Typical diagrams of stations with arranged traffic lights. Typical diagrams of stations with arranged traffic lights How are traffic lights indicated?
Today it is very difficult to imagine traffic rules without the main tool for regulating traffic, which is a traffic light. It is designed to regulate and facilitate both vehicular and pedestrian traffic. There are different traffic lights depending on their functions. Although they are similar to each other, they have certain nuances that need to be remembered.
Traffic light: definition
A traffic light is an optical signaling device that is designed to regulate the movement of cars, bicycles and other vehicles, as well as pedestrians. It is used in all world countries without exception.
Interesting! Previously, there were no green lights in traffic lights in Japan. It was replaced by blue. But scientists have proven that green is more acceptable to human eyes.
Types of traffic lights
The most common are three-color traffic lights with round signals: red, yellow and green. Traffic regulations in some countries require the use of orange traffic lights instead of yellow ones. Signals can be located both vertically and horizontally. If other special traffic lights or additional sections are not provided, then they regulate the movement of all types of transport, as well as pedestrians. Next we will look at various types traffic lights, from everyday ones to special ones.
Classic three-section traffic light
Such a traffic light, as a rule, has three colors, arranged in order: red, yellow, green - from top to bottom or from left to right. Such traffic lights are installed at intersections. They are designed to allow simultaneous passage of all types of transport in all directions permitted by traffic regulations. They are also installed at controlled pedestrian crossings located between intersections. It is also possible to install such a traffic light at a railway crossing in populated areas, at the intersection of a road with tram tracks, in front of a bicycle path and a roadway. They can also be seen where the roadway is narrowed to allow oncoming traffic to pass alternately.
Interesting fact!The first three-section traffic light was installed in Detroit in 1920.
Two-piece
Traffic lights with two sections are used to regulate the flow of traffic in the territories of industrial enterprises and organizations, as well as during the narrowing of the roadway to organize a single-lane reverse traffic flow.
Single-section traffic light with yellow light
This one-color traffic light is found at unregulated intersections and pedestrian crossings.
Traffic lights with additional section
Traffic lights can also be equipped with additional sectional sections with arrows or arrow outlines. They regulate the movement of traffic in one direction or another. According to traffic regulations, such traffic lights operate as follows: the contours of the arrows on all signals of a conventional three-color traffic light mean that its action extends only in one indicated direction.
An additional section of a traffic light with a green arrow on a black background according to traffic rules allows passage, but does not provide advantages during passing. Sometimes you can find an always-on green signal, which is made in the form of a sign with a solid green arrow. This means, according to traffic rules, that turning is allowed, despite the prohibitory traffic lights.
Such traffic lights are installed in places where it is necessary to organize conflict-free traffic at intersections. If one of these traffic lights turns green, then when crossing the intersection you don’t have to give way. To avoid emergency situations, personal traffic lights are placed above each lane, which show the direction of movement that is allowed from a particular lane.
Reversible traffic lights
To regulate traffic along the roadway lanes, reversible traffic lights are used. These are special band control regulators. Such traffic lights can have from two to three signals: A red signal in the form of the letter “X” prohibits movement in a specific lane. A green arrow pointing down, on the contrary, allows movement. A yellow diagonal arrow signals that the lane mode has changed and shows in which direction you need to leave it.
Traffic lights for regulating traffic through a pedestrian crossing
Typically, such traffic lights have only two types of signals: the first one allows, the second one prohibits. As a rule, they correspond to green and red colors. The signals themselves can be of different shapes. They are often depicted as a stylized silhouette of a person: standing in red and walking in green. For example, in America, the prohibition signal is made in the form of a red raised palm, meaning “stop”. Sometimes the following inscriptions are used: red “stop” and green “walk”. In other countries, respectively, in other languages.
On highways with heavy traffic, traffic lights with automatic switching are installed. But there are cases when you can switch the traffic light by pressing a special button, which allows you to cross the road within a certain time. Modern traffic lights are equipped with a digital countdown display for convenience. For blind people, sound devices are installed in traffic lights.
To regulate the movement of trams
A traffic light for a tram is usually placed in front of areas with limited visibility, long ascents and descents, at a tram depot and in front of switches. Traffic lights for trams come in two types: green and red. They are installed either to the right of the tracks or hung centrally above the contact wire. Basically, such traffic lights notify tram drivers whether the path further is busy or not. They do not regulate the movement of other vehicles and are purely individual. Their work is built automatically.
Traffic signals: driving rules
The circular light signals mean the following: a static green signal allows the movement of vehicles or pedestrians, and a flashing green traffic light means that a prohibitory signal will soon come on, but for now movement is allowed.
Interesting fact!Residents big cities In general, they spend about six months of their lives waiting for the traffic light to clear.
What does a yellow traffic light mean? It warns that the prohibiting signal will be replaced by a permissive one or vice versa, and for the duration of its action it prohibits movement. A flashing yellow traffic light means that the section of the road on which the traffic light is located is not regulated. If it is located at an intersection and operates in this mode, then the intersection is unregulated. Drivers are guided by those articles of the traffic rules that stipulate the passage of unregulated intersections. A static and flashing red signal prohibits movement in any direction.
The red and yellow traffic lights that are on at the same time indicate that it is prohibited to move further, and the green light will soon turn on. The white-lunar traffic light signal informs that the alarm system is working and you can continue driving. Such traffic lights are installed on tram and railway tracks.
Traffic lights that look like arrows mean the following: red, yellow and green arrows mean the same thing as round signals, only they act in a certain direction. An arrow pointing to the left also allows a U-turn, unless the corresponding next priority traffic sign prohibits it.
The green arrow of the additional section has a similar meaning. If this signal is turned off or the red outline is on, it means that movement in this direction is prohibited. If the main green signal has a black outline arrow, then this means that there are other directions of movement than those indicated by the additional section.
What is more important: a sign, a traffic light or a marking?
Rules traffic imply the following priority: the main one is the traffic controller, then the traffic light, then the sign and then the markings. Traffic controller signals take precedence over traffic light signals and road sign requirements. They are mandatory. All traffic lights, except flashing yellow, are more significant than road signs. All road users are required to follow the instructions of the traffic controller, even if they contradict traffic lights, signs and markings.
In the capital of Germany there is a traffic light with thirteen signals. It is not so easy to understand his testimony right away.
Classic three-section traffic light.
Any of us knows from childhood that a red traffic light prohibits movement, and now both drivers are required to stop at the stop line.
But not everyone knows how a modern “advanced” traffic light works, what signals it may have and how exactly they alternate.
During the traffic police exam you will be asked:
What does the combination of red and yellow traffic lights mean?
The answer should not leave you in doubt - A brief combination of red and yellow signals informs drivers that the green signal will soon turn on.
The red and yellow lights go out, the green lights turn on, and you can move in all directions (unless, of course, signs or markings indicate otherwise).
But don't rush to start moving. The author of these lines has seen so many troubles and tragedies when neighbors along the road blindly followed the green signal. And this is not just advice, it is a requirement of the Rules.
Rules. Section 13. Clause 13.8. When the traffic light turns on, the driver is obliged to give way to vehicles completing their movement through the intersection, and to pedestrians who have not completed crossing the roadway in this direction.
That is, before you start moving, you need to make sure that those who have now turned red have stopped. Someone may simply not have time to stop, but someone is in such a hurry that they are ready to rush through the intersection risking their lives (okay, only their own, but also someone else’s).
Well, finally, the drivers on the road being crossed have stopped at their stop lines, and now they can start driving. We still see green light.
The green one burned, burned and blinked.
And again, during the traffic police exam, someone will definitely get this question:
What does a flashing green traffic light mean?
And again the answer is obvious - The flashing green light informs drivers that its time is expiring and the yellow light will soon turn on.
Is it possible to move when the green light is flashing? Don't doubt it, it's possible. Its duration is expiring, but it has not expired yet!
Another thing is that the green light will not blink for long - it will blink only three times and then go out.
Green will go out, but then yellow will light up. And this is what is said about the lonely yellow signal in the Rules, in paragraph 6.2:
« Yellow signal prohibits movement and warns about the upcoming change of signals.”
And this is where it is important for the driver to understand!– If the lone yellow light is on, then red will be next! That is, you will definitely have to stop!
Now imagine that the yellow light turns on when there are 5 - 10 meters left to the stop line. At a speed of 60 km/h, you can only hold the car by applying emergency braking! And even then, you will have to stop at the intersection (by crossing the stop line and risking getting hit from behind). Novice drivers often do this (sharply brake when the light turns yellow), and if an aggressive “experienced driver” was driving behind, then the novice is guaranteed to be hit from behind in this situation.
Meanwhile, the Rules prohibit sudden braking anywhere and everywhere (except for cases when it is necessary to prevent an accident):
Rules. Section 10. Clause 10.5. The driver is prohibited Brake sharply unless necessary to prevent a traffic accident.
That is, if the driver of a brown car suddenly brakes now, he will violate the requirement of paragraph 10.5 of the Rules. And in the event of an accident, both will be to blame - the driver of the red car is to blame because he did not maintain a safe distance, and the driver of the brown car is to blame because he braked unduly sharply.
The Rules treated this situation with understanding and allowed movement on a yellow traffic light (if it is no longer possible to stop smoothly in front of the stop line):
Rules. Section 6. Clause 6.14. Drivers who cannot stop when the yellow light turns on without resorting to emergency braking are allowed to continue driving.
And you may also be asked about this during the exam: “Are you allowed to continue driving if, when the traffic light turns yellow after the green light, you can only stop before the intersection by applying emergency braking?”
And here the answer should be absolutely clear to you - allowed. It’s simply allowed in any direction you want.
The lone yellow light will not burn for long - literally after a couple of seconds it will change to red, and the cycle will start all over again. But when the signal is red, drivers must definitely stop at the stop line.
And that's not all about traffic lights. If the traffic is not intense, then it is irrational to keep drivers at stop lines, and the traffic light can be switched to the so-called yellow flashing signal mode.
That is, red and green are not turned on at all, and only yellow is turned on all the time. Moreover, it does not just light up, but blinks at a frequency of once per second. This is how this signal is described in the Rules:
Rules. Section 6. Clause 6.2. Yellow flashing signal allows traffic and informs about the presence of an unregulated intersection or pedestrian crossing.
In this situation, drivers must independently determine the driving order, guided by general principle"interference on the right."
There is a problem in the traffic police book (shown below), which you often make mistakes when solving. Some of you for some reason choose the third answer. Most likely, because they did not read the question carefully. And the question says “when the traffic light is flashing yellow”! And, consequently, this intersection has become unregulated. And, therefore, we must be guided by priority signs.
Traffic lights with an additional section (or with two additional sections).
A classic three-section traffic light can be equipped with an additional section (right or left) or two additional sections (right and left).
This “rationalization” makes it possible to significantly increase the throughput of the intersection; it is only important that drivers correctly understand the signals of such a traffic light.
And, first of all, it is necessary to understand that movement in the direction of the arrow is only allowed when the additional section is turned on.
For example, traffic to the right is now open.
And only to the right and nowhere else!
Anyone who needs to go in other directions must stand and wait for the main green signal to turn on.
The main green signal is turned on, and note that there are black outline arrows on the main green signal.
This was not the case at a three-section traffic light, but for a traffic light with an additional section, the presence of contour arrows on the main green one is a must-have!
Now movement is allowed only in the directions indicated by the contour arrows.
But now traffic is open in all directions.
1. Straight or left. 2. Just straight ahead. What should he do if he needs to go to the right? 1. You'll have to go to the next intersection. 2. You need to stand at the stop line and wait for the right arrow to turn on. Comment on the task Now the traffic light allows you to turn left and make a U-turn. But only those in the left lane can do this. The driver of a brown car can only drive straight ahead at such traffic lights. |
Traffic lights designed to regulate traffic in certain directions.
Creative thought does not stand still, and traffic organizers were not satisfied with the fact that they proposed adding additional sections to the traditional traffic light. If necessary, you can provide a classic three-section traffic light with additional functions without equipping it with additional sections.
You approach an intersection and see instead of one traffic light there are three (according to the number of lanes in your direction).
It should be assumed that the effect of each traffic light extends only to the lane above which it hangs. And since the red signal is on everywhere, it means traffic from all lanes is prohibited.
Students. But why do red arrows light up instead of the usual round signal?
Teacher. This is done so that drivers approaching the intersection can change lanes in advance.
And the same arrows will light up on the yellow signal, informing drivers about the directions in which they will be allowed to move from this lane when the green signal turns on.
Now traffic is allowed from all lanes.
BUT!
It is necessary to adhere to the instructions dictated by the arrows on traffic lights.
Traffic light with a flashing yellow signal.
The most dangerous intersections in the driver's path are an uncontrolled pedestrian crossing and an uncontrolled intersection. At these intersections, drivers must independently determine the order of passage, guided by the relevant requirements of the Rules.
Traffic safety can be significantly improved if simple traffic lights with one yellow flashing signal are installed at such intersections. The continuous flashing of the yellow signal informs the driver in advance that he is approaching an unregulated intersection or pedestrian crossing.
There was no traffic light at this intersection. We hung it here with the help of graphic editor Photoshop.
But if he were actually here, this accident most likely would not have happened.
And these two-way traffic lights with a flashing yellow signal are not at all superfluous at an unregulated pedestrian crossing.
Reversible traffic lights.
Until recently, roads with reversible traffic were almost exotic in our country (although they have always been in the Rules).
And today you can often see such a warning.
And here it is - a section of the road with reverse traffic.
The roadway has appropriate markings (double broken lines with long strokes), and reversible traffic lights hang above the lanes designated for reversible traffic.
Now we have green arrows on at all traffic lights, and while they are on, these three lanes are given over to traffic in our direction.
On this section of the road, only one lane is allocated for reversible traffic. And now at the reverse traffic light we see a red cross. And, therefore, now the reversible lane is given to drivers in the opposite direction.
In our country, right-hand traffic is accepted and, in principle, everyone understands that when clearing the reverse lane, you need to change lanes to the right.
However, the Rules also provide for a three-section reversible traffic light - the yellow arrow, firstly, informs about the upcoming signal change, and, secondly, shows drivers where to change lanes, freeing up the reversible lane.
Now is the time for the driver of the blue jeep to turn on the right turn signals and immediately change lanes to the right. At the next reversible traffic light, a red cross will already be on.
Traffic lights for regulating traffic through railway crossings.
To regulate the movement of traffic through railway crossings, the Rules provide for three types of traffic lights.
This can be either one red light flashing once per second.
Or two alternately flashing red signals.
Or, along with two red signals, a white-lunar signal can also be installed, which, if turned on, also blinks at a frequency of once per second.
Now let's see what the Rules say about this:
Rules. Section 6. Clause 6.9. A round white-lunar flashing signal located at a railroad crossing allows vehicles to move through the crossing. When the flashing white-lunar and red signals are turned off, movement is permitted if there is no train (locomotive, handcar) approaching the crossing within sight.
That is, if one red signal is flashing or two red signals are flashing alternately, movement through the crossing is prohibited.
If the white-moon signal is flashing, movement through the crossing is permitted.
If nothing is flashing, movement through the crossing is also allowed. BUT! Not just allowed. First, the driver must make sure that there is no approaching train (within visibility!). And if there is one, then movement through the crossing is prohibited.
In conclusion, we note that GOST allows the use of conventional traffic lights at railway crossings.
Four-section traffic light with moon-white signals.
The use of such traffic lights makes it possible to organize conflict-free movement of route vehicles at intersections. We are talking about trams, as well as buses and trolleybuses, if they move along a lane specially allocated for them.
Now at the traffic light all four white-lunar signals are on and, therefore, the tram (bus, trolleybus) can move in all directions.
If the bottom signal and the top left signal are on, the tram (bus, trolleybus) is allowed to move to the left.
If the lower signal and the middle upper signal are on, the tram (bus, trolleybus) is allowed to move straight.
If the bottom signal and the top right signal are on, the tram (bus, trolleybus) is allowed to move to the right.
If the bottom signal is not on, then the tram (bus, trolleybus) is turned on “brick” - entry into the intersection is prohibited.
Now the tram is allowed to go straight or to the left, and we are allowed to go straight or to the right.
Indeed, a conflict-free movement.
Now the tram is allowed to go straight or to the right, and we will stand at the stop line.
And again, no conflict.
But now the tram will be stationary, but we can go in all directions.
And again, no conflict.

Today, every person understands what a traffic light is. The colors: red, yellow and green are familiar even to a child.
However, there was a time when these optical devices did not exist, and crossing the street was not very easy. Especially in big cities, passers-by had to pass endless horse-drawn carriages for a long time.
On the cross streets there was confusion and endless disputes.
A short excursion into history
The traffic light was originally invented by the British. It was staged in London at the end of 68 of the 19th century. It was controlled by a man. The mechanism had two hands. When they were in a horizontal position, movement was prohibited, and when they were lowered, passage was allowed. At night they turned on a gas burner, which gave a red and green signal. It turned out to be unsafe. The gas exploded, injured a policeman, and the traffic light was removed.
It was only at the beginning of the twentieth century that an automatic traffic light was patented in America. Colors were not used in it; inscriptions replaced them.
The red color is very visible in any weather: when the sun is shining brightly, it is raining, or there is fog. From a physical point of view, red has the longest wavelength. This is probably why it was chosen as forbidden. The meaning of red is the same all over the world.
The other signal at the traffic light is green. This is the color of calm and tranquility. It has a relaxing effect on the human brain. Green allows movement. It can be seen far enough away; any driver sees this color long before passing the traffic light and calmly, without braking, crosses the intersection.
However, as they say, there is an unspoken rule according to which it is still worth slowing down when driving through a dangerous intersection, even when the traffic light shows green. This action often helps avoid serious accidents.
Yellow - pay attention
Yellow traffic light color is intermediate. It carries a warning function and calls on traffic participants to pay attention. The color yellow is said to symbolize intelligence, intuition and intelligence. It usually lights up after red, calling on drivers to get ready to move. As practice shows, many drivers perceive a yellow traffic light as permission and start moving. This is wrong, although it is not punishable by penalties. When the yellow light comes on, you need to depress the clutch and get ready, but to start driving it is better to wait for the green light, especially since the wait is only a couple of seconds.
In reverse order: green, yellow, red - the traffic light does not work. In modern devices, after green, red immediately lights up, while in the last minutes green begins to blink.
You can also sometimes see a continuously flashing yellow traffic light. This indicates that the traffic light is disabled or broken. Most often, traffic lights flash yellow at night.
Pedestrian traffic light
There is also a traffic light to regulate pedestrian traffic. What colors does it use? Red and green - definitely, but yellow is absent as unnecessary. A person does not need any special preparation to cross the road.
They are usually depicted as walking men. For the convenience of pedestrians lately a time counter is used. A special stopwatch counts down how many seconds are left before the opposite signal turns on.
As with regular traffic lights, red prohibits traffic, and green indicates that the passage is open.
When driving through an intersection, drivers should be aware that pedestrians have the right of way. So, for example, at an intersection a car turns right at a green traffic light, while pedestrians crossing a perpendicular road also see a green light. In this case, the motorist is obliged to let all pedestrians pass and only then continue driving.
What is a "green wave"
In large cities, traffic on highways is accompanied by a large number of traffic lights that regulate traffic. A traffic light, the colors of which are known to everyone, switches them at certain intervals. This frequency is adjusted automatically and ensures the safety of vehicle movement.
The “green wave” is tied to the speed of the car. It is assumed that, moving at a certain average speed, the driver, having encountered a green traffic light, will also encounter a green light along the entire length of the highway. The three traffic light colors switch at regular intervals, and there is consistency between a number of traffic lights. At all intersections of the route, coordinated according to this principle, there is the same cyclicity.
The “Green Wave” was developed for the convenience of passing intersections; technically, this is not particularly difficult to implement. As a rule, on such highways additional signs are installed with the recommended speed, which will ensure non-stop passage of intersections.
The three-eyed traffic light is an assistant to the driver and pedestrian. The colors switch in order and adjust the progress, ensuring the safety of all road users. By following them conscientiously, you can avoid serious accidents and unpleasant situations on the roads.
