The system aims to prevent traffic accidents and reduce the costs associated with providing initial care to people who are injured at intersections due to carelessness or improper use of mobile technology. • PREVIOUS ART Today we encounter technological pedestrians or passersby who, because they are engrossed in the use of their cell phones, cross a street without looking, bump into other people, trees or light poles and often do not even flinch at the warnings of horns or other pedestrians. Pedestrian behavior related to the use of portable technology, especially cell phones, influences accidents. This occurs when pedestrians suddenly enter the roadway or cross streets in unauthorized areas without using crosswalks, often due to distractions such as using a cell phone app or listening to music with headphones. Drivers also contribute to increased accident statistics through distractions, poor visibility, or speeding. 1449275 of 24 Due to all these problems, different systems appear that actively or passively tend to protect pedestrians, preventing accidents from happening or trying to mitigate their consequences. Technological pedestrians are those people who use any mobile device (1) in public, whether to talk, make a video call or listen to music, for example. The multitude of applications and uses that can be used today on a cell phone (1), cause its massive and constant use, making people able to walk with their eyes glued to the cell phone screen, abstracted from what is happening around them or to walk paying attention only to the loud music they listen to through the headphones for example, which prevents them from hearing the noises of the environment that surrounds them, which on many occasions and unintentionally leads them to situations of extreme danger. These are just two of the most frequent distracting uses of a cell phone, but there are countless other apps and uses, such as email, chat, video games, movies, internet browsing, and so on, that are readily available to transport a person to another reality and distract them from their surroundings. The real danger lies in losing awareness of the risks associated with using a cell phone app while walking in public. The publication of patent document AR029042 B1 is known, disclosing a pedestrian / vehicular traffic light that connects to the main controller to activate a light element via a microcontroller. This microcontroller selectively activates all of the LEDs or only those configured sequentially in a countdown. These latter LEDs indicate the time remaining before the traffic light changes from green to green. This countdown The 1449275 of 24 regressive presents a novelty with respect to other known systems, by visibly warning of the lapses in a known unit of time, regardless of the duration of each cycle of enabling and cutting the traffic light, which represents a cautionary signal capable of preventing accidents. It is also known in document ES1034252-U, where a road sign is described consisting of an angled mast with a luminous traffic canopy over the pedestrian path that incorporates spotlights on its lower face directed towards the pavement to improve the visibility conditions of drivers and pedestrians, powered entirely through the electrical supply. In document ES1060684-U, a section of road signage raised above the level of the roadway in the shape of a trapezoidal bump is detailed, containing passive luminous elements such as small bulbs, LEDs or fiber optics that adjust the day / night lighting by means of ambient light sensors. Document ES1067629-U describes a pedestrian crossing indicator device consisting of a traffic light signal on a vertical mast embedded in the ground and a horizontal light strip across the roadway, preferably using LEDs. The mast is equipped with short- and long-range optical sensors to detect the presence of pedestrians and vehicles, respectively. Document ES2311398-A1 describes an electrical installation with several photoelectric emitters / receivers placed on the sidewalk using fixed vertical supports that detect the presence of pedestrians preparing to cross the road and activate luminous terminals located in the 1449275 of 24 periphery of the pedestrian path and vertical light signs located on the sidewalk. In document ES2321794-A1, a section of overpass above the road level is described, in the form of a trapezoidal bump, where the road signage is made up of electro-luminous diodes that are activated by detecting the presence of pedestrians in pressure zones located at the entrances. Through the invention described in DE202004006444, a device is disclosed with the objective of protecting pedestrian paths, thanks to markers located on the sidewalks, where said device contains sensors for the presence of pedestrians and vehicles that activate the warning lights in case of detection. US patent 7,317,405 B2 details a pedestrian crossing alert system (AS) consisting of a mast on the sidewalk with flashing lights, including solar cells on the mast for power, wireless communication for synchronizing the signal with the opposite mast, and a mechanical switch activated by the pedestrian. Many prior art devices employ a presence sensor located on the sidewalk, typically mounted on vertical traffic signs, which detects the pedestrian crossing, and a set of LEDs located on the roadway that are activated by a presence sensor. The problem identified is the distraction, loss of attention, or abstraction that pedestrians carrying cell phones experience through direct observation of the screen while walking in public. This makes it imperative to develop a system that allows for intervention to ensure that 1449275 of 24 so that the pedestrian can regain the necessary attention in a risky situation on the public road, such as when one approaches the pedestrian path to cross a roadway. The statistics are worrying. The data collected indicates that 21% of pedestrians who use their cell phones while walking demonstrate a lack of respect for both traffic lights and crosswalks. 50% of them only respect one of these, and only 29% respect both. In Buenos Aires, Argentina, 44% of traffic fatalities are pedestrians. In Bogotá, Colombia, the figure is 60%. In Mexico, it's 70%. Across the European Union, the average is 40%. In Spain, 80% of pedestrians admit to using WhatsApp while crossing the street. According to the report by the British Medical Journal and the Mapfre Foundation, “98% of accidents (in which the pedestrian is responsible) involved pedestrians using their cell phones.” The main objective is to reduce road accidents, safeguard the lives of pedestrians and reduce the costs derived from primary care of injured pedestrians (legal costs and lawsuits against the state already private) when crossing intersections due to carelessness or incorrect use of cell phone technology, that is, to be able to achieve technological pedestrians, safe in real time. Looking at a cell phone, answering a message, making video calls, using social media, and watching videos are the most common behaviors people exhibit when using a smartphone. It's important for pedestrians to recognize that they are also part of the urban traffic, and indeed, the most vulnerable of all those interacting in public spaces. For this reason, it's crucial that pedestrians and those who are tech-savvy are able to regain control of the moment whenever they use their cell phones in public. • BRIEF DESCRIPTION OF THE FIGURES 1449275 of 24 Figure 1 is a representation of the pedestrian crossing (SP) and the entire environment where technological pedestrians or passersby move with a basic coverage scheme and arrangement of sensors (2), emitters (9) and receivers (10) of electromagnetic radio frequency signals and others, which make up the safe corridor (S) and the coverage area of ​​the Alert System (SA) to technological pedestrians or passersby, for the prevention of road accidents. The detection is detailed more precisely through technological implements such as RFID radio frequency antennas (9), Bluetooth signal transmitting devices or modules (Bluetooth BLE Beacons or similar) (4, 11), Bluetooth signal receivers (dongles and / or receiving devices that fulfill the same functionality) (5), modules composed of a Bluetooth emitter / receiver and a PIC microcontroller or programmable integrated circuit (19) and those analogous to those that fulfill the same purpose of referencing the traffic light or controller and allowing interaction with the Application / System present in the mobile device or smartphone), wireless Wi-Fi network signal radiation antennas or similar in Hotspot mode (6), bearing in mind that the capture, transmission and exchange of data and / or information through cellular networks also intervene in the described area (7),whether for development or management with the mobile or cellular devices themselves (which in turn have the possibility of managing and exchanging data through the network or wifi link set up on site for this purpose (6)), as well as the exchange of information and data with complementary sensors and / or actuators classified within the wide variety of IoT (3) (Internet of Things: internet of objects)., Within the safe area (S), near the pedestrian crossings (SP), the possibility of adding pressure or contact sensors for activation by applying a force to them (2) is considered, complementation with facial recognition cameras or another with artificial intelligence capable of recognizing the human figure (12) and predicting its advance on the pedestrian path (SP); inductive sensors, sensors 7 1449275 of 24 ultrasonic, infrared, optical, laser, and field sensors (2) and other sensors that allow the correct positioning and unambiguous identification of the pedestrian or technological passerby. The objective to be determined in the safe corridors or paths (S) is based on existing technology, including the possible creation of proprietary protocols, artificial intelligence and the use of different types of own or third-party networks, as well as the allocation of communication or link frequency licenses in order to use or develop secure and efficient channels for sending crossing alerts. Figure 2 shows a complete general scheme of the entire proposed Alert System (AS), where complementary and / or supplementary alternatives to the technological pedestrian or passerby detection system are identified. The interconnection scheme is noteworthy, utilizing Bluetooth signal emitters, Bluetooth Low Energy (BLE) beacons, and similar devices (4), with the mobile device (1) itself acting as the emitter and beacon. Bluetooth BLE or similar signal receivers (5), such as dongles or similar devices, are also included, with the mobile device (1) acting as the receiver. Furthermore, the use of modules or interfaces composed of antennas or Bluetooth transmitter / receiver devices, along with microcontrollers or programmable integrated circuits (PICs) (19) and / or similar devices, is highlighted. These microcontrollers perform the same function, enabling the synchronization of traffic light actions regardless of whether the traffic light is integrated into a centralized traffic control network.In turn, mention is made of identification through RFID tag readers and the supporting infrastructure, links via Wi-Fi, LAN, WAN, LPWAN, LoRa and / or other similar network signals (6, 16, 17, 18), links with cell phone provider antennas (7), detailing the types of access possible to reach the data / Internet connection necessary to access the database and the control system. Detection through the use of GPS global positioning is indicated (8), this and the other devices or 8. 1449275 of the 24 technologies mentioned are part of the solutions that support the system for triangulation and determining the position of the mobile device and its user. The other components of the proposed architecture are also observed. Additionally, facial and / or physical person recognition detection is mentioned as an accessory, as well as the complementarity of any other type of supplementary or complementary sensor, such as pressure, contact, infrared, inductive, ultrasonic, optical, laser, field sensor, and other sensors in general that allow for the zoning and individualization of the subject. These sensors may belong to the field of IoT (Internet of Things) technology or may not. -In Figure 3, the Pedestrian Alert System (SA) is shown, which displays the location of the Bluetooth signal emitting devices (low signal Bluetooth beacons BLE and / or analog) (4), and the Bluetooth BLE or analog signal receiver(s) (dongles or similar) (5) on a traffic light pole (PSE). This allows mobile devices or cell phones (1) within the range to act as Bluetooth signal receivers and / or emitters, connecting with the system and each other to enable referencing through their peer, thus extending the range and accuracy of the system.Similarly, replacing and / or complementing the above, there are interfaces or modules composed of a Bluetooth transmitter / receiver and a microcontroller or programmable integrated circuit pic (19) and those analogous that fulfill the same purpose, allowing interaction and referencing between the mobile device(s) that make up the Alert System and the traffic light or controller. Also indicated are the location of the access points or wifi access points (6) with their corresponding Gateway router (16) that make up the wifi signal network (which enables the exchange of communication data through the mobile device application (1), the global positioning links (8) and connection with the cellular network (7), as well as the location reference of complementary identification sensors (2, 3). 1449275 of 24 - Figure 4 shows the Pedestrian Alert System (PA) (RFID + accessories) with the location of the RFID antennas (9) on the safe path (S), near the pedestrian crossing (SP), and on the traffic light pole (PSE), as well as its connection to the positioning and data exchange systems (7) via Wi-Fi (6) and cellular data network (7). The image also indicates the location of complementary sensors (2, 3) for positioning the pedestrian. Figure 5 shows a simplified operating scheme for Bluetooth signal emitting devices (low-band Bluetooth beacons and similar devices) (4), receivers, Bluetooth BLE or similar signal receivers (dongles or similar devices) (5), an interface or module composed of a Bluetooth emitter / receiver and a microcontroller or programmable integrated circuit (PIC) (19) and similar devices that serve the same purpose, detection, information exchange between the mobile device (1) and the servers and database (DIn, SCVD), data management, and subsequent system action by sending an alert signal to the distracted pedestrian's cell phone. Communication can be established through the mobile phone network (7) or through the Wi-Fi access network (6) to access the cloud / Internet and from there reach the database to validate the user and obtain the interference response for the distracted user.The use of interfaces or modules composed of a Bluetooth transmitter / receiver and a microcontroller or programmable integrated circuit (PIC or similar) (19) allows referencing the controller or traffic light and interaction with the application on the mobile device, totally or partially dispensing with communication with central servers in case of communication failure or when the traffic light or crossing has controllers that are not integrated into the central traffic monitoring network or these present technological conditions or limitations, thus allowing the Alert System (AS) to continue operating and fulfilling its safeguarding purpose. 1449275 of 24 • DETAILED DESCRIPTION OF THE INVENTION References are provided for the various components involved in the alarm system (AS), these are: SA.

Interface or module composed of a Bluetooth transmitter / receiver and a microcontroller or programmable integrated circuit (PIC and similar) The problem is solved through the implementation of an Alert System (AS), which will drastically reduce accidents involving pedestrians, with the consequent less intervention of health emergency systems, security forces and / or traffic controllers, also avoiding the delays caused by traffic closures after an accident has occurred. To this end, the proposed Alert System (AS) is based on the detection of the pedestrian or passerby walking along a sidewalk on the public road, when he is heading to cross the pedestrian path (SP) by walking through the safe path (S), in the direction of the detection zone, located near the corner where the system monitors the circulation of pedestrians through different technological implements. 1449275 of 24 According to the alternatives adopted, the technological means that support the solution of this Alert System (AS) are: Gateway routers (16) of wifi network (6), interconnected with each other and with the servers through the cloud (DIn), in order to create a coverage zone or Hotspot (6), bluetooth signal emitters (4), low signal bluetooth beacons (BLE) and analogous devices, the mobile or cellular device itself being able to behave as such fulfilling said function; bluetooth BLE or analog signal receivers which may be dongles or similar devices (4) and the mobile or cellular device itself acting as a receiver, interfaces or modules composed of bluetooth emitter / receiver and microcontroller or programmable integrated circuit pic (19) and those analogous devices that fulfill the same purpose, allowing the interaction between the mobile device(s) and the traffic light or controller, RFID technology radio frequency antennas (9) and the support infrastructure (6, 7),The smartphone, in turn, and its ability to establish data exchange connections via the cellular network (7) or the WiFi access network (6), allows communication between the mobile device and the server (hosted locally or in the cloud) (DIn), which contains the database and processing algorithm. This enables the verification and validation of user data and the generation of the alert response that will appear on the passerby's mobile device screen. Also noteworthy among the technological resources supporting the proposal are the mobile device's internal sensors (1), including the GPS global positioning sensor, gyroscope, accelerometer, hall sensor or magnetometer, capacitive sensors, ambient light sensor, and proximity or active screen sensor, as well as its identification address or MAC address.important for the unambiguous identification of the device and its belonging to the validated registered user. Other technological means considered, referred to as external and complementary, are pressure or contact sensors for activation by applying a force to them (2), facial recognition cameras (12) or another with artificial intelligence capable of recognizing the human figure and predicting its movement on the pedestrian path (SP); inductive sensors, ultrasonic sensors, infrared sensors, optical sensors, laser sensors, 1449275 of 24 field sensors and other sensors (2) that allow the correct positioning and unambiguous identification of the pedestrian or technological passerby, these may belong to the field of IoT (Internet of Things) technology (3) or lack this technology. The partial scheme of the Alert System (AS) in the vicinity of the pedestrian crossing (SC) can be observed in detail in Figure 1. The general detailed scheme of the Alert System (AS) is observed in Figure 2. Through Wi-Fi hotspots or zones (6), the mobile device's GPS sensor (8), and / or cellular cell positioning (7), the Alert System (AS) allows for pedestrian approximation, recognizing and segmenting the area of ​​operation based on their location. Furthermore, since the mobile device application can store previously downloaded information on the location of intersections, corners, or paths with alert coverage, the pedestrian's location is segmented for more precise subsequent detection. As the pedestrian approaches the safe zone (S), in front of the pedestrian path, a more precise detection is carried out which will initiate the process of interaction and determination of the action to be developed with the cell phone or mobile device (1) of the pedestrian. Upon receiving the activation signal, the cell phone or smartphone device (1) compares this information with that of fixed or proximity positions, included in the application / System to subsequently, if applicable, send information to the servers where it is analyzed, generating the return of a specific response signal for that device. The Alert System (AS) detects the pedestrian's intention to begin crossing as the pedestrian walks along the safe path (S) and approaches the safe detection zone. This is where the system architecture (low-signal Bluetooth (BLE) transmitters and receivers (4, 5), interfaces or modules composed of a Bluetooth transmitter / receiver and a microcontroller or programmable integrated circuit (PIC or similar) (19), and / or RFID antennas (9) 1449275 of 24 Gateway routers (16) of wifi network (6), cellular networks (7) and other complementary external sensors (2), including nearby mobile devices belonging to the System in a broader sense) detect the pedestrian so that the Alert System (AS) programming then performs a sampling of the different smartphone sensors, focusing especially on the data from the accelerometer, gyroscope, ambient light sensor, proximity sensor or active screen, hall sensor or magnetometer, capacitive sensors, gps sensor, bluetooth and wifi, among others, to locate the exact position and direction of the pedestrian, their proximity to the pedestrian crossing (SP) and the intention or predisposition to initiate a crossing or advance and their visualization or interaction with the mobile device or smartphone (1). It is important to note that the Alert System (AS) response will appear in full screen mode (or similar) on the cell phone screen, thus becoming an active and real-time traffic signal, making the traffic signal not only "visible" but "seen". With this inventiveness we managed to install traffic signs WHERE THE PEDESTRIAN'S EYE IS FOCUSED AT THE MOMENT OF DANGER, achieving 100% effectiveness in protecting the lives of pedestrians distracted by their cell phones, or technological pedestrians. In case of technological impediments and / or restrictive policies of the various mobile device operating systems, the alert will be a pop-up visual notification with vibration and / or an audible signal for the same safety purpose. Through the governance deployed by the system, the application seeks to block access to all pop-up notifications (including those from social media applications, emails, and even the pedestrian's own address book). Through the artificial intelligence present in the system's programming architecture, other alerts from the networks are retained and managed, and then released accordingly. 1449275 of 24 automatically once the pedestrian leaves the protection zone after the safe crossing has been made. It should be clarified that for the Alert System (AS) to work, it is necessary that the smartphone (1) has the application installed natively or that the user voluntarily downloads the application to the cell phone. After activation and acceptance of the necessary legal conditions, the application runs in the background, acting automatically once a pedestrian is detected approaching a crosswalk. The system compares their position with the information provided about crossings or safe zones (S), included within the downloaded application, using information that can be provided by the Bluetooth transmitter / receiver interface or module and the microcontroller or programmable integrated circuit (19), as applicable. It uses information from the cellular network (7) and the available Wi-Fi access network (6) to access the data network (7) and the internet, which in turn allows it to access the Alert System (SA) server and database to validate the pedestrian's user (Din).The software sends an audio-visual and vibratory alert signal as a response, which appears on the full-screen display of a cell phone or similar device, replicating the "state" of the pedestrian traffic light in real time. It is capable of communicating each of these states (red and / or white silhouette of a person) and indicating the amount of time available (countdown) to safely cross the pedestrian crossing (SP), or another signal with the same purpose. Figures 3 and 4 show the replication of the ten remaining seconds for each traffic light pole (PSE) on the screen of the cell phone or mobile device (1), indicating the time remaining to safely cross. While the Alert System (AS), as a proposed solution, is intended as a system to assist pedestrians on public roads, its implementation is initially focused on use at traffic lights (TS) or intersections. 1449275 of 24 pedestrian crossing (SP), its application is broader considering all public transport, adapting to the stations or arrival platforms of subways and trains, level crossings of the same, bus stops and / or metrobus platforms or similar, including the possibility of adapting the technological implements and the platform of this Alert System (SA) for the regulation of parking on public roads and traffic management. Data processing and access via the cloud (DIn) provide the proposed solution with the ability to manage information related to traffic flow and concurrency mapping for efficient management of crossings and arrivals of mobile units under an integral concept that we will call “SAFEWALK”. In this way, SAFEWALK aims to become a true digitalization of traffic signals in a safe manner, preserving the integrity of pedestrians and the order of traffic and movement within the city. Given the wide variety of traffic lights and traffic control systems in Argentina, two general governing systems are proposed for their interaction. For those systems with mechanical, electromechanical, and electrical controllers not connected to the central traffic control center, a local unit will be installed near the local controller to trigger the Alert System (AS). This unit can obtain the countdown timer or activation signal locally via a system-to-system interface or through an interface / device that collects information from the cloud (DIn) or a dedicated computer server (SCVD). The second, decentralized alternative gathers alert information or pedestrian crossing signal switching and / or activation times from a remote central data controller or cloud server.Both technologies or implements can coexist within the universe of an Alert System (AS) called SAFEWALK. 1449275 of 24 The use of the networks or communication channels mentioned can be visualized in Figure 2, which details the four main communication channels that support the proposed solution. This Alert System (AS) and pedestrian assistance system (PS) can be detected through RFID antennas (9) (detailed in red), or it can be positioned through Bluetooth Low Energy (BLE) signal emitting devices (Bluetooth beacons or similar) (4), or by the device acting as an emitter (11) and the system having Bluetooth receivers (dongles or similar) (5), and / or through the use of interfaces or modules composed of a Bluetooth emitter / receiver and a microcontroller or programmable integrated circuit or similar (19) (detailed in green).accessing the system server and database (DIn) through the cellular network (7) (network detail in blue) or a fourth instance where the system complements the previous ones and interacts through wifi networks (6) (network detail in yellow) (which can be interconnected between each alert station to increase the range and synergy of the SYSTEM), where the routers communicate remotely to the central data / Internet (DIn), in order to validate a pedestrian or technological passerby in danger, perform the governance of calls and / or notifications and generate the response of the Alert System (AS), which warns of the danger, at a street crossing on the public road. Power Supply The module or interface device(s), such as a Bluetooth signal transmitter / receiver and a microcontroller or programmable integrated circuit (19) and / or similar devices that allow the addition of messages or communication between devices and traffic light controllers or the traffic light itself, will be able to obtain power (electrical energy) for their operation through different alternatives depending on the degree or complexity of obtaining a safe power supply. Consequently, the possibility of connecting to the traffic light or controller itself is differentiated (both for the use of a trigger or firing signal or optical, digital, or other reference signal, as well as for 18 1449275 of 24 voltage and current necessary to power the logic or electronic interface). Another alternative that provides autonomy, safety, and distinctive eco-environmental characteristics is the use of solar panels and storage batteries to power the described logic or interface. In the case of traffic light controllers connected to the transit network, it will be possible, where applicable, to power them through energy supplied via PoE (Power over Ethernet) and / or similar connections. Finally, the devices described above will have backup batteries of varying capacity according to the needs of each intersection or controller to which the traffic light being modified by the solution or invention may or may not be connected. Concept of Integrality of Inventiveness The inventiveness of the proposed solution lies not in each device but in the integration and combination of each and every one of the devices or subsystems present (both the external physical architecture and the intelligence within the Smartphone that manages its various components described above), achieving global governance and interaction and their joint work in such a way as to cover different contingency scenarios, even in the face of a lack of communication in the data frame, doing all this in real time, which makes the Solution / System a true and effective real-time traffic alert. Hotspot detection system, Wi-Fi router, network By establishing a Wi-Fi signal coverage zone (Hotspot) (6), devices belonging to or connected to this network can be uniquely identified through identifiers such as MAC addresses (6). In this way, and through triangulation, the device is positioned at a specific point or physical region. Complementarity with the other components of the Network or System, in a broader sense, allows for a reduction in the margin of error in location. With this methodology and understanding the case 1449275 of 24 in which the mobile device (1) may be reduced in its connection capacity to the data network (7), it is the system through its own network that would carry out the management of data and sending of signal to the device through this same way, understanding in turn that the application has information of fixed locations that allow it to check the positions of passersby, even in the fortuitous case of losing connection with the central database or when access to it is limited, for some reason. Another alternative to the Wifi Hotspot network (6) is the support and exchange of data but with validation and / or exchange of the same through the frame or network of cellular telephone providers (7). Both this system and those mentioned below are complemented by the use of location technologies through GPS global positioning signal (8), triangulation by antennas through mobile phone cells (7), among others, in addition to the use of the internal sensors of the mobile device (1) and the complementary sensors (2), belonging or not to the world of IoT technology (3) and its corresponding communication that was mentioned throughout the document. RFID detection system Radio frequency identification and detection or RFID is a remote data storage and retrieval system that uses an RFID signal transmitter / receiver reader or antenna (9, 10) and devices called tags (RFID TAG) that are attached to objects, allowing their identification through the use of radio waves. The use of RFID technology requires the prior distribution of RFID tags, which must be attached to the mobile device for the correct reading of the pedestrian's position (14). 1449275 of 24 This system obtains pedestrian position information when the transmitting antenna (9), located on the traffic light pole (PSE) or on the ground as shown in Figure 1, or the RFID readers (10), also located on the traffic light poles as shown in Figure 4, detect the presence of an RFID tag. Detection occurs when a pedestrian using their cell phone passes through the magnetic field generated by the RFID reader's transmitting antenna, inducing a current through the loop containing the tag on the phone. This current powers the microchip and memory stored in the RFID tag, enabling the RFID processing system (15) to interact with the database and identify the pedestrian. Once the RFID TAG information is captured, the data processing subsystem (15) interacts with the Alert System (AS) computer platform, which will determine the events to be executed based on the behavior adopted by the pedestrian user. The components of an RFID system are: • RFID tag (RFID tag), is placed on the mobile device (1). • RFID Reader or Transmitter / Receiver Antenna (RFID READER) (9) • Data processing subsystem or RFID middleware (15) The implementation of this solution will be through the installation of an antenna mounted on the traffic light (SE), as shown in Figures 1 and 4, or aerially, as shown in Figure 1. Shorter range antennas or readers (9) will also be placed on the roadway, covering the full width of the sidewalk before reaching the corners, indicated in white in Figure 1 or in yellow in Figure 4 on the safe path (S). This alternative with RFID reader detection contemplates, as previously described, the storage within the mobile device of fixed reference positions of pedestrian crossings and other signage, as well as complementarity with external and internal sensors of the mobile device itself, 21 1449275 of 24 as well as the possibility of linking and exchanging data through the mobile phone provider (7) or the wifi network (6) located in the vicinity of a pedestrian crossing (SP). Detection system with Bluetooth Low Energy signal emitter / receiver devices Beacons or electronic beacons are transmitting devices used to radiate Bluetooth Low Energy (BLE) signals (4) to nearby mobile devices without the need for prior synchronization. When the signal emitted by these beacons, bluetooth beacons or analog signal emitters (4) is captured by the Smartphone (1), it is possible to execute real-time actions aimed at preserving the integrity of the pedestrian. The presented system triangulates information through unambiguous identifiers such as the MAC address, positioning the pedestrian at the correct point before triggering the process that activates the sending of the alert signal when the pedestrian approaches the pedestrian path (SP) to make the safe street crossing. A differentiating factor of this technology is the low level of signal emission used, which translates into lower battery consumption of the mobile device or smartphone by the user. In Figures 3 and 5, the location of the Bluetooth signal emitting devices (Bluetooth beacon, BLE or analogous) (4), the Bluetooth signal receivers (dongles or analogous) (5) and / or interfaces or modules composed of a Bluetooth emitter / receiver and a microcontroller or programmable integrated circuit or analogous (19) can be observed, on the traffic light pole (PSE) or they can also be located on the safe path (S), in proximity to the pedestrian path (SP), as shown in Figure 1. An important factor to highlight in this alternative is the possibility that the smartphone or mobile device (1) can act as a Gateway or access portal 1449275 of 24 receiving the signal from the Bluetooth beacon (4) to process it and send it through the data network connection (7), Wi-Fi network (6) or other network to which it is connected or by the mobile device acting as a Bluetooth transmitter (11), Bluetooth beacon or analog (4), to be captured by a Bluetooth signal receiver (dongle or similar) (5) belonging to the system and through a router (16) acting as a Gateway, connected to the Alert System (AS). By using interfaces or modules composed of a Bluetooth transmitter / receiver and a microcontroller or programmable integrated circuit or similar (19), communication with servers can be dispensed with. In this way, in the event of a communication failure with central servers, or when the traffic light or intersection has controllers that are not integrated into the central traffic monitoring network or that present technological limitations or constraints, the Alert System (AS) remains operational, fulfilling its safeguarding purpose. In this way, different communication channels can be used to the data servers (SCVD), and a combination of alternatives and connections between the different pedestrians participating in the network can even be made, in order to expand and improve the positioning information regarding the alerts to be sent through the application, as shown in detail in Figure 2 and Figure 5. In the alternatives described in the invention, both individually and in partial or total combination, a connection is established with the servers (SCVD) through various communication channels to validate user data, the instance, and the user's location, via mobile phone networks (7) or Wi-Fi signal networks (6) designated for this purpose. Once the user, the software, and the architecture of the Alert System (AS) are validated, the system executes the governance action for incoming notifications and / or calls to the device, retaining them and sending the alert signal to the pedestrian, as previously explained, to enable them to safely cross the street. The notifications and / or calls are then released once the pedestrian has successfully crossed the street. 1449275 of 24 It is worth highlighting in this alternative the complementarity with the different detection devices (2, 3, 4, 5, 6, 9, 10, 19) and sensing belonging or not to the IoT (Internet of Things) universe (3), as described throughout the document. 1449275 of 24 20269334240 - - 20269334240 Digitally signed by PORTALTRAM ITES - INPI Date: 2021.07.21 13:43:00 -03:00 Reason: Digitally Signed by the INPI Location: Buenos Aires, Argentina
