Urban areas can be made more sustainable by encouraging:
London is attempting to be sustainable by encouraging the use of public transport. In an attempt to reduce traffic congestion London has adopted and/or improved several schemes
London underground - the extension of the Jubilee Line has encouraged more people to use public transport.
Oyster card - this is an integrated travel payment method which allows people to use buses, trains and tubes quickly and efficiently.
Congestion charging zone - this has discouraged people from driving their own vehicles in central London. A fee is charged to any vehicle travelling in central London between 7am and 6pm, Monday to Friday.
Bike-sharing scheme - bicycles can be self-hired in many public places in London for as little as £2 for short journeys. This has encouraged many people to cycle, reducing traffic congestion.
