In recent years, the demand for air transport has been growing rapidly. In 2014, more than 23 million passengers in the Canary Islands, and almost 2.2 million worldwide, used airports. If current conditions continue, it is projected that by 2020 there will be more than 7 billion passengers worldwide. However, the capacity of current airports will only be able to handle 6 billion of them. This will lead to a shortage of these critical infrastructures, which will ultimately result in greater passenger dissatisfaction if the necessary measures are not taken beforehand to improve their experience and airport operations. The objective of the INSITU project is to develop new technological services that optimize the operations that airport users must carry out in the terminals. It aims to provide intelligent systems capable of leveraging ubiquitous wireless technologies and existing airport infrastructure to, for example, improve wayfinding within the terminals and minimize transit time, since most of that time is spent moving around and/or waiting to be served in person. Therefore, the development of the services proposed in INSITU will allow for a substantial improvement in efficiency thanks to the optimization of waiting time and baggage management, as well as movement within airport spaces. All these services will be passenger-focused, aiming to maximize comfort, reduce waiting times, and provide relevant information. Furthermore, they will facilitate real-time control and monitoring by airport authorities of passenger flow within terminals and baggage location, thereby increasing the security of these critical transport infrastructures. The innovations proposed in INSITU are primarily based on available technologies and current regulatory conditions. In particular, the infrastructure supporting the proposed improvements to airport services, such as check-in, boarding, security screening, baggage claim, etc., will be based on smartphones with the latest communication technologies, such as NFC, Wi-Fi Direct, 4G, Bluetooth Low Energy, etc., as well as sensors and Wi-Fi 2.0 hotspots. The team's experience in several related national projects will be key, especially during the study, design, implementation, and evaluation phases, allowing us to define optimal solutions to the problem presented. The support of the University Institutes IUDR-ULL, IUCTC-ULPGC, and SIANI-ULPGC will also be invaluable. In the final phase, we will conduct a final field test to demonstrate the practical applicability of the results obtained, thanks to the collaboration of Atlantis Tecnología y Sistemas, a company that is part of Binter.
