Underground travellers already facing above-average fare increases in the new year will also have to put up with huge hikes in Tube station car parking charges.
From January 5, weekday parking fees will rise an average 18.73% - going up from £4.27 to £5.07.
Saturday charges will rise from an average of £1.60 to £2.26, with Sunday tariffs increasing from an average of £1.12 to £1.66.
Transport for London (TfL) said the increases were the first for more than two years and would "bring the prices more into line with other local car parks".
TfL has around 11,000 car parking spaces at London Underground stations, with most in outer London boroughs. The 59 car parks are all managed through a contract by car park company NCP on behalf of TfL.
TfL said the new weekday figure compared with an average of £8.26 at other local car parks and that the Tube car parks were open all the time.
TfL commercial development director Graeme Craig said: "We have taken the decision to increase the tariffs at many of our car parks to bring them in line with local competitors.
"However, we have kept the changes to a minimum. Some stations will actually see a decrease or no changes to their current weekday or weekend tariffs."
