London congestion charge
In London, drivers are charged for driving in the congestion charge zone. The aim is to discourage drivers from using the zone during peak hours.
By using public transport instead, this reduces congestion, time spent in queues, the pollution generated and the cost to the economy.
The money generated is used to improve public transport, e.g. London buses have been renewed and the older vehicles, which generate more pollution, have been removed from service.
The results:
- traffic congestion, accidents, and pollution levels have all been reduced
- bus services are more reliable
- retail sales inside the congestion charging zone have increased
- there has been increased investment in public transport
There are limitations however, as many people still simply pay the congestion charge and keep on driving, which means more congestion.
