In the last century, the traffic light system was manually controlled by the police, and later it only evolved to automatically change lights. Sometimes during peak commuting hours, you will see traffic policemen holding keys to change lights manually next to the traffic light control box. Therefore, the current signal system is still not smart enough. Then, what would the world change if the design of the traffic lights were to be abolished? The Massachusetts Institute of Technology, together with the Swiss Institute of Technology and the Italian National Research Council, made a report and looked forward to the future transportation system. In this set of intersections, the traffic lights were completely cancelled. No traffic light, how to get there? Professor Carlo Ratti of the Massachusetts Institute of Technology stated that the situation at the crossroads is very complicated because traffic in both directions competes for the same place. Regarding the crossroads of the future, they proposed a new concept based on trajectories. With the development of autopilot technology, V2V and V2X technologies have become increasingly popular, and vehicle-to-vehicle vehicles can also communicate location information with each other. This new concept places more emphasis on the location of each vehicle than on the flow of traffic. In their proposed concept, the relationship between cars and cars, cars and transport facilities is more like traffic control in modern civil aviation systems. When the car approaches the intersection, the car will automatically send a “Request to Pass†signal to the intersection’s traffic management system. Each car will be given a “time†and “location†to enter the intersection. According to them, this mode of passage will greatly increase traffic efficiency and avoid many stop-and-go situations. In addition, this type of intersection approach also handles the relationship between pedestrians, cyclists and motor vehicles. In essence, the increase in traffic efficiency is not because the car is faster. But because of relying on V2V, V2X technology, vehicles will pass at a "moderate" speed. Thinking outside the traffic lights MIT's report is to establish a mathematical model through theoretical calculations. Of course, there is an important premise that auto-driving cars are "enough". Last year, Gartner made a prediction: By 2020, there will be 250 million vehicles with networking function in the world. The increasing number of self-driving cars will lead to problems that we have not considered before: Will our existing transportation system also apply to self-driving cars? In GeekCar's previous article, he also mentioned that the number of self-driving cars has increased, it will act in the opposite direction on "urban planning," reduce the number of parking lots, and even bring about human rights issues. In some movies, we often see hackers invade the traffic system to help teammates escape smoothly. When more and more transport facilities are networked and the “automation†of the transport system reaches a certain level, the issue of network security becomes even more important. If the intersection command system fails or is invaded, it will bring great security risks. The law will also become another area that is driven to change. Automated vehicles are put into commercial use, and humans have given the initiative to the machine. The division of responsibility for accidents needs to be reconsidered. For example, in the case of canceled traffic lights, how to determine whether a car is illegal? In the event of an accident, should the responsibility of the command system be taken into consideration? At present, there have been cases in which the impact of autonomous driving technology on the law has taken place. For example, the relevant regulations for self-driving cars in California are tested. The disappearance of the traffic light is only one of the brain holes that people open to the future traffic system. When autopilot technology is popularized, more "games" will be derived.

Places that buy scrap metal will not buy wire if the insulation is still attached.

This is because they want to melt it down right away so it can be quickly sold.
The insulation gets in the way of this process and cannot be melted down along with the wire.
An automatic scrap wire stripper can help you strip the insulation from the wire very quickly and easily.
In the driverless era, is the traffic light to be laid off?
