Matthew Phillip, chief executive of Notting Hill Carnival Ltd, said organisers would keep people safe.
“This year with some extra resources, we’ve vastly expanded. We’ve got a large crowd management team and resources around it, including extra cameras and information screens,” he said.
Some medics will get around on foot or bike, and it is factored into training. Peter Hollely-Robins, from St John Ambulance, said: “We do lots of simulation exercises to prepare and we work very closely with the police.”
Those using public transport to get to Carnival have been advised to check their route, with closures or changes affecting nearly all of the Tube stations in the area, as well as bus diversions being put in place.
Transport for London’s (TfL) Carl Eddleston said: “Some of the bigger stations like Paddington are about a 15 minute walk away and probably better places to go too, because they are obviously built and designed for big crowds.”
TfL has a dedicated website, external showing the best and quickest options for people to use.
