Car trouble

Letters

In a recent letter to The Times, Ken Livingstone claimed that congestion in London had been reduced by 26%. This can only mean that, compared with the initial condition, London's roads are still 74% congested.

However, no indication is given as to what an acceptable level of congestion might be.

Could someone explain, simply, how 'congestion' is measured and what is the difference between 'congestion charging' and 'road use charging'?
