Road Safety Audit

A Road Safety Audit (RSA) is a systematic and independent review of a road scheme, at the design, construction, or operational stage, to identify potential road safety hazards and recommend corrective measures before they lead to accidents. In India, RSA is mandated by the Ministry of Road Transport and Highways (MoRTH) for all national highways and is increasingly required by state governments as part of major road project approvals.

What is a Road Safety Audit in government procurement?

MoRTH's guidelines on Road Safety Audit (based on IRC SP:88 and IRC SP:99) require RSAs at four defined stages of a highway project: Stage 1 at the feasibility study stage when alignment alternatives are being considered; Stage 2 at the detailed design stage before construction drawings are finalised; Stage 3 during construction to check that safety features are being built as designed; and Stage 4 post-opening, typically 6-12 months after the road is opened to traffic to assess real-world performance against design intent.

An RSA is conducted by a team of trained auditors, independent of the designers and the procuring agency, following a structured checklist. The audit team physically inspects the road or its designs, identifies hazardous features (inadequate sight distances, poorly placed median openings, absence of delineation on curves, inadequate pedestrian crossings, poorly lit intersections), and prepares an RSA report with findings and recommendations.

The procuring agency (NHAI, state PWD) must formally respond to each finding, accepting the recommendation and committing to implementation, or providing a reasoned response for not accepting it. This "acceptance or rejection with reasons" is documented and retained as the formal record of the audit.

RSA consultancy contracts are tendered by NHAI and state highway agencies, typically through QCBS-based selection of qualified consultancy firms. Eligibility for RSA contracts requires auditors with IRC-recognised RSA training (certified by CRRI or other MoRTH-approved institutions) and experience of similar audits.

Black spot identification and improvement, targeting specific locations with high accident frequency on existing roads, is a related procurement segment. Black spot improvement projects involve geometric design changes, signage, delineation, and sometimes grade separation, and are tendered as civil works contracts funded by the Motor Vehicle Accident Fund and state road safety funds.

Why it matters for bidders

For design consultancies and safety engineering firms, RSA contracts are recurring opportunities tied to the large highway development programme. Every new NHAI project under EPC or HAM requires RSA at multiple stages, and the RSA market is proportional to the highway construction volume.

For highway construction contractors, RSAs matter because Stage 3 (construction) RSA findings may require design changes or additional safety features that the contractor must accommodate. If the RSA identifies a safety issue attributable to a design error that the EPC contractor made, the cost of rectification falls on the contractor. Companies should review RSA requirements in their EPC contracts carefully.

State highway departments that have not historically mandated RSA are increasingly doing so, partly in response to court directions from state High Courts on road safety, and partly under World Bank and ADB loan conditions that require RSA as part of project implementation safeguards. This is creating RSA demand beyond NHAI projects.

Example

NHAI engages a road safety auditing firm for a Stage 2 RSA on a 120-km EPC project in Andhra Pradesh. The RSA team reviews all design drawings and visits the alignment. They identify 18 findings, including median opening spacing that does not meet IRC 43 recommendations, three curves where sight distance is below the stopping sight distance required for the design speed, and a pedestrian crossing location near a school that is not visible to approaching traffic. The audit report is submitted to NHAI's Project Director. NHAI accepts 15 findings and instructs the EPC contractor to revise designs. Three findings are rejected with documented technical reasoning. The corrected designs are re-checked at Stage 3 when construction begins.

Key rules / thresholds

IRC SP:88 (Guidelines for Road Safety Audit) is the primary guidance document for RSA methodology in India. RSA auditors must be trained and certified, CRRI runs the approved training programme. NHAI's concession agreement for EPC projects includes the RSA requirement as a contractual obligation, with the contractor required to facilitate Stage 3 audits and implement accepted recommendations within 30 days of the Stage 3 RSA report.
