Congestion zone - increases in vehicles and delays
Request ID: FOI-1183-1819
Date published: 14 August 2018
In an article on changes to the congestion zone TFL wrote...
'We have found that average delays to journeys within the zone have been increasing. This is partly because there are an increasing number of vehicles entering the zone which are exempt from the charge or which receive a 100 per cent discount. Currently, only around 50 per cent of the vehicles entering the zone during charging hours are liable to pay the full amount.'
Are you able to provide figures per year that show the estimated number of vehicles entering the zone since it's introduction to date, the increase in average journey delays and the number of vehicles in the zone that receive the full discount?

Thank you for your request received on 26 July 2018.
Your request has been considered under the requirements of the Freedom of Information Act 2000 and our information access policy. I can confirm that we do hold the information you require.
estimated number of vehicles entering the zone since it's introduction to date
A monthly breakdown of vehicles captured driving in the Congestion Charge zone within charging hours is available online as part of the Mayor’s City Dashboard data on the GLA website; https://data.london.gov.uk/dataset/vehicles-entering-c-charge-zone-month
the increase in average journey delays
From June 2003, we completed operation impact monitoring and reported this annually on our website here: https://tfl.gov.uk/corporate/publications-and-reports/congestion-charge. The specific information you’ve requested can be found under the ‘Monitoring and research’ tab.
and the number of vehicles in the zone that receive the full discount?
Exempt vehicles are those which are not subject to the daily Congestion Charge i.e. buses, motorbikes. 100 per cent Congestion Charge discounted vehicles are those which first need to register with us to receive this discount. i.e. for the Blue Badge Discount and for Ultra Low Emission Discount. Full details can be found on our website here: https://tfl.gov.uk/modes/driving/congestion-charge/discounts-and-exemptions. The attached table depicts both the average unique vehicle volumes that are exempt and the average unique vehicle volumes that are registered with us to receive a 100 per cent discount.
Furthermore, our online fact sheets depict the exact amount of active Congestion Charging Discounts (not vehicles). These can be viewed here: https://tfl.gov.uk/corporate/publications-and-reports/congestion-charge
