Unlocking Road Transport Efficiency with IRC Code SP 28: Road Transport and Energy (1995)

‍

The efficient management of road transport and energy resources is essential for sustainable development in any country. The Indian Roads Congress (IRC) Code SP 28, "Road Transport and Energy" (First Revision, 1995), is a comprehensive guide addressing the vital connection between transportation infrastructure and energy conservation. This blog explores the significant aspects of this IRC Code and its role in promoting efficient road infrastructure in India.

The Importance of IRC Code SP 28

‍
Originally published in 1984 and revised in 1995, IRC SP 28 reflects the Indian Roads Congress's efforts to provide updated guidance on energy-efficient road transport. The document acknowledges the growing energy demands of the transport sector and suggests measures to optimize energy use, thereby reducing the environmental and economic burdens associated with excessive fuel consumption.

Key Highlights of IRC Code SP 28

‍

1. Energy Consumption Trends in Transport

The transport sector is a significant consumer of commercial energy, with road transport accounting for the bulk of liquid fuel usage. The IRC Code highlights India's heavy reliance on diesel, which forms 87% of fuel consumption in road transport, as compared to 13% for petrol. This reliance necessitates urgent steps for energy conservation to ensure sustainable growth.

2. Energy Conservation through Improved Road Infrastructure

One of the core recommendations of the code is improving road conditions to minimize energy loss. Poor road surfaces increase vehicle fuel consumption due to higher friction. Key measures include:

• Upgrading earthen roads with bituminous surfacing.
• Ensuring timely maintenance to reduce road roughness, which directly impacts fuel consumption.
• Building cement concrete roads for long-term benefits, including up to 9% fuel savings for heavy vehicles.

3. Impact of Vehicle Load and Speed

The IRC Code emphasizes that vehicle load and speed significantly affect fuel consumption. It suggests:

• Promoting multi-axle trucks and trailer combinations to optimize fuel efficiency and reduce road damage.
• Encouraging adherence to optimum speed ranges (30-50 km/h) for different vehicle categories to achieve fuel savings.

4. Benefits of Wider Pavements and Signal Optimization

Narrow roads and traffic congestion contribute to frequent stops, accelerations, and decelerations, leading to excessive fuel consumption. Recommendations include:

• Widening roads to accommodate traffic and reduce congestion.
• Installing synchronized traffic signals to improve flow and minimize idling fuel wastage.

5. Alternative Fuels and Technologies

While petroleum-based fuels remain dominant, the IRC Code identifies the potential of alternative fuels such as compressed natural gas (CNG), methanol, and hydrogen. It also advocates for technological advancements in vehicle design, such as lightweight materials and aerodynamic shapes, to improve fuel efficiency.

Strategies for Energy Conservation in Road Transport

‍

The IRC SP 28 provides a blueprint for energy conservation, which includes:

• Traffic Management: Promoting public transport, developing mass rapid transit systems (MRTS), and managing traffic flow through intelligent systems.
• Road Infrastructure Planning: Prioritizing expressway construction, bypasses, and the removal of roadside encroachments.
• Policy and Awareness: Educating drivers on fuel-saving techniques and implementing stricter penalties for excessive emissions.

‍

Conclusion

‍
IRC Code SP 28 serves as a vital resource for policymakers, engineers, and urban planners to address the challenges of energy conservation in road transport. By adopting its recommendations, India can make significant strides in reducing fuel consumption, lowering carbon emissions, and enhancing the sustainability of its transport sector.
