Thanks for putting me onto this, really good discussion point.
This is a good video to watch a busy junction without traffic lights in action in India, not necessarily a model to base anything on, but proof it does work.
I notice Ben Hamillton-Bailie is one of the interviewees in the newsnight programme, he's done a very short and simple introduction to the concept of shared space which can be found here.

I'd like to point out my main motivation for being car free is motorists ridiculous attitude that they have special privileges for use of public space in towns and cities. The 'I'm bigger and faster than you, get out of my way' attitude, that even on this discussion forum seems to prevail for motorists.
At present the majority of our public space in cities is road space, which is fine, as long as pedestrians have absolute priority on all but the major arterials, basically the whole road network should be treated as a zebra crossing. Motorised traffic must slow down or stop for Cyclists, who in turn must slow down, or stop for pedestrians. Basically pedestrians and cyclists must have legal priority over motorists.
Bus lanes should of course be considered as different beasts, and given priority unless they go through pedestrian priority zones.
One point to note which Ben HB mentions in his article, is that no matter the road design, paving etc, if pedestrians are perceived as rare then cars speed up and come to dominate the space.
With kids being forced to stay indoors due to parked cars and road danger, pollution, noise and congestion growing problems, we need to take back our cities for people, and maybe pilot schemes removing all distinctions between pavements and roads and planting trees, with outdoor cafes placed in the middle of the road might be the beginning.
We need to stop worrying about traffic flows and start building places where you want to stop and enjoy being.
And hell, about time we shook those 'stop at red' cyclists awake to the real world, slow down, check for space and carry on guys. Maybe one day we can allow motorists this privilege too, but not yet, they need to be driving 50cc engined electric cars restricted to 10mph in cities first. I don't think people can be trusted with anything more powerful.
