Are there any requirements for traffic light intervals?

The distance and interval of traffic lights at each intersection are different. Generally, the interval between national highways is 30 seconds, the interval between urban traffic arteries is 10 second, and there are two kinds of situations at fork roads: crowded side interval 15 second and crowded side interval 10 second.

Although the rotation of traffic lights has time regulations, each intersection is different, and each time period is different. Generally, it is set according to the traffic flow and people flow at each intersection.

It should be noted that in addition to watching the lights, vehicles generally have to look at the traffic police.
