Roadvisionai enables data-driven infrastructure intelligence that strengthens compliance with national standards like IRC 35 2015, ensuring safer and more consistent road markings across India. With the rise of AI pavement condition monitoring, authorities can now digitally verify marking quality and durability at scale.
India’s rapidly expanding road network demands consistency, durability, and high safety standards in pavement design. Road markings may appear simple, but they are among the most critical elements of traffic control, guiding millions of motorists, cyclists, and pedestrians daily.
The framework governing these markings is IRC 35 2015, issued by the Indian Roads Congress. This code standardises marking types, materials, colours, dimensions, and maintenance practices nationwide.
As the saying goes, “A clear path prevents a dangerous journey.” In traffic engineering, clarity saves lives.
IRC Code 35 is a national standard that ensures uniform pavement marking practices across:
First introduced in 1970 and comprehensively revised as IRC 35 2015, the code reflects:
Its core objective is simple: road markings in India must be consistent, durable, and clearly visible nationwide.
Road markings provide continuous visual guidance, especially during:
Under IRC 35 2015, markings are designed to:
Well-maintained markings enhance driver confidence and road discipline. Modern AI road inspection tools now support continuous compliance monitoring.
IRC Code 35 classifies road markings into seven primary categories:
Run parallel to traffic flow and regulate lane behaviour.
Examples:
Placed across the direction of traffic, typically at intersections.
Examples:
Used in high-conflict or restricted zones.
Examples:
Highlight special-use or safety-sensitive zones:
Guide directional movement before intersections or roundabouts.
Examples:
Text-based pavement messages such as:
Define dedicated infrastructure spaces:
These markings support organised and inclusive road usage.
IRC Code 35 specifies materials based on durability requirements and traffic intensity.
Material selection must align with Ministry of Road Transport and Highways specifications for national compliance.
Night-time visibility depends on embedded retroreflective glass beads that reflect headlights back to drivers.
irc 35 2015 mandates minimum retro-reflectivity levels to ensure safety during:
Without proper reflectivity, markings lose their functional value. Today, automated pavement distress detection helps agencies track degradation patterns efficiently.
Uniform colour coding ensures consistent interpretation nationwide:
Colour selection may vary slightly based on pavement contrast requirements.
IRC Code 35 mandates periodic inspection of:
Routine audits and scheduled repainting are critical. Faded or misaligned markings increase confusion and crash risk. Digital pavement survey system solutions now support structured evaluation cycles.
Road marking compliance directly contributes to AI road safety audit frameworks by improving lane discipline and reducing conflict zones.
Advanced road crack detection AI further ensures pavement and marking integrity are evaluated together for holistic highway safety.
IRC Code 35 forms the backbone of structured pavement marking practices in India. By standardising marking categories, materials, colour codes, and maintenance protocols, IRC 35 2015 strengthens traffic discipline and reduces accident risks nationwide.
For engineers, planners, and contractors, implementation is not merely regulatory compliance. It is a commitment to safer infrastructure, stronger visibility standards, and sustainable roadway performance.
Because road safety is not a luxury. It is a necessity.
Q1. What is IRC Code 35?
IRC Code 35 is the official Indian Roads Congress guideline that standardises pavement marking design, materials, and maintenance practices across India.
Q2. Which materials are recommended under IRC Code 35?
Thermoplastic markings, waterborne paints, cold-applied plastics, adhesive tapes, and retro-reflective glass beads are recommended depending on traffic intensity and durability requirements.
Q3. How does IRC Code 35 improve road safety?
By enforcing visibility standards, structured placement rules, and maintenance requirements, the code enhances lane discipline, pedestrian protection, and overall highway safety.
