Congestion inside the zone fell about 30% in the first year and the scheme returned a surplus for transport. By 2007 TfL's own monitoring found congestion back at pre-charging levels.
what does this mean?
The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went.

Since 17 February 2003, drivers entering central London during charging hours pay a daily fee, enforced by ANPR camera rings — a scheme introduced under Mayor Ken Livingstone. The charge rose from £15 to £18 in January 2026, with EV exemptions replaced by a smaller Cleaner Vehicle Discount.
📊 Impact
In year one (from Feb 2003), congestion in the zone fell about 30%, traffic entering the zone fell 18% (65,000–70,000 fewer daily car trips), average speeds rose from around 14 to around 17 km/h, and TfL's audited accounts recorded net revenue of £45.3m from congestion charging for 2003/04. By 2008 TfL's own monitoring found the traffic reduction had held while the decongestion benefits had been progressively eroded — which it blamed on interventions that removed road capacity, not on the level of the charge. Its 2008 report put average congestion in 2007 at the same level as before charging, even though traffic in the zone stayed lower.

but the gains did not hold, and the operator's own monitoring puts that down to road space taken away elsewhere rather than to the price being wrong.

The report the erosion sentence describes, and the one that names a cause: the traffic reduction held while "the decongestion benefits seen in 2003 have been progressively eroded" by "a range of interventions and incidents that have removed effective capacity from the central London road network"; average congestion in 2007 "was identical to representative pre charging values", and the 2005 rise from £5 to £8 showed no visible break in the congestion series.

What the price is actually attached to
Every scheme here charges for driving, and each attaches the charge to a different thing: a road segment, an area, a single lane, or a digit on the number plate. What the price is bolted to decides what it can and cannot do.

|---|---|---|---|---|---|---|---|
| Electronic Road Pricing (ERP) NetworkSingapore, 🇸🇬 | 1998 | Live | Succeeded | Independent | Utility or public operator | not public | A road segment, priced to hold a speed band — the rate moves until the traffic does. |
