Most Londoners reckon congestion is going to worsen in their city over the next five years.
As many as 40% of the 1,055 adults polled said congestion would increase a lot, while 38% believed it would increase a little.
The most popular solution, but with only 29% support, was for a higher congestion charge during the rush hour.
Respondents were split down the middle in terms of whether they should pay a toll to fund new bridges/tunnels in East London across the Thames to ease congestion, with 46% in favour and 43% against.
There were also strong objections to crossings near proposed bridges/tunnels that are currently free for motorists - such as the Blackwall Tunnel - also being subject to a toll to avoid potential delays caused by people switching to toll-free options close by, with 32% in favour and 54% against.
Transport for London has said the results of a survey into traffic speeds during the morning rush hour are "plain wrong". The survey by a GPS company found that vehicles travelled at just 0.08mph during the rush hour on Jamaica Road in Southwark.
