Understanding IRC Code: IRC:SP:117-2018 Manual on Universal Accessibility

‍

The Indian Roads Congress (IRC) plays a pivotal role in establishing design and construction standards for road infrastructure in India. One of its significant publications, the IRC:SP:117-2018, titled "Manual on Universal Accessibility for Urban Roads and Streets," offers comprehensive guidelines to create accessible, inclusive, and obstacle-free urban road systems. These standards aim to ensure that public spaces can be utilized by all individuals, including persons with disabilities, senior citizens, and families with young children.

‍

This blog explores the essential elements of IRC:SP:117-2018, providing insights into best practices, design considerations, and the importance of universal accessibility.

Importance of Universal Accessibility

‍

Universal accessibility refers to the design of urban environments and transport systems to be usable by all individuals without needing adaptations or specialized solutions. The IRC emphasizes that accessible urban roads and streets promote safety, social inclusion, and sustainability.

‍

Key Benefits:

‍

• Inclusivity: Supports the mobility needs of all individuals.
• Safety: Reduces potential hazards for vulnerable road users.
• Environmental Impact: Encourages walking and the use of non-motorized vehicles (NMVs).
• Social Integration: Enhances access to education, healthcare, and employment opportunities.

Key Guidelines in IRC:SP:117-2018

‍

Design Elements for Accessible StreetsThe manual emphasizes essential design principles, including:

1. Footpaths:
   • Minimum width of 1.8 meters to accommodate wheelchairs and strollers.
   • Non-slip surfaces with tactile pavers for visually impaired users.
2. Kerb Ramps:
   • Gradient not exceeding 1:10.
   • Proper tactile warnings to alert visually impaired users.
3. Crossings and Signals:
   • Well-marked pedestrian crossings.
   • Audible signals for persons with visual impairments.
4. Seamless Connectivity:
   • Continuous pathways connecting public transport terminals and key destinations.

‍

Public Transport Accessibility

‍

The manual stresses the need for accessible public transport infrastructure, including:

• Low-floor buses and precision docking.
• Accessible transit terminals with ramps, lifts, and tactile indicators.

‍

Safety and Maintenance

‍

Ensuring regular maintenance of accessible elements is crucial. The code highlights the importance of post-implementation audits and monitoring to maintain the accessibility features.Best Practices HighlightedThe manual provides examples of best practices from both Indian and international cities, such as:

• Delhi: Comprehensive footpath designs and accessible bus stops.
• Geneva: Pedestrian-friendly crossings with tactile guidance.
• Amsterdam: Integrated NMV lanes and cycle stands.

‍

Implementation Challenges

‍

The IRC:SP:117-2018 acknowledges several challenges, including:

• Knowledge Gaps: Lack of technical know-how among civic agencies.
• Inconsistent Implementation: Piecemeal adoption of accessibility features.
• Maintenance Issues: Inadequate attention to long-term upkeep.

‍

Conclusion

‍

The IRC:SP:117-2018 "Manual on Universal Accessibility for Urban Roads and Streets" provides invaluable guidance for creating inclusive and accessible urban environments. By adhering to these guidelines, urban planners, engineers, and policymakers can ensure a safer, more inclusive, and sustainable urban transport network.
