“…Several studies indicate that RP can be useful for individuals with disabilities or the elderly. Most of them are dedicated to RP for wheelchair users formulated: (1) in a graph-based approach [34] employing a greedy algorithm, Floyd-Warshall algorithm [35], to minimize the average shortest path length by selecting the nearly best shortcut edges to be inserted in the refined graph; (2) in a bottom-up graph approach [36] with integrated geographic information system (GIS) maps; and (3) in a framework incorporating a data model for both indoor and outdoor accessibility, based on modified Dijkstra algorithm [37]. In [38], a working prototype for a mobile RP for people aging with mobility disabilities was presented.…”

Route planning (RP) enables individuals to navigate in unfamiliar environments. Current RP methodologies generate routes that optimize criteria relevant to the traveling distance or time, whereas most of them do not consider personal preferences or needs. Also, most of the current smart wearable assistive navigation systems offer limited support to individuals with disabilities by providing obstacle avoidance instructions, but often neglecting their special requirements with respect to the route quality. Motivated by the mobility needs of such individuals, this study proposes a novel RP framework for assistive navigation that copes these open issues. The framework is based on a novel mixed 0–1 integer nonlinear programming model for solving the RP problem with constraints originating from the needs of individuals with disabilities; unlike previous models, it minimizes: (1) the collision risk with obstacles within a path by prioritizing the safer paths; (2) the walking time; (3) the number of turns by constructing smooth paths, and (4) the loss of cultural interest by penalizing multiple crossovers of the same paths, while satisfying user preferences, such as points of interest to visit and a desired tour duration. The proposed framework is applied for the development of a system module for safe navigation of visually impaired individuals (VIIs) in outdoor cultural spaces. The module is evaluated in a variety of navigation scenarios with different parameters. The results demonstrate the comparative advantage of our RP model over relevant state-of-the-art models, by generating safer and more convenient routes for the VIIs.

“…A pesquisa de Kozievitch et al (2016), preocupa-se com problemas de rotas e acessibilidade de cadeirantes, no qual é proposto uma metodologia, utilizando dados abertos, de melhores rotas para os cadeirantes. Os autores citam que existe uma falta de informações sobre acessibilidade em espaços urbanos, e que isso contribui para que a maioria dos estudos sobre rotas acessíveis estão restritos a cidades ou distritos.…”

“…O método descrito no artigo de Kozievitch et al (2016) utiliza mapas de base para criar mapas derivados com informações mais detalhadas, rotas, rampas, obstruções, para auxiliar nas decisões de locomoção. O estudo de caso foi aplicado na cidade de Curitiba / PR, utilizando aquisição de dados do Instituto de Pesquisa e Planejamento Urbano de Curitiba, e do OpenStreetMap.…”

O turismo acessível permite que as pessoas com deficiência atuem de forma independente e com dignidade em ambientes turísticos. Um Sistema de Informação Geográfica (SIG) permite a orientação do turista, fornecendo mapas digitais navegáveis, possibilitando a pesquisa e busca de informações de locais turísticos, bem como o conhecimento prévio da acessibilidade destes locais. A partir deste contexto, o artigo tem por objetivo apresentar uma análise de artigos científicos relacionados ao SIG para o turista deficiente e um levantamento de aplicativos existentes que ofereçam tal serviço. A pesquisa traz duas contribuições para este cenário: a primeira contribuição é a análise de como está sendo tratado o tema em relação à publicação de artigos científicos descrevendo as características dos trabalhos; a segunda contribuição é o levantamento de aplicativos existentes que podem auxiliar as pessoas com deficiência no turismo.

Platforms like Google Maps or Bing Maps are used by a large number of users to find the shortest path to their destinations. While these services mainly focus on supporting drivers and pedestrians, first services exist that support wheelchair users. Routing algorithms for wheelchair users try to avoid obstacles like stairs or bollards and optimize on criteria like surface properties and slope of the route. In this study, we undertake the first controlled examination of wheelchair routing approaches. By analyzing three routing platforms, including two wheelchair routing algorithms and three pedestrian routing algorithms, across fifteen major cities in Germany, our results highlight that the routes for wheelchair users are significantly longer and partially also more complex than those for pedestrians. In addition, we show that today's pedestrian routing algorithms also output very diverse routes.
