description: Camera Captures and Confirmed Vehicles seen in the Congestion Charge Zone by Month Camera Captures and Confirmed Vehicles seen in the Congestion Charge Zone by Month during charging hours. Camera Captures since July 2010 and Confirmed Vehicles since October 2016. The count of captures is based on the unique Automatic Number Plate Recognition (ANPR) camera captures per day, which are added up to provide the total number for the month. This means that if the same ANPR camera VRM (Vehicle Registration Mark) interpretation is made more than once on a single day, it is only counted once; if it is made on multiple days during the month it is counted multiple times. The count of captures reflects the total number of unique VRM interpretations prior to validation and verification. The count of confirmed vehicles is based on unique confirmed vehicles per day, which are added up to provide the total number for the month. This means that if the same vehicle is seen more than once on a single day, it is only counted once; if it is seen on multiple days during the month it is counted multiple times. Drop from Jan 2011 for captures is due to removal of Western Extension. Monthly fluctuations are as a direct result of the number of Congestion Charging days each month and seasonal trends (i.e. school holidays).
