London was recently faced with exactly that question: how to transport more people across the city efficiently without paying the astronomical sums required for either another Crossrail or an unthinkably damaging motorway.

The solution is in place now and is working. It’s the North-South and East-West Cycle Superhighways.

Any estimate of how many people these can move at peak volume? I'm curious how it compares to the Underground.
