There is a roundabout collapsing access to Granada. The City Council wants to fix it by putting the traffic lights

Spain is A country of roundabouts. And although they are born to relieve traffic circulation, it is common manage to generate the opposite effect. This is the case of the roundabout that joins the highway of the GR-30 Circunvalación with Fernando de los Ríos Avenue, in Granada. A quite complex point of union between key points of the city such as the highway itself, the Nevada shopping center, the hospitals area and several of the most inhabited peoples of the city. This point, located in the municipality of Armilla, will be the second in Spain to incorporate traffic lights with artificial intelligence. Its objective is clear: replace the work of the Local Police for hours. The Rotunda del Chaos. Imagine a roundabout that joins the main highway of your city with the most busy shopping center of it, the university access zone, one of the main hospitals (not only of the city of Granada, but of the surrounding villages), and the main towns of the city. Insured chaos. This roundabout, located at the foot of the GR-30 highway, is famous for the amount of traffic jams that are generated at peak hours, from morning to the afternoon. It is usual to find local police officers regulating traffic at critical moments of the day, but now the City of Armilla wants to go one step further. Traffic lights with AI. The mayor of the town of Armilla, Loli Cañavate, explains to Granadahoy That the implementation of traffic lights with artificial intelligence is scheduled to replace the work of these mobility agents during tips. How will it work. The traffic light system will allow them Adapt in real time to vehicle flow. How will they do it? First, several traffic lights will be installed at the different access points to the roundabout. A total of five tickets distributed in the GR-30 descent, the departure of the Albán Park area, the departure of Fernando de los Ríos Avenue in the Granada direction, the departure from the Health Technology Park and the departure of Fernando de los Ríos Avenue Direction Armilla. The traffic camera system will collect updated information about traffic, and this data will be used so that traffic lights can regulate the circulation opening and closing the tickets to the roundabout according to the congestion zones. A little step towards the inevitable. The case of Granada is particular, since this roundabout will end up in a underground process to completely avoid this decongestion. However, the implementation of smart traffic lights begins to gain more and more strength. Neighboring countries, such as Germany, They started with pilot tests More than two years ago. The result? An improvement between 10 and 15% in the fluidity of traffic, with a scheduled improvement margin up to 30%. Without going as far, in cities like Córdoba There are already traffic lights with artificial intelligencealthough in this case with a system aimed at that pedestrians with reduced mobility can cross more easily. Specifically, if the traffic light detects that we have mobility problems, it is open for a longer time. In Xataka | Spanish traffic lights are more dangerous than the rest for a peculiarity.

There are people putting toilet paper in the fridge. What does science say about the trick to eliminate bad odors

If one day we open our fridge and encounter A roll of toilet paper insidewe might think that we live with a very clueless person who has confused the fridge with the bathroom closet. We would probably be wrong: There is a reason To put toilet paper in the fridge. The question is whether it is a good idea. The first question that comes to mind is: why? What is sought with this strange idea is to reduce the bad odors that are sometimes presented in our fridge. The “trick” also promises to extend the life of our food and even save energy consumption. Ok and work? Although we have not tested the method, the toilet paper could help us Eliminate bad odors from our fridge. Although there are some issues to consider to go for our paper rolls. The logic behind is that the toilet paper can absorb moisture (this paper is absorbent so it is capable of collecting environmental humidity by dehumidifier) ​​and with it the bad smell of our fridge. It would also help to preserve food better, reducing the rhythm to which they spoil and avoid passing that emit new bad odors. Insert paper into the fridge is one of the “tricks” that he proposes The Food Security Service of the United States Department of Agriculture (USDA), but not as a way of maintenance but as a way of ending persistent odors in our fridge. In an article dedicated to how to eliminate bad odors from the fridge, the service suggests filling our fridge of Rolled newspaperthen close the door and leave it like this for several days. After taking out the paper, they recommend cleaning the fridge with water and vinegar. Using newspaper has the advantage that this will be a role that will be discarded equally, but it is also an increasingly weird paper to find in our homes. If we use toilet paper we must avoid using paper that we have had stored in the bathroom outside its wrapping since it will have been accumulating moisture and will be more “loaded” from it. Avoiding bad odors It should be noted that the use of paper, whether newspaper or hygienic, is not the first method suggested by the USDA on its page as a way to eliminate bad odors from our fridge. The first thing to do in these cases is to eliminate any food spoiled that could be causing bad smell. Then, remove all the trays and drawers from the fridge and clean them with soap and water. Then we can give them a bath with a “sanitary solution” making a tablespoon of bleach not aromatized in 3.5 liters of water. Also use this solution to clean the interior of the fridge. After that we must leave the appliance open for a quarter of an hour. Appliances manufacturers are also A good source of information when looking for tricks that allow us to improve our use of the devices that manufacture. These methods include several cleaning products, we must be aware of Do not mix them. For example, mixing bicarbonate and vinegar will cause the different levels of acidity of the products to be annulled since vinegar is acid, while bicarbonate is a base. Mix vinegar and bleach, on the other hand, It is a risk to our health since the mixture will release harmful gases. Interestingly, this “trick” could help us save energy. Every time we open the door of the fridge we can generate air currents that introduce warm air from abroad into the fridge. When we close the door, the fridge must renounce this air, spending more energy. The more full the fridge is, the less air it can be exchanged with the outside, so a fridge fills less energy. If we put a roll of toilet paper (as if we put a brick), the fridge will cool it once alone, and not as many times as we open and close the door. This “trick” can be useful in very specific contexts, if for example we have our refrigerator halfway fill more or less constantly.
