ISO 28564-4:2023

Overview

ISO 28564-4:2023 - Public information guidance systems - Part 4: Installation and assessment - sets out principles, requirements and methods for the installation and assessment of public information guidance (wayfinding) systems. It applies to public places such as bus and railway stations, airports, shopping centres, hospitals, museums, parks and commercial buildings. The document helps organizations design, install and evaluate signage, location maps and information indexes while promoting inclusive, safe and coordinated wayfinding.

Key Topics

• Preparation before installation
  • Target audience analysis (demographics, visitor flow, mobility modes, familiarity)
  • Spatial characteristics and influence of building layout
  • Renovation considerations and existing maintenance records
  • Collaborative planning with architecture, lighting, traffic, landscaping and monitoring
• Installation principles
  • Conformity with ISO 28564 Parts 1–3 and related standards
  • Systematic approach to combine guidance elements into a coherent system
  • Continuity and placement of signage at decision points (entrances, junctions)
  • Consistency in symbols, terminology, colours and mounting practices
  • Conspicuity, safety, inclusivity and environmental sensitivity
• Positioning and mounting
  • Location signs and direction signs: setting, conveying information and displacement
  • Mounting height considerations and avoidance of blocking safety signs or systems
  • Information index signs, location plans, diagrams and maps
• Materials, inspection and maintenance
  • Guidance on material selection appropriate to environment and durability
  • Scheduled inspection and maintenance to ensure legibility and effectiveness
• Assessment
  • Methods to evaluate wayfinding outcomes objectively and optimize systems based on results
  • Annex provides an assessment checklist for public information guidance systems

Applications

Who uses ISO 28564-4:

• Wayfinding designers and sign contractors for airports, stations and shopping centres
• Facility managers, urban planners and transport authorities implementing signage schemes
• Architects and lighting/landscaping teams coordinating installations with built environments
• Accessibility and compliance teams assessing signage for diverse user needs

Practical uses:

• Developing installation briefs and mounting plans
• Conducting target-audience and spatial analyses before deployment
• Carrying out post-installation assessments and maintenance programs
• Coordinating signage with safety signs, lighting and advertising
