IRC SP 21 Guidelines Explained: Smart Road Inventory Management with AI

With India’s expanding road infrastructure, the demand for precise and structured road inventory management has never been greater. The Indian Roads Congress (IRC) introduced IRC SP 21 to standardize and streamline road inventory surveys. But traditional manual survey methods are often time-consuming, error-prone, and costly. That's where modern technologies like AI-based road asset management tools come into play.

This blog explains the key provisions of IRC SP 21, its role in India’s road sector, and how AI-driven platforms like RoadVision AI are revolutionizing compliance and performance in road inventory inspection.

What is IRC SP 21?

IRC SP 21: "Manual for Planning and Design of Road Inventory" is a technical document by the Indian Roads Congress (IRC) that outlines a structured approach for recording physical features of roads. It is a critical reference for government engineers, road contractors, consultants, and stakeholders in road asset management India.

The goal is to create a standardized road asset database for planning maintenance, improving safety, and optimizing infrastructure investment.

Why IRC SP 21 Compliance Matters?

Compliance with IRC SP 21 guidelines ensures:

• A uniform format for road feature documentation
• Efficient planning and budgeting of maintenance
• Improved road safety and inventory accuracy
• Better coordination between departments like MoRTH, NHAI, PWDs, and ULBs

‍

Traditional Road Inventory Challenges

Traditional road inventory methods involve:

• Manual inspections
• Physical measurements
• Paper-based reporting

These techniques are labour-intensive, prone to human error, and suffer from data inconsistency, especially across large-scale networks.

‍

AI-Based Road Inventory Management: A Game Changer

Modern AI platforms like RoadVision AI's Road Inventory Inspection solution automate the survey process using:

• High-resolution cameras
• Drones
• LiDAR and GPS sensors
• AI-based object detection and classification

These tools extract features such as:

• Road width, type, and surface
• Median and shoulder conditions
• Signages and markings
• Roadside assets like guardrails, trees, poles, culverts, and bus stops

The result is a high-accuracy, geo-referenced digital inventory compliant with IRC SP 21.
