Of course, traffic lights are an effective way of driving cars, this is what their popularity is determined. Most often they can be seen at intersections. But sometimes a passerby or a driver can see them at pedestrian crossings in those sections of the roads along which cars are most actively moving. There is a special mechanism for switching a traffic light. It allows you to understand at what point a certain light will turn on. If you master it in practice, then the moment of switching will be felt on an intuitive level.
Drivers often drive on their cars, and if the route is the same, then remembering the location of traffic lights is easy, but there are large intersections. If red light is on now, then it is difficult to determine the moment of the occurrence of green. To do this, look at other cars. Then the definition of the current indicator of the traffic light will not be difficult. To make it more clear, we give examples.
The first example of an adjustable intersection
Imagine the most common intersection. It has traffic lights for drivers and pedestrians. They can be seen in any city. For the simplicity of explanation, suppose that the four -lane road is wide, and the two -lane is narrow. Then the algorithm for switching traffic lights will be this:
First burns green light for pedestrians.
Next, the green light is turned on for cars of a narrow road.
After this, the readings of traffic lights switch to a wide road.
The cycle is repeated.
Suppose we have two drivers. The first rides along a four -lane road, and the second two -lane. At the moment, the first driver is located approximately 50 meters from the intersection. He looks at the narrow road along which cars are moving. If they move, then further the permitting readings of the traffic light will be his. If pedestrians go along the intersection, then first the green light for the second car will turn on, and only then for the first.
The second example of the passage of the adjustable intersection
In large cities there are intersections of a six -lane road with a two -lane. The latter will be called narrow. At such intersections, the algorithm for switching traffic lights and the drive rules are as follows:
First, the green light for pedestrians turns on.
Then cars go along a narrow road, it is also allowed to go drivers who want to turn right with the wide.
After that, for a wide road, it is allowed to turn in any direction.
Finally, you can go along a wide road.
How to guess the time of switching a traffic light?
It is important to navigate the movement of other road users also because of the poor visibility of the traffic light signals. This is especially true for bright sunny weather and old traffic lights. But poor visibility will not be an obstacle to you, if you understand the mechanism of functioning of the traffic light. How can one predict the time of further switching a traffic light? To do this, you need to look at the number of machines that have the right to move at the moment.
If at the moment there are few of them, then they started to go for a long time. The smaller the number of cars in the active strip, the greater the probability of signal switching. But you can not discount the loading of the road at the moment. Perhaps there are just a lot of cars. We plan our actions so that it is not necessary to stop. For example, you see a red color in front. Choose such a speed so that you do not need to slow down. Perhaps you drive up to the green traffic light only. There are a lot of cars around, and therefore it is better to slow down a little.
Not a single car will start to drive at the same second as soon as the traffic light gives permission to travel. The more cars, the longer you will have to wait. This rule is especially relevant with strong ice. Then the car at the beginning of the movement begins to tow, which provokes an even greater delay. The rules for traveling an adjustable intersection help to avoid accidents, so it is necessary to strictly observe them.
