consider it like a stop sign, person to the right goes first...if you come to it at the same time.
traffic direction and control a planned assignment that may take place regularly at schools before and after closing.

No one really controlls the traffic lights. A computer system controls the traffic lights, and no humans are involved with controlling the traffic lights day in and day out. It is all automated these days.
The new traffic lights are now LED lights and do not ever burn out.

Pedestrians have priority over everyone. Emergency vehicles displaying flashing blue lights have priority over all other vehicles, however vehicles should only let them pass if it is safe and legal to do so. For example, you should not run a red light in order to let a vehicle with blue lights pass you as this is illegal and may not be safe. Vehicles displaying green flashing lights do not have priority but it is common courtesy to let them out or let them pass if you can do so safely and legally. Be aware that green light vehicles are not exempt from road laws and therefore cannot speed or run red lights, etc. At junctions, the vehicles on the road that you are joining have priority over you. On roundabouts, vehicles approaching from the right and also vehicles already on the roundabout have priority over you. On motorway and dual carriageway slip roads, you must give priority to the traffic already on the road. When merging, the lane that you are merging into has priority although 'merging in turn' is common courtesy and usually indicated by signage. When turning right, oncoming traffic has priority. Buses, taxis, motorcycles and bicycles are given priority lanes in larger towns and cities. At level crossings, trains have priority.
Traffic lights are made of part metal and part glass.
people can be colorblind. When the power goes out so do the traffic lights.
Logically, unless there were reasons to control traffic, there would have been no reason to create or install traffic lights. Because "traffic" generally comprises vehicles (motorized or otherwise), the traffic was probably there prior to the lights. Certainly, there were mechanical traffic signals that preceded traffic lights, not to mention traffic officers who once stood at busy intersections to direct traffic on a regular basis.
Follow the road laws of the country that you are in. In some countries the traffic already in the circle has priority. In others, traffic entering the circle has priority. Very clearly a recipe for disaster if you forget which country with which rules you are in!
