how long does a traffic light stay yellow?

Answer 1

Depending on the speed limit set for that zone. 35 mph usually bout 3 seconds. 55 mph usually bout 5 seconds. Average within city limits bout 3 seconds.

Answer 2

The timing cycle of each light color is determined by traffic engineers, usually using formulas that are already in existence for any given scenario. The duration of each light color varies based on location, time of day, speed limit, etc. Essentially, the above times are correct: 3-10 seconds. It should be noted that a yellow light can be 3-seconds at one time of day, and that same yellow light may be 7-seconds at another time of day.

Answer 3

About 5 seconds.

Answer 4

It depends on the traffic light. They usually decide this by the amount of traffic that goes thought the light. Some one's have censors that only change when a car is waiting, and others are timed depending on the traffic volume and the time of day.

Answer 5

5-10 seconds

Answer 6

Along arterial and collector streets that have several traffic signals spaced at periodic intervals, the traffic signals are synchronized to provide coordinated movement along the main street. The emphasis of this strategy is to minimize the amount of fuel consumed and air pollution produced. This is accomplished by setting the time relationships between adjacent signals and the amount of green time at each signal in such a way that the number of stops is minimized. Once the minimum stop solution is determined, green times at individual intersections are checked and adjusted as needed to minimize the amount of delay experienced by drivers given the constraints of the minimal stop solution

Answer 7

Usually anywhere from 3 to 7 seconds.

Answer 8

That's based on the speed limit. The higher the speed limit, the longer the yellow period.

Answer 9

10 seconds.

Answer 10

7 sec! 10!???
it duz depend on how bad da traffic is
