I am writing this as a traffic signal engineer who works for BCC.

When waiting in the centre island to cross over Bond St to get to Brunswick Square it is impossible to see oncoming traffic due to the greenery growing in the central reservation. Chapter 6 of the Traffic Signs Manual refers to this as intervisibility and states '15.5.2. Pedestrians should be able to see and be seen by approaching traffic. Different groups will have different requirements – for example, wheelchair users and children may be harder for a driver to see as they are lower in the landscape.'

Chapter 6 also goes on and says that there should be at least 40m visibility when there is an 85th percentile speed of 30 mph. The speed limit here is 30mph, I am not sure what the 85th percentile speed is but the visibility distance should be 40m as a minimum. The coach is probably about 14m long and we're probably achieving a little more than that, maybe 18m to the back of the care? And this is if we're standing right at the display unit, if an adult with a pushchair or similar were standing there the intervisibility would be worse. The 85th percentile speed is probably higher so Chapter 6 says the distance of visibility should be closer to 51m or 80m.

One of the main issues is not just the shrubbery growing in the central reservation it is also the curve in the road. I've surveyed the rest of the greenery around the other approaches to pedestrian crossings in the area and either curve is in a different direction or there is no greenery on the approach so the intervisibility between pedestrians and drivers is ok. This is the only crossing that needs some attention.

COuld someone please look into this? I am happy to meet someone on site but my concern is that a lot of shrubbery needs to be removed if we are going to satisfy Chapter 6 of the Traffic Signs Manual.
