In answer to Michael's very good point about the gap between the two yellow junction boxes (which has now created a solid queue blocking the Barrowgate Road junction on both sides), the thinking must have been that if the junction box was continuous, then right turning traffic out of Barrowgate Road would block the northbound lane of SCR.I believe the key to understanding decisions made about the road layout in this area must always consider the impact on flows on the A4 which is the absolute top priority for TfL. I've never seen the northbound carriageway being blocked due to a log jam at the Barrowgate Road junction but that's not to say it doesn't happen. My guess is that it has been decided that formal enforcement at the junction will improve flows. This remains to be seen but anyone saying this is primarily motivated by revenue (even me when I alluded to this possibility earlier in this thread) is wrong. TfL would not allow changes this close to the A4 for any other reasons than improving flow.I still haven't been to have a look but there seems to be general agreement from those that have, that these changes are not working well and they might need to be suspended pronto.On a different point, we probably (me included) need to be a bit careful about using the term ratrunner in this context. Whether you choose the Sutton Court Road route or the Dukes Avenue/Barrowgate Road route to get to this junction you are travelling on primarily residential roads with similar carriageway widths. The main difference is that on the latter the houses are more expensive. Local people know to use that route if SCR is very congested and non-locals are probably directed that way by SatNav. There isn't really any cause to be judgemental.

That you are such a courteous and considerate driver does you much credit but you need to consider how your elevated standards of behaviour will operate at this junction which you evidently aren't familiar with.It is a relatively small number of vehicle lengths from the junction with the A4 and often many of them will be taken up by a bus. The light phase that allows people to cross the A4 is very short at the best of times and falls to just a few seconds if TfL want to accelerate movement on the A4.This results in tailbacks right up Sutton Court Road and it can take over 15 minutes to reach where the yellow box junction is located. When there are queues along Sutton Court Road, many drivers seek to avoid them by going down Dukes Avenue and then joining at Barrowgate Road.If you were to reach the front of this queue and adopted your 'after you sir' approach some of the many drivers queueing behind you might take issue with your generosity particularly as you are enabling ratrunning.My concern is that the yellow junction box will change the direction that ratrunning occurs at this point to the western end of Barrowgate Road. I still haven't had a chance to go and have a look properly but it seems to me possible that drivers emerging from Barrowgate Road to turn right onto the A4 will believe that, unlike a Keep Clear box, the yellow junction box does allow them to move onto the southbound carriageway of Sutton Court Road and stop. It seems to me that they would be justified in doing this as they wouldn't know when they exited Barrowgate Road if oncoming vehicles on the other side of Barrowgate Road would prevent them exiting the yellow junction box when turning right onto the A4. The council may have a different view but I think they may struggle to fine drivers turning right out of Barrowgate Road. The fact that there are two junction boxes suggest the council accepts that drivers turning right can move forward as long as they don't block the northbound lane of Sutton Court Road. This means that priority at this junction has all but been handed to traffic emerging out of the western end of Barrowgate Road something that will be quickly picked up on initially by professional drivers and then baked into apps like Waze.
