Workshop 1

Created on Draw.io 

This is a mini diagram of how I think the process of outcomes will come with this set of traffic lights. To emphasize on this, this set of traffic lights shouldn't exist 😆😆. I don't find enough information from the original image. you have a set of 4 traffic lights facing the same direction indicating to me it's 2 for East and West and neither North and South. One direction of the conjunction is mainstream traffic meaning one road is due heavier traffic and therefore gets more attention and time of signals.

Created at draw.io

Every minute or 2 without pedestrian interference light signals have to change to balance the traffic from all directions. 

This is the second diagram explaining more about the introduction of Pedestrians. If and at every light, Pedestrians should get attention first. When and if any light trigger is pressed at any light, normally there is a delay of 30 seconds  for when signals change but with pedestrians once pressed get to cross. I don't get the full aspect of this set of lights because there isn't a full picture. They are sustainable lights but be a better situation. 

Overall I believe there should be 4 sets of 2 lights at every stop including turns. Realistically I haven't seen a formation of lights that badly thought out. Maybe I'm not seeing the big picture or something else. Unless they are zebra crossings therefore all and any pedestrians get full access to cross the road and set a lower speed limit for all four roads so no problems are accidents are caused,
