Abstract
La idea de este proyecto viene motivada principalmente por los impedimentos que personas con diversidad funcional, ya sea física o cognitiva sufren diariamente al acceder a ciertas infraestructuras sobre las cuales no tienen ninguna referencia previa. Nuestro objetivo es proporcionar una aplicación que permita a estas personas conocer con anticipación si para una infraestructura existe un camino entre dos puntos de su interior, libre de impedimentos físicos como escaleras. Por ese motivo es necesario identificar elementos como rampas de acceso o ascensores que les permitan conocer el nivel de accesibilidad de la propia infraestructura.
La aplicación, que ha sido enfocada sobre el edificio de la facultad de informática de la Universidad Complutense de Madrid, además de resolver el problema mencionado, también es capaz de calcular recorridos mínimos entre dos puntos cualesquiera de su interior. De este modo, cualquier otra persona sin impedimentos funcionales también podría hacer uso de la misma.
El proyecto está fundamentado sobre los sistemas de información geográfica o SIG [3] y se ha desarrollado a través de las siguientes etapas:
1. Geocodificación [4] de todas las áreas del edificio mediante la herramienta de edición de OpenStreetMap [5].
2. Implementación de un algoritmo de vuelta atrás [6] para el cálculo de recorridos mínimos junto con la herramienta OpenTripPlanner [7] para generación de grafos de rutas.
3. Desarrollo web con JavaScript y la librería Leaflet [8] para mostrar al usuario el mapa interactivo de la facultad sobre el que se ejecuta nuestra aplicación.
The project has been motivated by the idea of restrictions that people with disabilities, either physical or cognitive, experience on a daily basis by accessing to different infrastructures on which they don’t have any previous information about. Our purpose is to provide them an application that makes possible to know in advance if there is a free barrier way, such as stairs, between two points from the inside of a building. In order to do that, its necessary to identify elements like ramps or elevators which lets users to know the accessibility level of the infrastructure. The application, which has been focused on the Computer Science building of the Universidad Complutense de Madrid, in addition to solving the previous problem, it’s also able to find shortest paths between any 2 points from the indoor. This way, any other person without functional disabilities could also use the application. The project its based on the geographical Information Systems (GIS) [3] and it has been developed through the following steps: 1. Geocoding [4] with OpenStreetMap [5] editing tool of the whole areas of the building. 2. Deployment of the backtracking algorithm [6] for finding shortest paths along with OpenTripPlanner [7] tool for the routing graphs generation. 3. JavaScript web development together with Leaflet [8] library for displaying users the interactive map of the building.
