We are not used to seeing traffic cones that place themselves. They are already testing them in China

by

A traffic cone that rolls out of the emergency vehicle alone, is placed in position and forms a safety perimeter before any operator has set foot on the asphalt. It is not a scene that we usually see in our parts, but the truth is that in China they are already testing it and its operation is tremendously interesting. What is happening. Emergency teams in China are testing autonomous traffic cones capable of securing the perimeter of an accident in less than ten seconds. Such as describe Marc Theermann, director of strategy at Boston Dynamics, in a post on LinkedIn, these robots leave directly from the emergency vehicle and move alone to their position, forming a safety barrier without any operator having to cross the road. They can be activated remotely or operate completely autonomously. Click on the image to go to the post The hook: the safety of the operators. Placing cones by hand on a road with active traffic is a truly dangerous task for operators in charge of road maintenance, or those carrying out work on the road. The idea with this technology is simply to eliminate or reduce as much as possible the human presence in the most vulnerable phase of any road intervention. How they work. Researchers from the Center for Research in Technologies, Energy and Industrial Processes of Pontevedra (CINTECX) published a study in 2025 in the magazine Infrastructures that described the design and validation of its “Remotely Piloted Safety Cone”, a robotic system with a similar architecture. The device combines autonomous GPS navigation with RTK correction (a high-precision positioning system), odometry sensors, an inertial measurement unit and ultrasonic obstacle detection. All of this managed by an autopilot and an on-board computer that coordinates movement in real time. The results of the study showed that the most precise configuration managed to stay less than 20 centimeters from the planned route, a more than acceptable margin for this type of operations. Faster than by hand. According to that same studythe estimated placement time per cone with this system is around three seconds, compared to the seven or eight seconds it takes on average for a human operator. In an intervention that requires dozens of cones, the difference is quite significant, especially if this is then combined with systems that can be placed simultaneously and not one after another. And also at night. Best of all, the task can also make it much easier to place cones when there is barely any visibility. And the robotic cones incorporate lighting, something basic for any type of emergency road signage. In Spain we already propose the “less intelligent” version. After the V16 beaconswhich have given a lot to talk about (more for the bad which for the good), the DGT has also explored the use of connected coneswhich would be responsible for notifying in real time of road works or dangers. They would be integrated into the DGT 3.0 platformalong with the V16 beacon, although they are still in the testing phase and very far from implementation. The main difference, as you might expect, is that these cones do not move or position themselves. But it’s already a step. What comes next. The natural step of this technology is not the individual cone, but rather several can be coordinated at the same time, something that we have already seen in tests in China, and that the deployment is reminiscent of that of the drone shows in the sky (less glamorous, but just as addictive to watch). The researchers they point in his study of multi-agent swarms, several robots working together in a coordinated manner, such as the evolution of this technology to apply it in infrastructures.

What is this network traffic analyzer and how to use it to detect Internet problems or security flaws

by

Let’s explain to you what it is and how to take advantage wireshark from the point of view of an ordinary user. I say this because it is a very advanced tool that analyzes all the traffic on your network, and that of all the devices connected to it. When you run this appyou’ll see a series of lines of data that you may not understand. But by knowing a little about what information is going to appear, you can also find ways to diagnose failures in your connection or whether an application or device is spying on you by sending data when you are not using it, or to unknown servers. What is Wireshark Wireshark is a network protocol analyzerwhat in English is called packet sniffer. What it does is capture, isolate and transmit each of the packets that are sent and received through our Internet connection, whether we are connected via WiFi or Ethernet, and it does all this in real time. This is a free and open source programwhich means that any developer can look at how it works inside. This makes it reliable and safe, because if it did things that were not appropriate, users would have already reported it. It has versions for Windows, macOS and Ubuntubeing able to download them at wireshark.org. When it comes to giving you information about the traffic that passes through your network, shows you very important datasuch as the IP and Mac addresses of the person sending or receiving the data, the sending protocol, the content (showing text or images if they are not encrypted), and connection healthwith the exact time it takes to load each piece of information. The operation of this tool is based on three fundamental pillars. First the capture one, because it puts your network card in a mode where it can see all the traffic that reaches it. This includes both information that your operating system displays and information that it does not display. It also has a color code to help you distinguish the packages. As a general rule, green is usually standard TCP traffic, blue is DNS or UDP, and black and red usually indicate problems. That’s why, you can identify that you are having errors or problems quite visually, just by seeing that there are many red or black lines. The app also has a top bar where you can type commands to filter information. This is already quite advanced if you don’t know how networks work, but you can, for example, use “ip.addr == IP Address” changing the address to that of a specific device to see its movements, or type “http” to see only web traffic. In short, it is a fairly complex and advanced tool, so it is not for all users. It is more aimed at system administrators, to detect attacks or bottlenecks. However, If you know where to look you can also take advantage of it as a home user. How you can take advantage of it Although it is an advanced tool, it can be useful for normal users in some contexts as well. We are going to give you some ideas so that you know the type of information you can obtain: If your online games cause problems: A speed test may tell you that your Ping is good, but the experience is different when playing. Therefore, this application can tell you if packets are being lost along the way that are making everything slower. If you are concerned about privacy: You will be able to see what data your devices send to the cloud and the Internet, and if it is not encrypted you will see your content. This can help you be more aware of your privacy, and detect if a device is sending more data than it should. You will also be able to see if a device connects to servers of dubious origin. If you have technical problems: If a website does not load or a printer disappears from the network, this application can show you at what point communication is being cut off. If you want to do lag tests: If in this tool you filter by the appropriate protocol, such as UDP for games, you will be able to find if there are black lines that indicate that the information you send is “out of order” because it never arrived at the destination or did so late. With this you can see that if you have lag it is not a matter of your bandwidth, but perhaps of your network signal or a saturated node of your operator. If you want to know what the devices on your network are doing: As we have more and more connected devices at home, with this you can audit what each one does. You can even isolate the IP of a cell phone or a security camera to know if it is connecting, what data it is sending, or if, for example, it sends data to other servers from time to time. In any case, what you should know is that this tool is going to show you all the traffic that your home network has. It shows all the raw traffic, and doesn’t hide anything, meaning you can have a lot of fun looking at everything that’s happening on your network and learning how to take advantage of it to understand everything.

Taking an important call in a traffic jam is the order of the day. In 1990, a company in Barcelona already offered this service

by

Nowadays, as soon as we have some down time, we turn to our mobile: either to scroll infinitely on Instagram or to catch up on email. Although what defined the basis of today’s smartphones was the first iPhone in 2007, the professional point began before, with the blackberry 5810 and your email in 2002 or we can even go back to Nokia 9000 ’96, which introduced the keyboard and its business approach. The late 90s were the beginning of turning the mobile phone into an everyday object. I’m driving and I need a call now. Of course, back in the 90s, carrying a cell phone in the car and answering a work call was unthinkable. Or not, because someone thought of it an exclusive telephone service for drivers in Barcelona pre-Olympic Games. The target audience was those people who were so busy that they could not afford to be disconnected while traveling through the congested business areas of the city. The operation. As they narrate on the Catalan regional television 3Cat, if in the middle of a traffic jam you were lucky enough to find one of those people in white overalls on a scooter, with a fanny pack and the phone stuffed in a shoulder bag, you could ask them. A uniform as characteristic as the backpacks of today’s delivery drivers, but much less common: at that time there were only five workers moving through the busiest traffic points in Barcelona, ​​although they wanted to increase it to 25. If you are standing, they leave you the headset. And if you move, they lend you the device and follow you until you complete the call. The price of the service was 25 pesetas and the minimum call price is 300 pesetas. Because? To begin with, because in 1990 if you wanted to call on the street what there was were booths and analog technology, in Spain specifically MoviLine: the first mobile operator to deploy the original 1G network, owned by Telefónica. And if we talk about devices, the mythical Motorola MicroTAC It was a status symbol for executives. A symbol measuring 23 centimeters and weighing 350 grams. Yes, there were some mobile phones, but they were heavy, with very long antennas and batteries that barely lasted a couple of hours in conversation. On the other hand, having a phone installed in the car was expensive and niche. But the business was not just the telephone, but mobility and time. As businessman Josep Marí says, his idea was “to create the need to find a mobile phone to be able to call to work, home or wherever.” Ahead of his time. This “Automatic Mobile Telephony” service was ahead of its time in that it had a vision of a future need, but faced a market that was not yet ready. As the 90s progressed, telephone technology became more refined and democratized. 1995 brought GSM to the Spanish state on the one hand and, on the other, the liberalization of the telecommunications market, which inaugurated airtel. The operators began to directly control distribution and technical service with franchises and distributors, leaving little room for local independent companies. Scooters before the scooter craze. And if the service itself is surprising, so is the means of transportation: a scooter with a gasoline engine, more specifically the Sport model. of the Go-Ped brand, but quite similar in design and concept to the electric ones that swarm our streets today. His virtue was exactly the same: moving quickly and agilely through the density of Barcelona’s traffic to be able to get in front of the client.

traffic jams, collapsed buses and 400,000 people without a planned alternative

by

Closed with a message at midnight and no backup plan. This is what the 400,000 people who take one of the Rodalies trains in Catalonia every day have found. The railway system has come to a complete halt after the an accident in Gelida (Barcelona) in which a trainee driver died and a second train derailed, this one without consequences, between the stations of Blanes and Maçanet (Girona). What has happened? Last night, Rodalies Catalunya reported that a train on Rodalies line R4 in Barcelona had suffered an accident. In it, everything indicates, a retaining wall fell on the train as it passed. On impact A 28-year-old trainee train driver has died and 37 injuries have been recorded, of which five are in serious condition. Furthermore, between the stations of Blanes and Maçanet (Girona), a few hours earlier another train had derailed. This time as a result of a landslide that left some rocks on the road. In this case there have been no victims on a train in which only 10 people were traveling. Click on the image to go to the original tweet Rodalies closes. A few minutes before midnight, Adif confirmed that all Rodalies lines in Catalonia were suspended until the status of all the lines was checked, but assured that, when it was verified that there were no obstacles on the tracks, the service would be restored. This morning, the trains have not left the depots. Rodalies confirmed that the train service will remain suspended until Adif checks the status of all the tracks. Rodalies points to the damage caused by Storm Harry, which has left heavy rains in Catalonia and has even been warned of flooding. The stoppage also comes after SEMAF (Spanish Union of Railway Machinists) will release a statement announcing that they are going to call a general strike in the sector and that they would stop the service if security was guaranteed throughout the Catalan network. Click on the image to go to the original tweet 400,000 people. Every day, around 400,000 people move around Catalonia using the Rodalies service. Today, Wednesday, January 21, they learned that there are no trains to get to work or drop the children off at school. But, above all, there is no alternative plan to replace the trains, so passengers have to find their own means to get around. Rodalies has 134 stations and its 462.7 kilometers of tracks cover the most extensive Cercanías service in Spain. In total, it is made up of 13 Cercanías lines and 6 regional train lines. The Barcelona Cercanías service, with six lines and two branches (R2 Nord and R2 Sud), is the most extensive. a challenge. The suspension of the service without alternative measures anticipated a chaotic day in Catalonia and, especially, in Barcelona. And the forecasts have been fulfilled. In The Country They note that many passengers were not aware of the measure when they arrived at the stations and that they were not offered any alternative there. In The Vanguard They collect complaints from passengers who are not being told when service can return. Some of them, they point out in the newspaper, have waited for an hour at the stations for trains that have never arrived. It was not until 7:00 when the stations closed definitively. From early in the morning, bus services are saturated in Barcelona. In 20 Minutes They collect the voice of a driver from Barcelona, ​​who assures that “it is chaos. Normally we are always full, but today even more so.” Given the difficulties students face in arriving, the University of Barcelona has canceled all exams. The rest of the universities in Catalonia maintain normal activity although they have asked students who cannot travel to an exam to contact their teacher as soon as possible. For now, the only alternative proposed by the Generalitat It is the recommendation to prioritize teleworking wherever it is allowed or possible. The roads. On the roads, Trànsit has chosen to raise the toll barriers on the C-32 south in both directions of travel. To the suspension of Rodalies we must add the impact on traffic on fifteen roads (ten of them are cut off by floods or landslides) as a result of the storm that is hitting the autonomous community. In The Newspaper They report that all accesses to Barcelona are jammed or have been jammed early in the morning. In addition, various accidents have made traffic even more complicated.

wants to connect all traffic as they already do in China

by

The connected V16 beacon becomes mandatory on January 1, but the DGT already suggests that this device would only be the first piece of a much more ambitious project. The director of the organization, Pere Navarro, advanced in an interview in Public Mirror that will soon arrive “the connected cones” and other smart signage elements. And that makes perfect sense, since in the end the objective is nothing more than minimizing the risk of accidents through an interconnected traffic network. Something similar to what is already happening in other countries such as China, Singapore, Japan or South Korea, among others. A fully connected traffic network. If we insist on the example of China, applications like Amap, its equivalent to Google Maps, allow drivers to know how many seconds are left before a traffic light turns green. There they have all their road infrastructure connected. Traffic lights, traffic cameras and the vehicles themselves are part of a digital ecosystem that intends to improve traffic and reduce accidents. Europe, and specifically Spain with the DGT at the helm, seems to look towards this model as a long-term reference. The DGT 3.0 platform as the brain of the system. Behind the connected V16 beacon is DGT 3.0the digital platform that acts as the nerve center of this entire smart network. When a driver activates his beacon after a breakdown or accident, the device sends its position through IoT networks in approximately 100 seconds. This information reaches DGT 3.0 and, from there, is automatically distributed to roadside information panels, navigation applications and other connected vehicles. Pere Navarro insist in that the system does not collect personal data: “When you buy the beacon, you are not asked for any information. We don’t even know the vehicle’s license plate.” “The DGT does not want to know where you are at all times, the beacons have not been created for that,” as stated on Antena 3. Smart cones, next step. Navarro confirmed that connected cones will arrive after V16, designed to inform about workers on the road, sports events, demonstrations or special transportation. These cones will work with the same logic: when activated, they will send their location to DGT 3.0 so that the rest of the drivers receive warnings before reaching the conflict point. The objective is to gain reaction time and avoid risky situations. The idea is that these cones can also help better manage traffic during events that require road closures, allowing vehicles to be diverted along alternative routes more efficiently. The V-27 signal, warning inside the car. Another element that is part of this connected network is the V-27 signala triangle with an exclamation mark and three stripes symbolizing connectivity. This signal appears directly on the instrument panel of compatible vehicles when DGT 3.0 detects a nearby incident, either due to the activation of a V16 beacon or for any other reason that the agency considers dangerous. Of course, it only works on connected cars whose manufacturers or service providers are registered with the National Access Point for Traffic and Mobility Information. On secondary roads, where there are no illuminated panels, this system can make a difference by providing early warning of dangers that would otherwise go unnoticed. Towards the autonomous car. If the DGT knows at all times where the broken down vehicles, construction cones, smart traffic lights and surveillance cameras are, it will be much easier to have an effective accident prevention system. For the DGT, connectivity is a solution to eliminate unnecessary risks, such as get out of the car to signal an emergency. Whether the systems are truly effective remains to be seen. But in addition to that, all this information can lay the foundations for the arrival of the autonomous car. And these cars need precisely that: detailed, real-time information about everything that happens on the road. Flexibility. Pere Navarro made it clear that there will be no massive sanctions campaigns during 2026 with the whole V-16 beacon thing. “The objective is not to fine, the objective is an improvement in road safety,” he stated in the interview. The director of the organization assured that the agents will apply flexible criteria while drivers adapt to the new system, prioritizing information over immediate sanctions.

We all turn on our emergency lights when we get into a traffic jam. The DGT knows that we are doing it wrong

by

It is more than likely that when you got your license They won’t mention it, but get into a traffic jam It is easy to turn on the emergency lights while braking. It is something almost instinctive, a warning for the one that goes 120 km/h behind you realize that you don’t brake for no reason. And if you don’t, you’ve probably seen it. However, the curious thing is that the General Driving Regulations do not contemplate this action. Because we do it to avoid accidents, but with the law in hand, the use of warnings It’s not what we have to do when we get into a traffic jam.. And yet, there are even new cars that activate them automatically if the system notices that we brake repeatedly. The most curious thing is that it is not bad nor is it a fault. Simply put, the law was written for cars from another era. Although current cars have been eliminating more and more buttons, relegating them to the screensthe emergency lights is one that has remained a physical and tactile piece. It is logical because it is a security element and it is one that we have well located in the control panel. When braking in traffic jams, it is almost a reflex for many drivers to use the emergency light button to warn those behind them of the situation. In fact, some new cars activate them automatically if the sensors (the accelerometer or the brake pressure sensor) detect a sudden deceleration or if the ABS comes into play. If the braking is progressive, they are not activated automatically. The use of emergency lights in a traffic jam: yes, but no (and vice versa) But… what does the law say? As our colleagues remember Motorpassionhe section C of article 109 The General Traffic Regulations of 2003 establish that the correct way to notify those behind us about this situation is: “The intention to immobilize the vehicle or to brake its progress considerably, even when such events are imposed by traffic circumstances, must be warned, whenever possible, by repeatedly using the brake lights or by moving the arm alternately up and down with short and quick movements.” The problem is that theory is one thing, but in practice, if we are slamming on the brakes It is difficult to walk by lifting your foot off the brake.. Much less by lowering the window and warning with signs. It is much easier to turn on the emergency lights, and the person in the back will also see them better than if we put our arm out the window. Why does the law say this? Because it is an article written in another era. It is an anachronism resulting from times in which the ABS It was not so present and in which, to avoid the wheels locking and the car skidding, we did have to lift our foot off the brake. In this way, we were automatically alerting the person behind us. Therefore, the law does not say that we put on the emergency lights in a traffic jam, but they are not going to fine us for it because the DGT understands the good intention when it comes to notifying other drivers about an anomaly in traffic. In fact, the fact that the law does not establish it, but the cars do, speaks about the discrepancy between the “strict law” and reality. The DGT itself advertises it: In fact, here comes the technicality of “whenever possible”a legal hole that protects us when turning on the emergency lights. Now, where it is mandatory to give these lights is when we cannot travel at the minimum speed on the road. That is, if we are in a traffic jam on a highway and we do not reach half the speed of the road, we will have to turn on our lights. Section 3 of article 49 says: “When a vehicle cannot reach the minimum required speed and there is a danger of overtaking, direction indicator lights with an emergency signal must be used while driving.” Will the regulations be modified at some point to reflect the current situation in which all cars launched these last 21 years Do they have ABS? It is not known, but since it is a universal code to alert of the situation, I imagine that it will not be one of the Administration’s priorities. Of course, you have probably found someone who has used them excessively, giving you a scare for no reason when you turn them on in a non-critical situation. And that, precisely, is what happened with some models from the 2000s that turned on the emergency lights automatically, even when braking to exit the highway. For example, early models of Citroen C4 either Peugeot 307 who were ahead of the rest with something that wasn’t going entirely well.

Japan is the only country in the world where the green traffic lights are blue. And the reason is called “aoshingō”

by

Red, amber and green. The three colors of traffic lights around the world. All over the world? No, some particular Japanese traffic lights resist today and forever… the Vienna Convention on Traffic Signs and Signals to which more than 50 States are adhered. Although there are curious absences in it, such as those of the United States or, of course, Japan. This regulatory framework was signed for the first time in 1968promoted by the Economic and Social Council of the United Nations. The text reviewed previous regulations with the aim of homogenizing traffic in as many countries as possible. The last review, in fact, is from 2003 and it addressed the modernization of some signs or the priority rules on roundabouts. The intention is that what we understand in Spain as a Stop is also the same in France or Germany. And so it is, in fact, because all of Europe subscribes to said text. But the most striking absences, such as that of Japan, give rise to curious anecdotes. Like finding traffic lights where the priority of passage is not granted with green, it is applied when the light turns blue. Blue, I love you blue And if you travel to Japan and plan to drive, there is one detail that you should not overlook (beyond the fact that you drive on the left, remember): the green light on some traffic lights is blue. Or turquoise, more accurately. The origin must be found in the language itself. The Japanese did not have a specific word to refer to green. To mention it they referred to the word “Ao”. The problem is that “Ao” It refers to a wide spectrum of colors and among them, as you can imagine, blue or greenish blue or turquoise. Some sources suggest that the word “Midori”, which refers specifically to the color green, became popular during World War II for a purely practical matter when it comes to differentiating both colors. However, a good part of society continued to refer to green as “Ao” and, in fact, it continues to be part of words that are applied exclusively to define green objects, such as aoshingō…which is actually the official word for the green traffic light even though it doesn’t specifically mean green. In 1960, Japan signed its own Traffic Law where this term was collected to talk about the traffic light. This law is, therefore, prior to the aforementioned Vienna Convention and remained intact until 1973 when a ministerial order ended up specifying that the traffic light It had to be as blue as possible within the greenas a compromise measure between maintaining the traffic lights that were already installed and approaching international conventions. The result is that the oldest traffic lights have a more intense blue and the most modern ones have a green tone with slight blue nuances that can remind us of turquoise. However, they are not exactly green because the term “Ao” works, as we said, for both blue and green.

240 km without curves, in the middle of the desert and with truck traffic

by

Imagine driving for more than two hours without turning the steering wheel even a single degree. No curves, no noticeable slopes, no changes on the horizon. That is the reality of Highway 10 (Highway 10) of Saudi Arabia, which holds the Guinness record as the longest straight road on the planet with a completely linear section of 240 kilometers. A highway born for a king. Highway 10 stretches 1,480 kilometers from Ad Darb to the border with the United Arab Emirates, but it is its segment between Haradh and Al Batha that has received all the attention. The road was originally built as a private road for King Fahd of Saudi Arabia, although today it has become a fundamental artery for the transport of goods between the center and west of the country with the Emirates. The Empty Quarter desert as a setting. The road crosses the Rub’ al Khaliknown as the Empty Quarter, the largest sand desert in the world. The area itself explains why it is possible to build such a straight line: there are no mountains to surround, valleys to cross or geographical features to avoid. Just sand and more sand as far as the eye can see. The infrastructure is completely paved and has mainly two lanes in each direction, supporting intense truck traffic that crosses the desert. Speed ​​limits adjusted for heavy traffic. The maximum speed allowed on this highway varies depending on the type of vehicle: passenger cars can travel up to 120 km/h on fast sections, buses 100 km/h and trucks 80 km/h. Although in 2018 were announced Upper limits of up to 140 km/h for light vehicles in certain sections, the constant presence of heavy transport makes maintaining these speeds complicated in practice. A mental challenge more than a physical one. Believe it or not, driving on the straightest road in the world is not as easy as it seems, especially due to fatigue. The monotony of the desert landscape and the total absence of visual stimuli can cause drowsiness and even a dangerous disconnection while driving. Added to this is the occasional threat of camels wandering across the road. So, although the route is ‘easy’ to handle, mentally it can become a nightmare. Not for nothing is it found in Dangerous Roads website. Reinforced security measures. Aware of the risks involved in driving on such a monotonous road, the Saudi Ministry of Transport and Logistics has implemented various improvements safety features, including paved shoulders, reflective pavement markings (known as “cat’s eyes”), protective barriers, kilometer signs, and directional and warning signs. Here the driver’s attention must be vital, especially on a road with so few changes. Other legendary straights. Before Highway 10 snatched the title, the Australia’s Eyre Highway boasted the record with a 146 kilometer straight stretch through the Nullarbor Desert. Although almost 100 kilometers shorter, this Australian road remains one of the most unique driving experiences on the continent. Also noteworthy are roads such as ND-46 in North Dakotathe United States, or some sections of the Argentine Route 40which although they do not compete in length of absolute straightness, offer endless kilometers of visual monotony.

On this island in Japan there is a traffic light that only turns green once a year, and not precisely to control traffic

by

On the small Japanese island of Himakajima there is a traffic light which remains flashing amber or red all year round. Only during one day in May does it change its usual behavior and activate its green light (or blue, as they insist in Japan). This is not a fault. It was designed this way for a reason that goes beyond traffic control. An educational traffic light. The traffic light was installed in 1994 at the Himakajima East Port intersection, but not to regulate traffic. The island barely has 2,000 inhabitants and few vehicles circulate on its roads. The traffic light exists solely to teach children of the place how the urban signals work before they leave the island for larger cities. One less problem. According to explains the Himaka Road Safety Association, which promoted its installation, minors grew up without real experience with traffic lights. Before, they used small models in traffic safety classes, but the children themselves asked “what does a real traffic light look like?” account Kazuo Sugiura, former president of the association, to the local media Asahi. One day a year to learn. Every May, the traffic light is activated for a full day. Third and fifth grade students from the local school go to the crossing accompanied by teachers, parents and authorities. There they practice how to cross correctly: they wait for the color to change, look both ways and cross the zebra crossing with their arm raised, just as they would in any city in Japan. More difficult than expected. The children also discover that calculating the time they have to cross the pass is not as simple as it seems. “It was complicated because it turned red when I was trying to cross,” explained a third-grade student after practicing with her bicycle. The exercise helps them understand the real times of light change and develop security reflexes that they cannot acquire in their daily life on the island. An unexpected tourist curiosity. This little anecdote has gained notoriety beyond Japan. Every year videos and photos circulate on social networks showing the peculiar educational ritual. Some users even consult the local government website to find out the exact date of “green day” and witness the event, although it varies slightly each season. It is already part of the island’s identity. Once the annual training is completed, the traffic light returns to its flashing lights routine. It does not serve any practical function in traffic control, but it has ended up becoming a small symbol of how the community of this island prepares its children for the urban world. The rest of the year, Himakajima remains a quiet place known for its beaches and octopus dishes, with a traffic light that counts down the days until it can turn green again.

There are so many trips planned to the Moon that the UN has created a “lunar circulation committee” to regulate traffic.

by

The Moon is coming into fashion after 50 years of calm. But this time it is not a race between two: it is a commercial race in which old and new space powers, as well as a multitude of private companies, participate. The lunar “jam.” The interest is so sudden that in the last two years there have been 12 attempted lunar missions. This “blitz” of moon landings, driven by public-private programs such as NASA’s CLPS, has proven to be a quick, cheap, but also a little chaotic to reach the Moon. Still, worrying about “traffic jams” on the Moon sounds absurd. Cislunar space (the region between the geostationary orbit of the Earth and the Moon) is gigantic: 2,000 times larger than that of Earth’s orbit. If there is so much room, where is the problem? The problem is that everyone wants the same place. In the same way that on Earth all cars use the roads, on the Moon missions tend to cluster in a very select set of stable orbits. The immensity of cislunar space is, therefore, deceptive, explain professors of International Affairs and Aerospace Engineering at the Georgia Institute of Technology, in an article for The Conversation. To make matters worse. Most government sensors that track satellites in Earth orbit are not designed to detect and monitor objects this far away. The Moon’s own glare makes the task difficult. This uncertainty has a direct consequence: it forces operators to be excessively cautious. When in doubt about a possible collision, agencies prefer to waste fuel and carry out an evasion maneuver, which interrupts scientific missions and shortens the useful life of the ships. 50 satellites are enough for chaos. According to research published in the Journal of Spacecraft and Rocketsonly 50 satellites in lunar orbit are enough for each of them to have to maneuver an average of four times a year in order to avoid a possible collision. 50 satellites may seem like a lot, but at the current rate of launches, we could reach that number in less than a decade. And it’s not theory. It’s already happening. The Indian orbiter Chandrayaan-2 had to maneuver three times between 2019 and 2023 to avoid dangerous approaches (one of them with NASA’s LRO probe). And this occurred when there were only six operational spacecraft orbiting the Moon. The UN wants to bring order. This is where international diplomacy comes in. The United Nations Committee on the Peaceful Uses of Outer Space (COPUOS), the main global forum for space law, has taken action on the matter. In early 2025, COPUOS formally established a new working group: the Action Team on Lunar Activities Consultation (ATLAC). The goal of this team is precisely to create a draft of space “traffic rules.” They have until 2027 to study recommendations and a possible international consultation mechanism.
