Pedestrian crossing light not working

The pedestrian crossing light in the middle island on Newport road at this complex crossing is not functioning when trying to cross from the island to the north side of the road (i.e. across the carriageway moving eastwards down Newport Road. This means pedestrians are effectively marooned here unless they run across in the brief gap between green lights for the cars (not possible for everyone) or someone on the pavement on the north side of the road presses their pedestrian crossing button. I saw a woman in a wheelchair trapped by this issue for 3 cycles of lights last week, until I was able to activate the crossing from the North side so that we could all cross safely.

Also in general this crossing to get across the second half of the road isn't automatically triggered even if you press the crossing button on the south side of the dual road - no one will only want to cross to the middle island and stay there (as you are trapped) so it would make sense to trigger the whole crossing across both west and east travelling lanes at once. Otherwise more often than not pedestrians are trapped for at least one light cycle (when the middle crossing button is functioning) exposing them to unnecessary car fumes and pollution. It also means that people often risk running across the crossing during gaps between the cars but while the traffic light is still green increasing the risk of an accident.
