Greenwich Road Closers?

Getting around Greenwich is about to get even more nuts as almost all the roads around the park will be inaccessible for the large chunks of the day. Great news for me, who lives on one side of the park but my child's school is on the opposite 😅. From 27th they kick in, but these maps they've offered up are so confusing! There's green cameras and blue cameras, different coloured roads etc., nowhere does it say what the charge is if you get caught by the cameras etc. Also we've not gotten any thing about it in the post or anything. Anyone have any more information on this? Stressed.
