Pedestrian Safety Information Service for Persons with Disabilities

Overview

Domestic map services focus primarily on route guidance for general pedestrians, presenting limitations that make them difficult for transportation-disadvantaged individuals such as the visually impaired and physically disabled to use. Furthermore, insufficient pedestrian pathways and safety facilities for the disabled persistently cause problems, such as difficulty entering buildings due to narrow thresholds.

Particularly, pedestrian route information for persons with disabilities often fails to reflect the accessibility status of individual facilities, frequently leading to inconvenience when encountering unexpected obstacles during travel. Therefore, this project developed a pedestrian safety information provision system for persons with disabilities, based on AI analysis, to support optimal route guidance.

Project description

This system provides optimized walking navigation tailored to specific disability types, supporting safe mobility for individuals with visual and physical disabilities.

• AI-Based Optimal Walking Route Guidance
  • It guides users along AI-based optimal walking routes tailored to the specific walking characteristics of each disability type, such as visual or physical impairments. It also provides real-time movement routes that comprehensively consider road conditions, sidewalk width, and the presence of obstacles.
• Providing Public Transportation Accessibility Information
  • By analyzing and providing real-time availability of bus stops, subway stations, and other facilities, it enhances mobility for people with disabilities. It also improves public transportation convenience by providing detailed information such as the presence of elevators and ramps.
• Providing Accessibility Information for Public and Convenience Facilities
  • AI analyzes the accessibility of hospitals, public institutions, cultural facilities, and more to enhance the convenience of daily life for people with disabilities. It also provides practical mobility support by offering information on facility operating hours, access routes, and dedicated entrances for people with disabilities.

Key technological features

• AI-based Route Optimization Algorithm: Provides personalized walking routes by learning walking patterns for each disability type; AI analyzes real-time traffic and terrain data to recommend optimal travel paths
• Geographic Information System (GIS) Integration: Links accessibility data for public and private facilities with GIS to evaluate accessibility, analyzes facility-specific access feasibility, and provides real-time updates for the latest information
• Real-time Data Updates and Navigation: Enhances mobility for people with disabilities by providing transportation information such as bus stops and subway stations. Guides optimal routes reflecting real-time variables like road construction and elevator malfunctions

Expected outcomes

It is expected that the user base for this specialized navigation system, designed not only for persons with disabilities but also for those with walking difficulties, will expand to include general pedestrians. Furthermore, it can be extended to various fields such as smart city welfare platforms and barrier-free tourism services.

Before (as-is)
Insufficient guidance facilities for pedestrian paths and disabled safety facilities; absence of navigation services for safe pedestrian routes for the disabled

After (to-be)
Accessibility information for customized routes, facilities, and public transportation can be provided through a unified pedestrian system offering a seamless experience

Launch year: 2024
