Towards a real-time distributed feedback system for the transportation assistance of PwD

TL;DR

This paper addresses the challenge of safe, accessible urban mobility for people with disabilities by obstructed transit points in cities. It proposes an integrated distributed sensor network with three subsystems—Mark Inaccessible City Point System (MICPS), Live Data Analysis and Response System (LDARS), and Obstacle Detection and Prevention System (ODPS)—to provide real-time feedback and route adaptation for PwD. The approach combines sensor networks, cyber-physical system integration, and real-time feedback to inform users and authorities and to recalibrate routes when ramps are blocked. The modular architecture supports extension to additional assistive services and scalable deployment, offering a practical foundation for safer, more inclusive city transport.

Abstract

In this work we propose the design principles of an integrated distributed system for the augment of the transportation for people with disabilities inside the road network of a city area utilizing the IT technologies. We propose the basis of our system upon the utilization of a distributed sensor network that will be incorporated by a real-time integrated feedback system. The main components of the proposed architecture include the Inaccessible City Point System, the Live Data Analysis and Response System, and the Obstruction Detection and Prevention System. The incorporation of these subsystems will provide real-time feedback assisting the transportation of individuals with mobility problems informing them on real-time about blocked ramps across the path defined to their destination, being also responsible for the information of the authorities about incidents regarding the collision of accessibility in place where the sensors detect an inaccessible point. The proposed design allows the addition of further extensions regarding the assistance of individuals with mobility problems providing a basis for its further implementation and improvement. In this work we provide the fundamental parts regarding the interconnection of the proposed architecture's components as also its potential deployment regarding the proposed architecture and its application in the area of a city.
