Abstract

In order to include people of reduced mobility in the traffic system it is necessary to provide accessibility and information of the users to all the facilities surrounding them. By analysing the currently available information and communication technologies a new conceptual model of providing navigation services to the visually impaired persons has been proposed. This model is based on Cloud Computing platform, and this research describes the method of navigating the users based on accurate and updated data. The users’ requirements have been analysed according to the needs of the movement of visually impaired persons along the traffic network. The information and communication solutions with the function of informing these groups of users have to provide accurate and updated data, which is made possible by the proposed model. This research was conducted on the most frequent routes in the city of Zagreb. With the review of model efficiency user’s sense of security is increased in the amount of 87%.

The mentioned information can be substituted by the application of information and communication (IC) technologies and services, which defines the concept of assistive technologies in traffic [2]

Summary

Introduction

Persons with reduced mobility can be divided into several categories which depend on the level of their impairment. According to the latest available data there are 1,985 visually impaired persons in the City of Zagreb [1]. Out of this figure, 171 users are permanently employed, and this figure is defined as a relevant sample in carrying out this study (the mentioned persons move daily along the traffic network). One of the applications of assistive technologies is reflected in the use of IC solutions for the guidance and navigation of the users along the traffic network. The mentioned drawbacks can be substituted by the application of other technologies in the function of locating and navigating the users, as well as informing purposes [5]. POI markings have the role of informing the users about a certain facility, which is in their vicinity
