Tripandfuschia raises lots of points. Traffic growth in London is a fact of life and although TfL would like to contain it at present levels, it is unlikely to reduce. The opening of the ELL may well attract more cars to HOP and FH stations as the train becomes an alternative commute route to driving or buses for many people so parking pressures may get worse. It's not clear where the rat running traffic would go if not down Devonshire Road. Any suggestions? Ideally it would not travel too fast and would not be held up at the junctions - unfortunately the clearer the junctions the more traffic is likely to be attracted to the route. Pavements should, of course, be clear for pedestrians. However, forgetting commuter parking, if the residents of Devonshire Road were all to park on the road, the road would probably be impassable to two way traffic and the amount of damage to vehicles would increase. In one of my local roads years ago, the residents all agreed to park on the road to make a point about rat running traffic. The Police threatened the parking drivers with obstruction when the inevitable gridlock occurred! The solution was to legitimise pavement parking within marked boxes and to ticket drivers who parked outside the boxes. This kept a reasonable amount of pavement clear for pedestrians and allowed traffic to continue flowing. If the residents of Devonshire Road complain to the Council about pavement parking, this is probably what will happen - assuming the pavements are wide enough.

TfL are undertaking a major study on smoothing traffic flows on major roads (including the A205) and will probably be looking at the right turn onto the A205. My contact at the Council has said they may do some turning traffic counts later in the year if funds permit.
