waiting time of 4 percent within the charging zone
compared to the same period the previous year. This comparative stability is
also reflected in the network wide change in 2005.*
