🚩 Why are red and green traffic lights important?
- Red and green lights have had to consider timing, namely: how long should one side of the intersection remain green, the other red. This creates the “capacity” of a signal: how many vehicles can move through on a single change of the light. This, in turn, creates (or disrupts) flow throughout the entire traffic grid of a city.

The lights for the cross traffic will then begin to change after a safe time period before the light turns green for you. Check for signs of loop detectors in the pavement just before the stop line and crosswalk markings.

These are often easy to spot because you can see the pattern of the wire on the road surface. How 'smart traffic lights' work
