Navigating Bow roundabout/flyover

Road diets eh? It's a concept I totally love, but it's really counterintuitive so it's difficult for planners to believe that it will actually work and it's really hard to sell politically.

That, too, but it's important to realise that sometimes reducing the number of traffic lanes can actually increase motor traffic throughput. In the particular case of the A118, and other urban motorways, like the A102 and A12, the idea is to reduce awkward lane-changing movements at the signalised junctions, as it actually reduces motor traffic capacity more than reducing the number of traffic lanes would. The latter would confuse people less about what kind of lane to take. It's obviously different for motorways without any form of signal-controlled junctions.
