it increases with let's place, as well as the appeal of citizens, uh, and uh to our service is also declining, so well, we are planning that as soon as possible. we will try, uh, to give clean water to consumers. and at present , while work is underway , our specialists carry out control at socially significant facilities in order to monitor compliance with the regime at food units. here, to prevent the worsening of the epidemic situation. well, the inhabitants of pervomaisky partisan soviet district. we recommend for the time being to use bottled or imported water in educational institutions that are in the zone of influence of the accident, supervision specialists control the process of cooking and compliance with personal hygiene conditions. 12 years since the tragedy on september 7, 2011, the lokomotiv team died in a plane crash, which was heading to the match of the continental

hockey league against minsk dynamo , there were 44 people on board the plane, among whom were three belarusians ruslan soleil sergei ostapchuk and nikolai krivonosov, and today, on the anniversary of the day of the tragedy, central entrance to minsk arena hosts an action in memory of those killed near yaroslavl on september 7, every year we remember all the guys of all hockey administrators, the whole country remembers this. yes, this is really a huge brother for our hockey family for the entire hockey community. we remember them, of course. ruslan soleil was, yes, a permanent captain. yes, such a leader on the site in everyday life and everyone reads the memory of him, everyone constantly remembers. yes, not only on this day, the national team of belarus with the dynamics always put him in jail will work today until 10:00 pm. everyone can almost commemorate the fallen team. at

19:00 more information see you soon. we have kept the peace on the belarusian land, not a single belarusian soldier during the time of independence set foot on a foreign land precisely for the purpose of waging war danish work, in fact, but to live without war, because it is necessary to completely immerse yourself, yes, and work in this situation. this is, of course, the cruelest tragedy of our century. this is the division of minds, the division of the people only in unity, only in honoring their understanding of the origins. don't forget history. don't forget your origins. and then we'll move on. now, if we belarusians will treat our state, our city, district, yard, as a common cause and work on this. i think that

we will avoid war in the project objectively. do not miss the new releases on belarus 24 tv channel. each of them chose his own path , correctly disposed of his talent, successfully implementing it in his homeland. it probably serves to play a lot, because the range of action is not wide enough. today they are the pride hope of belarus here it is. new can be rebuilt immediately with rest immediately on the goal immediately to study immediately to new knowledge. let's share a story, and they are not afraid of their creative path with all the successes and failures and daily work on themselves. nothing is shy. he likes he enjoys what he does, see the project new people on belarus 24 tv channel. i

consider the main task of a teacher to raise a worthy generation so that our country can develop in peace and creation. i was born in the city of ivanovo, brest region. graduated from school number one entered brest pushkin pedagogical institute and after graduating from the institute, i returned to my city, because i love it very much. it is not expensive and will remain expensive. i have always been a teacher for 30 years. and if i had the opportunity to rewind time, then, probably, i chose the same professional path. the most interesting profession is promoting the child. so, when they come to us in the fifth grade and we study their abilities

, their needs, mentally imagine how this child can develop the teacher must be demanding, be able to be happy for the children instill in them faith in their strength. the most valuable thing for a teacher is when his students reach heights. this is a great reward for me, that at the same time i feel, of course, pride, joy, working with modern children. i would like to lay in them, first of all , responsibility to myself and to the outside world. until a person begins to demand something from himself, he does not have the right to demand something from others, the child must understand that he goes from the parental family to school, and he represents at school in society of his family. and the family is the most valuable teacher's work for me - this is a mission, sometimes this mission is difficult, but it should be. not a mock-up and why

not me on the other hand is an opportunity for self-realization. and when you do a lot at school, then azar comes and with this excitement you capture the children. let not all of them, but many of them and then these children are grateful to you for the fact that you tried at the right time. well, give them some kind of acceleration, and they began to develop as i saw it. papa what are there specialists waiting for him permission of the inhabitants of the metropolis spends about 6 months of his life, he has a personal day in the calendar of international holidays - this is the fifth of august and even a monument, or rather two in london and novosibirsk in japan

, initially they had blue instead of green, and in berlin one such device still has as many as 13 light signals. surely you have already guessed what i am saying? i'm talking about traffic lights. and if you think you know about him, all in the next half hour. we will try to convince you of this and once again to prove that science is next to judge ekaterina beretskaya. hello. and don't miss out on the program. from a primitive semaphore-based device to a modern automated control system, let's traditionally start with the history of the issue red yellow and green. why did you choose these colors? and the green wave at rush hour, then they are the conductors of traffic flows. the first

traffic light in history was installed over 150 years ago. but where and how he looked, i will tell you more directly. now the first traffic light has been installed in london near the building of the british parliament designed it john peak. knight , taking as a basis the railway semaphore , the device turned out to be a primitive tower type, with two semaphore arrows controlled manually. true, even then, with the onset of darkness, the apparatus was illuminated with the help of a gas lantern common for that era. by the way, it was his explosion that led to the fact that the tower was dismantled and not used for about fifty years at the beginning of the 20th century. in fact, a new stage in the history of traffic lights begins, they were automated, then

semaphore wings were replaced with light ones signals and connected the device. in 1920, in detroit and new york, the tricolor traffic lights already familiar to all of us were installed in the twenty-second year. the traffic light reached paris and in the soviet union the first traffic light was installed. don. at the same time, those traffic lights worked on the principle of a mechanical clock. but the arrow did not point to time, but to a colored field, however , it was the so-called electric lights with a vertical arrangement of lamps that soon came one nuance is the arrangement of flowers. in this design , green was the first inverted, then yellow and lower red, everything fell into place familiar to us today and in the fifty-ninth year of the last century , when a large country joined the international convention on road traffic.

well, the first electronic traffic controller in our country appeared in minsk in 1938. at the crossroads of kirov and bobruisk streets with the history of the issue figured out, it's time to figure it out. why do traffic lights shine for us exactly red, yellow and green, and not, for example, blue or purple according to what principle electronic traffic controllers are installed on the roads of our country and who exactly controls everything in order, our correspondents are already ready to tell. the reasons why the colors familiar to our eyes were chosen for the work of the road automatic adjuster, somewhat in the air, the intensity of plants is inversely proportional to the fourth power

of the wavelength, therefore, the shorter the wavelength, the less this color is scattered. therefore greater distance. he sees, if taken from red to green, the wavelength decreases . red is the longest wavelength. this is about 670-700 nanometers. yellow - this is somewhere in our region, it turns out 580 there . so we have a green maximum sensitivity of nanometers - this is 550 mm. that is why in bad weather, such as rain or fog, the prohibition signal will be visible farthest, in addition, explain the choice of these colors. it is possible even from a psychological point of view. it's all about associations: red is a danger to us, and green, on the contrary, means tranquility and tranquility. if we talk about the installation of traffic lights, it all depends on the analysis of the flow of traffic and pedestrians at the intersection. the principles of traffic organization and

the design of traffic light objects described in the technical regulatory documentation. will carry out maintenance repairs and operation of the traffic light facility. it's in the city of minsk uh utilities unitary enterprise specialized in assembly and operation of the mountain colonel employees of this enterprise work with the traffic police and at the central traffic control point, in short, the soup is here and responsible, so to speak, conducting traffic flows. monitor the state of the traffic situation in the city of minsk, this control is carried out both by means of video surveillance and interactive maps, if necessary, we intervene in the operation mode of traffic lights objects. somewhere we increase the green signal burning time for any direction

of movement. soup also monitor the status of traffic lights in real time. and if any traffic light fails , a red circle lights up on the dispatcher's screen. you can also receive information about the employees of the state traffic inspectorate, as well as from citizens by phone or by appeal, including those received through the electronic portal object and submit an application for elimination? and if now, when traffic lights have become electronic, typical, breakdowns are associated with software, errors, problems, with power or with radio equipment battles, then earlier problems were reduced to wear of contacts and lamps, by the way, it was the shape of incandescent lamps

with round, glass, flasks , which were installed inside each section of the road assistant, influenced the widespread use of the round traffic light that is familiar to us. science project is on air today we are studying traffic lights. and here's more about what we will tell you when auto traffic becomes an object of research about scientific developments for the benefit of our security, we will talk with a guest in the studio. emphasis on the comfort of road users and on the environment and another experiment of the science project nearby , the correspondents of the program spent several hours as part of a repair team.

the west editors' club has completely isolated its information space from the unclean belarusian and russian opponents, very uh, smart, very rich and very efficient, so it's not just this one frantic. i am propaganda, and by showing stories, sorting through the shelves, you can understand this matter, and here are the viewers and our task. think while they write their manuals. we, too, must look at this and write our own anti-winds for the second european states, that is, reduction to the level of insects. what kind of justice are we talking about, in principle, if the united states of america has not joined, er, the roman status ? internationally, it is not that it is perverted, it simply does not exist, it will always deceive and go

to any violation. don't miss out on tv channel belarus 24. sport, like life , consists of back questions, the answers to which you will find in our program. this is a program about sports that needs to be watched with the mind. the participants of the program will fight in the battle of the mind. the answers are ready. which football club in italy is nicknamed violets. what kind of sport according to the famous song, the coward does not play the coward does not play hockey absolutely right for the correct answers. they will earn points, and for the wrong teatti. what is the most athletic female name in the olympics. what kind sports? again mikhail and swimming, and biathlon

what color is the cue ball in snooker? stanislav beliy watch the intellectual sports show head game on the belarus 24 tv channel about how traffic light modes depend on traffic. we found out, and that's how this traffic should be. what scientific developments do our scientists have in this area, we will ask right now from our guest evgeny nikolayevich hello ekaterina evgeny nikolayevich, i propose to start by clarifying the garden according to the terminology in our topic. yes , because it is found in various sources, besides a traffic light, for example, a traffic light object, and a traffic light system is a traffic light control system.

here, so that it is understandable and accessible, so that no one confuses the traffic light , this is familiar to all of you, all this signaling device that we are used to seeing on our streets, roads, either three-color for drivers, or two-color for pedestrians, that is, traffic lights. we have normatively defined nine types of traffic lights, two types of pedestrian traffic lights, but they all comply with the convention of road sign signals, because belarus signed the convention at one time, therefore, moving to other european countries, at least a large number of you see those traffic lights we are similar, these are just the means of our convention on signal signs, to which we are also, respectively, a traffic light object. this concept is more complex, it is already more professional. that is, it is just a system or a set of equipment that allows you to ensure the correct coordinated operation of traffic lights at a crossroads or a descriptive crossing there, as a rule, none a traffic light is very rare, where there is one traffic light - this may be a customs terminal entering the transition program. and so, as a rule, we have several even several dozen traffic lights on a section of the road network to regulate traffic, so that they work in concert and there are no

overlaps. god forbid two greens were spinning in the direction the time is calculated for each of the signals. this is a complex of equipment, which is called a traffic light object and the center is a traffic light control device, which is called a road controller. all traffic lights are connected to it. there, for this, a large cable industry needs devices to put traffic lights. that's right, as it should be, all this is just everything, here it is the complex. we have almost 2,600 traffic lights in belarus , and traffic lights, if you count all of them next traffic light, it's a traffic light, but if when the number of counting, then the number of traffic light objects to count correctly according to the number of traffic light objects is in the lead, of course, there are 870 of these objects in the capital. well, then pissed cities, everything is together there. they also give the same figure, and in total, we

have a regulation traffic light in ninety-three settlements, and in recent years it has begun to be actively used, including outside urban suburban areas. minsk is not rural for us, settlements are considered, there are a lot of traffic lights and on highways pedestrian crossings and some crossroads have begun to regulate traffic light also traffic light control system road controller and all traffic lights object is a minimum level first level control system. if we need to ensure the coordinated operation of several traffic lights for this already. a higher level control system is being built called the acs of the automated traffic control system, and then they ensure the operation of already traffic light objects in an agreed mode, for example, the green wave, or there some other modes. for this , a higher-level system is already needed, including the largest non-indian systems we have in all regional cities in bobruisk and in lida since we already said about the green wave. let's tell you how it happens and there is still such a concept, again, but zelenaya street read different concepts.

yes, this is green street - this is a special regime that is used when it is necessary to ensure the passage of some kind of delegation, that is, then turn on the green in that direction, in by which the delegation is moving, everyone else is told a red signal, then the time until the escorted column passes here, and the green wave is when such a mode of movement is provided for the vehicle, when they arrive at the next traffic light object on the green without stopping there are no additional stops less delays less stops less. resources, respectively, the traffic mode is getting better, we try to do it wherever possible, where it turns out the green wave, but here we have big planning restrictions, before in total, if the crossroads or write to the crossings are located at small distances, or at different distances. green wave, ideal does not work in two directions. she turns out perfect. if everything is thought out in advance at the design stage. these are examples of berto, including when it turned out that it is perfect in both directions, that is , it is calculated for a speed of 40-50 km / h and it

turns out to be almost ideal for all directions. and so, if in real conditions you have to adjust the time of day where there is more flow, we give that flow a green wave in that direction, for example, in the morning to the center on our radial streets, and in the evening more fat wave is better, we better provide in the direction that the wall leaves. yes, respectively, the counter then turns out. well, sometimes it turns out not at all a green wave, the light of a traffic light turns on. by science. and yes, as we, as we take out, studied your scientific biography a little, let's say. here i was interested in the monograph coordinated traffic management . eh, one of the authors. that's just building a green wave. how to build it? how can it be done? what parameters are needed for this? what initial data is needed to make it good. you came up with a diagram, this is just an example. that's an example. what is the name of the graphical representation of this green wave tape well, the so-called non-stop movement, if the car moves in this direction. yes, it will

run non-stop. if he hits another time at a different speed, so it becomes all the same he will arrive for us with his group of the car that was driving calmly, if he drives faster, and those who drive evenly will pass the green signal to the second one at the next intersection in order to calculate all this. that is , you learn, probably, the intensity, the bite. yes, of course, the time of day. correctly we live according to the cec why, therefore, the intensity it also depends on us, what else is the composition of the traffic flow, the speed of their movement. it changes all the time, the more. density, it turns out the speed drops and vice versa, the free mode of movement. but we tend to green wave well, it turns out in urban conditions at a speed of approximately 40-45-50 m / s. you don't need to go faster. if you go faster and you catch all the reds below 60. but about 5,000 - this is if you go 60, you can drive one or two, and you will stop at the next one, and the one who will go 50 where the green is, she works, it will pass. everything i

do sometimes i drive along independence avenue , entering from the side of the rescue, and i reach surganov street, not a single stop. of course you know, if i also taught, you have another monograph, as far as i know, well, you again, yes, one of the authors. yes, that's the definition of traffic losses. here is the concept of loss. well, you know right away some such, well, not very good pictures, eh. theories, uh, does that mean there's an accident? well, that is, some kind of term was introduced by the founder of science, should the movement in belarus by vrubel andreevich back in the eighties of the last century. this is in our then polytechnic institute. now the university. we develop it further than the bed we were again, then. he led this concept, which means that this is the cost of costs in the process of moving above some optimal level. well, for example, we have a delay. each hour delay costs conditionally 15 rubles. stopping by car costs, for example, 25 kopecks. kilometers, overrun also cost some

money. here we just consider all these natural indicators for variants. here we calculate their cost. and here we compare with the optimal level. this difference will be called losses. therefore, such a name turned out, that is, it needs to be explained, but it has already developed like this. we are used to it, but for a fresh ear, eyes. probably it should really be explained. we have four types then in the methodology. this technique is used to assess the quality of movement. the less loss of all the better. that was some kind of goal. so it provides for four components of economic losses, that is, delays in stopping fuel consumption overruns environmental losses. you noise, vibration emissions including the loss of this accident rate is what we know the most, as we just according to our estimates it turns out that if we calculate the loss of traffic accidents they are total the sum of traffic losses is approximately 7-8% only they are the biggest they themselves see and know best of all the rest is distributed to everyone. that is, when we calculated it according to the most underestimated estimates. these are billions, this is billions per year

, according to estimates in the russian federation, where it has already reached the normative level, they have losses from accidents, only accidental losses. up to 2% of gdp therefore, if they are reduced by at least half, then one percent of gdp received, including the fourth component social loss, while the most undeveloped. here, the human factor is taken into account , the relationship of traffic participants with each other with the inspector, that is, extra negative emotions, etc. we are also trying to take this into account here, while we are at the stage of developing money. we have not yet been able to recalculate this. why do we recalculate the money, that it is possible, for example, to compare economic environmental accidental losses with each other, it was necessary to have a single base. this base was just adopted, while the monetary base is used to evaluate options, and in this the case very often turns out where the lower emergency losses are done. everything is safely put all the left sections of the traffic lights. all divorced conflicts. there, economic environmental policies are growing sharply, because delays are increasing and the environment is also deteriorating, therefore, it is necessary

to compare options, calculate one second , compare with each other and then understand the solution which one should be implemented mainly outweighs safety? but in some cases, you have probably already heard the installation of artificial bumps. do you know which one already people themselves and even without our calculations. in some cases, they begin to protest, write, they complain, they put an unevenness, for which, in order to reduce the speed to be higher than safety, worsen, the noise worsens the environment, if this is in a game of individual buildings, people already feel it themselves, they begin to complain, that is, therefore, this it is always necessary to compare different types of losses . they make a decision, of course, taking into account some other additional factors, but this level of assessment must be obtained. and here we are somehow it was calculated just by the irregularities according to the artificial comparison of traffic lights on the street, where we have 300 cars per hour passing in one direction , it is cheaper to put the irregularity, but after 3 years the delays and stops at the traffic light object will be less than on this irregularity. the same car should and

there already the total loss will be worse. therefore, uneven places. well, in my opinion. this is exactly in the yards on those streets where the speed is 20 km / h. that's where they work well. there they support the street mains to endure. and why them what do they put cheaper than traffic lights the cost of a traffic light object pleasure is not very cheap minimum crossing 150.000 rubles. and the largest objects of the crossroads are large, that is , it costs up to 350-500.000 to build such and such a huge object, therefore it saves the starting part. but then, just the loss of road traffic irregularities is much larger and overlaps what would have been at a traffic light. i don't know the last question. perhaps in philosophical terms, every year there are more so-called ecotransport. yes, they are electric cars. these are unicycle electric scooter bicycles. again, for the environment , of course, this is probably much better than the usual familiar transport.

as for the principles of traffic organization in general, it has become more difficult to analyze all this and draw some conclusions, or maybe, in general , everything will have to be redone soon, if it is like a mechanical vehicle that they drive on the roadway from the point of view of organization. you no longer require radical changes take into account that there will be less noise, there will be less environmental losses from emissions, but due to the fact that there is less noise, they are less audible, that is, there is a danger that they are not visible in the yard, for example, you will not hear them at all, including , but, in principle, electric vehicles, if especially if there will be electricity for them. produced from clean sources, then, it is always better for the ecology of road traffic. well, in general it will be better. but as for low mobility, it means that here we have already encountered problems, which is obvious they require the so-called, as i call it, intermediate infrastructure, that is, they need to drive on the roadway. it is dangerous for them to ride sidewalks dangerous for pedestrians.

they need an intermediate and here is cycling. when in 2006 in belarus we took the roadway to the sidewalk then it was much smaller and just in case, according to estimates, about 700 cyclists did not die over the years, because they were removed from the roadway, but now increase their number. and now, especially given the means personal mobility has become bad for pedestrians, damn it, pavement. that is, here i see that here we will have issues with the organization of traffic , including regulatory and traffic rules . many of these injuries. on the sidewalks with pedestrians turned out, that is, because this is a very special group of traffic participants. they are already at high speeds. training bad followers to the driver teach pedestrians how to walk slow is conditional, but here they can already go fast, and at the same time, preparation for well, everyone has their own, so to speak, so here, that we

will still have questions on micro mobility. it will be necessary to adjust, including regulatory approaches and our technical ones. thank you, i wish you good luck, it was really very interesting, and right now on the air is another experiment of correspondents of the science project nearby, this time my colleagues wondered who and how repairs traffic lights. each of the heroes of the project is engaged in a very important matter. my name is elena olshevskaya. i deputy director for tourism of the berezinsky biosphere reserve. my name is alexander bodgusain, and i am the general director of the national olympic stadium dynamo, a stadium born for your victories. we will introduce you to people who have found their calling for me stadium dynamism part of life. it is not an easy task to lead such an arena, we offer to spend one day with specialists and learn all about the intricacies of their

work. the reserve has a very large species diversity, both plants and animals, because the main task is to preserve nature for the present and future, watch on belarus 24 tv channel . the first signal about the termination of the work of the road assistant in a given mode is seen in these walls, and specifically, the dispatcher of the central control point, the reaction , instant information about the malfunctions is transmitted to the nearest crew on duty. an emergency brigade is leaving, staffed with experienced electricians, engineering and technical workers. equipped team in accordance with all safety rules,

for example, an electrician without a helmet of a bright vest and a safety cable directly it will not even approach the object, that is, the traffic light. after arrival , the obvious identified defective is eliminated, and complex measures are also taken - this equipment testing is checked for the correct switching of signals prohibiting to allowing and from allowing to prohibiting. the honor of these works is carried out directly inside the road controller. the road controller is checked, its operating mode is checked, it turns on in the yellow flashing mode, then the red circle mode turns on and it is checked how it works the object and then it is included in the program and the switching of signals looks

like it switches how it works at the busiest intersections of the city, during the work of the emergency team , traffic police officers come to the rescue. they also regulate traffic during the so-called two scheduled traffic light outages. the most important thing is that it is necessary to check pedestrians so that they work properly, so that a pedestrian can pass them with us. with sound, talking traffic lights or a scientific device with a speech informant are primarily aimed at pedestrians, who have vision problems. an additional function is the risk of additional problems, however, as experts say, these risks have already been studied, despite the fact that such traffic lights are still in test mode. well, as it turned out, in the area of ​​​​responsibility of employees, a specialized installation and operating company, in short , smep is not only traffic lights daily for

the maintenance of technical means of organizing traffic - these are road signs , road fences traffic lights for facilities road controllers detection means employs at least 20 crews, staffed by experienced road electricians. and once, when it all started back in the distant seventy-fourth, they say at the enterprise there were a little more than 30 people in the state, but the volume of work was smiling . much more modest over the years, only road signs in the capital have become 25 times more. today there are almost 90,000 of them, and there are more than 780 traffic light objects against some 65 back in the mid-seventies of the last century. you go fast, you go slow, it's all the same.
