I think Ivonne is on the right track here. I was thinking that all we're doing is looking at certain bridges in one direction. Nothing is being considered about traffic flows coming into the area or across the area.

The interesting point is that the LRR and PBR have large build ups of traffic but, as I understand it, the north bound Putney Bridge is usually free flowing? That implies the bridge isn't the constraint but that traffic is either being throttled entering the bridge, either by constricting the entrance to it or by traffic crossing between LRR and PBR in both directions causing "turbulence" for traffic from LRR, PBR & PHS northbound trying to enter the bridge thus slowing its entry, or possibly both.

Keep in mind, depending on their final destination, some people might go further than the bridges in Richard's chart: Vauxhall, Lambeth, Waterloo, Blackfriars, Southwark, ...

To do a proper, rigorous analysis one needs to know the details of traffic flows in, out and at sufficient points across the area ... (to me, it seems similar to a fluid dynamics problem) but the only conclusion is there's too many cars for the available road space!

It's probable that other changes in or around the area - banning turns, shutting off rat runs, further parking & stopping restrictions. etc might affect traffic flows ...

One would have thought the consultants TfL use to model traffic flows should be able to gain insight into this? (But if it's analogous to fluid dynamics that might mean trying to solve some complex, difficult partial differential equations!)
