Best Practices for Conducting a Road Safety Audit in the U.S. Highway System

Introduction

As the U.S. highway network expands and vehicle volumes increase, ensuring road user safety is more critical than ever. A road safety audit USA is a formal safety performance examination of existing or future road infrastructure conducted by an independent, qualified team. This proactive and data-driven practice is now central to the transportation strategy of state DOTs and municipalities across the country.

With growing interest in AI road safety inspection, NSV road data collection, and app based road surveys, the traditional safety audit is undergoing a digital transformation. This blog outlines best practices for conducting effective road safety audits in the USA, focusing on the integration of AI road safety audit systems and automated road data capture.

What is a Road Safety Audit in the USA?

A road safety audit (RSA) in the United States is a structured assessment conducted during the planning, design, construction, or operational stage of a roadway. The goal is to identify safety concerns for all road users including drivers, pedestrians, cyclists, and the mobility-impaired.

Audits can be applied to:

• New road construction projects
• Reconstruction and rehabilitation projects
• Existing roads with high crash frequencies or risky layouts

Unlike reactive crash data reviews, RSAs are proactive and field-based, aiming to prevent crashes before they occur.

The Eight-Step RSA Process

To ensure consistency and reliability, RSAs typically follow an eight-step process:

1. Define the Project and Audit Objectives

Identify the location or project stage and clarify the scope, timeline, and team roles.

2. Assemble the Audit Team

An independent, multidisciplinary team should include traffic engineers, safety experts, planners, and sometimes law enforcement personnel.

3. Conduct a Pre-Audit Briefing

Review project documents, past crash data, and background information to set expectations.

4. Perform Field Review

Visit the site during day and night, peak and off-peak hours. Note driver behavior, signage clarity, lighting, surface condition, and potential hazards.

5. Analyze Data and Document Findings

Prepare a detailed report including identified issues, photos, risk severity, and actionable recommendations.

6. Present Audit Findings

Share insights with the project owner, design team, or municipality.

7. Receive Formal Response

The agency responds with agreed-upon actions or justifications for non-implementation.

8. Follow-Up Monitoring

Track implementation of recommendations and evaluate their outcomes.

2. Use App Based Road Surveys

App-based tools allow audit teams to collect GPS-tagged imagery, notes, and risk scores directly from the field using smartphones. These digital workflows are quicker, consistent, and more scalable for county-wide audits.

3. Adopt NSV Road Data Collection

NSV (Network Survey Vehicle) technology provides high-speed road imaging and pavement profiling. Data captured by these vehicles is crucial for automated road data capture, enabling real-time risk identification and prioritization.

4. Integrate with Traffic and Pavement Data

An effective audit must integrate traffic survey data with roadway conditions, crash history, and environmental context to gain holistic insights.
