Traffic tolls cut 65,000 trips a day in London

A year ago the city of London in the U.K. established a virtual toll barrier around the central city, charging about $12.50 to vehicles entering a 21-square kilometre zone.
The scheme was intended to cut down on heavy traffic congestion by discouraging drivers from coming into the city during weekdays. Cities like Toronto were considering imposing a similar scheme.
After a year, the results are showing that the London toll has managed to cut down on traffic significantly: reducing traffic trips by about 65,000 every day.
However, the revenue is below its projections. Tolls have brought in around $300 million, but that is only half of what was projected. Apparently the problem is that many people are refusing to pay the toll and the $100 fine.
