Abstract
People with mobility impairment must travel through cities with extra care. An intelligent database of Maps for Easy Paths (MEP) project for storing and retrieving accessibility information about a particular path by using PostGIS may enable the public to enjoy the privilege of the technology that alleviates the problem of city accessibility through the Web or, more recently, through smartphones/tablet applications. The methods and techniques for intelligent database to storeand retrieve accessibility information by using a relational intelligent PostGIS database are described. The conceptual data model is designed for an intelligent database (PostGIS). Users will be able to actively participate in the process of taking pictures of obstacles, uploading them to the MEP server and giving some comments on the attributes of the picture of the barrier. The resulting data will help others to locate and evaluate paths. This paper presents the conceptual data model design as well as a review of features of the data of the existing systems. Therefore, the novelty of this approach lies in developing an intelligent database for the enrichment of geographical maps with information about the accessibility of urban pedestrian areas for people with mobility problems.
Highlights
In the recent years, there has been an exponential increase in the number of smartphones, tablets, and PCs as well as their applications
The work presented in this paper proposes a conceptual data model for updated dynamic database (PostGIS) for Maps for Easy Paths, or
The Maps for Easy Paths (MEP) project is based on a user involvement and user-centered design approach that involves users actively in the whole design process, focusing on the “designing for users”, but on the “designing with users
Summary
There has been an exponential increase in the number of smartphones, tablets, and PCs as well as their applications. In today’s life, using Information Technology, smartphones or tablets or PCs, has become very common and paving way for users to have the ability to view and access information on the accessibility of paths in a cities. Parallel with this exponential increase in the use of smartphones, tablets and PCs is the availability of public data that provides for a potential use of Geo-located content, at low cost and infrastructure-less source of information for urban sensing in Smart Cities. Educational, Scientific, and Cultural Organization (UNESCO) more than one billion people have some form of disability in the world This corresponds to about 15% of the world’s population [1]. In this regard; travelling through cities is one of the main concerns for people with mobility challenges
