Nooooo! That would just increase the length of the traffic queue, while the pedestrians get a separate phase and the red lights are even longer.

Yes, this is part of the problem. Those seeking alternative routes, and finding Manor Mount denied them (let's assume, just for a moment, that some motorists aren't going to go the wrong way), rat run down the other "connecting" roads to Devonshire Road, as people like Roz have found to their cost.

What happens if your journey is not local? You get even more hacked off as you have the rest of the south circular (grrr....) to deal with once you've got past the lights. Besides I still take the car to Sainsbury's as I can't carry all the shopping up the hill.
