Transport for London (TfL) is urging passengers to walk and cycle to try and ease the numbers returning to public transport as the second lockdown lifts today.
London is in tier 2 of the Government’s Covid-19 alert levels.
More customers are expected to return as London's shops, businesses and hospitality venues reopen and university students travel home ahead of the Christmas period.
The Government advice on travelling within tier 2 makes it clear that customers can travel to venues or amenities that are open, but they should walk or cycle where possible and avoid busy times and routes on public transport.
TfL is asking customers to plan ahead and travel during quieter periods.
These are currently between 08:15 and 16:00 and after 17:30 on weekdays, and before noon and after 18:00 on weekends on public transport.
On the roads the quiet times are between 10:00 and 15:00 and after 19:00 on weekdays, and before 10:00 and after 18:00 on weekends.
TfL has also published information about quiet stations and stops at tfl.gov.uk/quiet-times to help people travel through London during the quieter times and help maintain social distancing.
The list will be updated regularly as lockdown is lifted and parts of London become busier, particularly around shopping areas.
An enhanced cleaning regime on London's transport network will continue.
Trains and stations are cleaned with hospital-grade cleaning substances that kill viruses and bacteria on contact.
Recent independent testing, carried out by Imperial College London, has found - for the third month in a row - no trace of coronavirus on the Tube and bus network.
TfL has also recently installed more than 150 ultraviolet light sanitising devices on escalators on the London Underground network, following a six-week trial earlier this year.
Andy Byford, London's Transport Commissioner, said: “Londoners will be keen to enjoy London's shops, businesses and hospitality venues in the run up to Christmas.
“That's good for London, and we are here to get you where you need to go, but it's incredibly important that everyone follows the Government guidance on how to keep everyone safe and that customers continue to take the simple steps of good hand hygiene, social distancing wherever possible and wearing a face covering throughout journeys unless exempt.
“The minority of people who refuse to wear a face covering and who aren't exempt, risk being issued a fine from the police or our own enforcement officers.
“Parts of London may be busier, particularly around the popular shopping and hospitality destinations, so we are asking everyone to plan ahead and travel during the quiet times so that social distancing, and keeping safe, is easier for everyone.
“That way we can all play our part in keeping the virus at bay and helping London return to normality in the future.”
