Notice that this table excludes net revenue from the scheme, which was a little less than £80m in the first year. This surplus is earmarked for transport improvements. Effectively this gives a net annual benefit of £130m in the first year.
2006/7
The latest report by Transport for London states:
Traffic patterns remain broadly stable.
The July 2005 rise in price to £8 was effective in reducing traffic flow.
Congestion levels are on average 26% lower than before charging was introduced. Given that without charging congestion would have increased this represents an underestimate of the effect of the charge.
There appears to be no net impact on London’s economy.
Accidents and pollution have declined.
In 2005/6 there were net revenues of £122m.
Traffic Speeds
Traffic speeds have increased in the charging zone, but are falling again. This shows the ongoing problem of rising incomes and GDP will require more intervention in the future – see Singapore!
Commission for Integrated Transport
The CfIT has suggested a radical system that would lead to countrywide charging. Their aim is to manage the flow of traffic throughout the country, rather than in a few places. By using GPS they believe that it is possible to track and charge every vehicle.
They do not propose a rise in overall charges. Rather they suggest reducing fuel duty and vehicle excise tax and charging for use of roads when they are busiest. Thus someone driving on city centre roads at peak times pays a great deal, while someone driving along a country road pays little or nothing.
