The new modeling shows that London is just two to three days behind the coronavirus hotspots in the north-west and north-east.
Sources close to London Mayor Sadiq Khan say the city is under siege with areas under new control.
Data obtained a few days ago suggested that the capital was two weeks behind the northwest and northeast.
Mr Khan is urging ministers to close London at 10pm to cover the latest regional restrictions, including bars and restaurants.
Those who are able to work from home are also reported to see the possibility of asking to do so.
A mayoral source said: “It is clear that lawsuits in London are moving in one direction only. We are now just a few days behind the hotspots in the North West and the North East. We cannot delay any further.
“The new measures will help reduce the spread of the virus and prevent the need for the full lockdown we saw in March, which could once again cause serious damage to the economy.”
Several areas in the Northwest and Northeast are subject to strict lockdown restrictions after acute infections.
On Friday, the mayor said there was a “growing possibility” that tougher restrictions would soon be needed to reduce the spread of the virus in London.
Coronavirus Cases are on the rise in many London cities, although they have not yet been placed on the government’s watch list as areas of concern.
About 2,289 new cases were confirmed in the capital during the week to September 11, compared to 1,822 in the previous week.
Redbridge has the highest case rate, with 39.2 cases per 100,000 people, Hounslow at 37.3 and Enfield at 30.6.
Generally, when the infection reaches above 100,000, the government takes strict measures and enforces strict measures.
By comparison, the latest figures show that 546 new cases were recorded in Bolton from seven days to 14 September – the equivalent of 189.9 per 100,000 people.
Mr Khan, however, indicated that he was keen to impose new restrictions as soon as possible to avoid a full lockdown.
“I am convinced that we should not wait as we did six months ago, before the virus goes out of control,” he said.

The mayor of London is also targeting the government, which he says has “catastrophically disappointed” the public during the epidemic.
In a speech at a labor-connected virtual assembly on Sunday, he said: “We are now working for a second wave – but still without effective testing, track and isolation measures – which makes a further lockdown even more likely.
“It’s not an accident or a coincidence. It’s not a geographical or climatic phenomenon. It’s because of the complete incompetence of our government.”
