Maybe. There are really useful design features which could be employed to slow the traffic, give pedestrians a fair crack at crossing and still allow the buses and emergency vehicles to travel freely. The key to preventing safe crossing here is the speed of the traffic and at present and despite it being on a bend it is too high - except on the days when it is at a standstill and you can saunter across at will.
When the road was closed back in the summer and the traffic was re-routed along Westbourne Drive crossing along the South Circ. end was fine despite the traffic level because of the pedestrian refuge at the end of the road.
