The examples shown are great positives for London, but one can't make a great city out of traffic modelling alone - even pedestrian (rather than vehicular) traffic modelling. Space Syntax take note...
As some one who works in central London it is not going to stop nutters on fix wheeled bikes riding at full pelt through clusters of pedestrians is it though?
Nope. To me, London has a separate problem with cyclists who think central London is a velodrome. Not to blame all cyclists, because most of them are fine - but there are some idiots out there with a complete disregard for safety..
