Transport for London has released detailed information on which parts of the UK’s road and transport networks will be most affected by the Olympics next summer.

TfL says problems will be apparent in certain locations at certain times, and that a blanket reduction in travel across London as a whole will not be required.

It has published hotspot maps which pinpoint where problems will be, and developed an online road journey planning tool which shows the additional journey time expected for journeys that need to happen at the busiest times and in the busiest locations, such as the delivery of perishable goods.

It says 70% of road traffic and two thirds of tube stations will be unaffected, but that businesses will still need to prepare. On the busiest days there will an additional three million journeys in London, meaning the road and public transport networks will be much busier than usual in certain locations.
