Road safety leaders from around the world are preparing for a significant shift in how infrastructure risk is measured, prioritised and communicated with the upcoming launch of iRAP Star Rating Model Version 3.10 in May 2026.
Following five highly attended #RAPKnowledgeLive global webinars in March and April, iRAP has now made recordings available in English, French, Portuguese and Spanish, ensuring partners and practitioners across regions can engage with the changes in their preferred language.
Watch the Recordings: Now Available in Four Languages
To support a smooth and inclusive global transition, iRAP has released recordings of the Star Rating Model 3.10 sessions across multiple regions and languages.
English Sessions (Now Available)
-
Watch Session 1 Recording (North America, Europe, Africa, Middle East)
-
Watch Session 2 Recording (Asia, Australia-Pacific)
These sessions provide a detailed technical walkthrough of the model changes and transition guidance for current projects in ViDA.
New: French, Spanish and Portuguese Recordings
Practitioners can now access dedicated language sessions, delivered by iRAP experts for regional audiences:
- French – West & Central Africa and Europe
- Spanish – Latin America and Spain
- Portuguese – Brazil, Portugal and Lusophone partners
These sessions cover the same core content as the English webinars, with regionally relevant examples and live audience Q&A, helping ensure consistent understanding and application worldwide.

👉 Access all supporting documents and materials:
- Download the iRAP Star Rating Model Update Explainer Note: Details the changes made to the crash risk models, risk factors and coding guidance.
- Download the iRAP Methodology Reference Guide: This consolidated reference guide fully describes the iRAP models and risk factors, as well as the evidence which underpins these.
- Frequently Asked Questions (FAQ) document answers common technical and data management queries.
Get Ready for May 2026
With enhanced transparency, stronger VRU protection and improved sensitivity to safety gains, Star Rating Model Version 3.10 represents a major advance for evidence‑based road safety investment.
Road authorities, engineers, researchers and partners are encouraged to:
- Watch the relevant session recording in their preferred language
- Review the updated guidance materials
- Prepare internal teams for the transition in ViDA
Together, these changes will support the shared goal of creating a world free of high-risk roads for all road users.
What This Means for Existing and Future Projects
To ensure consistency, projects already underway using Version 3.02 in ViDA will remain unchanged. However, Version 3.10 will become the default model for all new assessments from May 2026.
Transition guidance, technical documentation and updated specifications—including the Star Rating Model Update Explainer Note and the iRAP Methodology Reference Guide—are available to support partners through the change.
ViDA users will be notified by email about the launch of version 3.10 in ViDA.

A Major Step Forward for Global Road Safety
Developed after a comprehensive five‑year evidence review led by the iRAP Global Technical Committee, Version 3.10 represents the most substantial update to the Star Rating methodology since version 3.02. The new model incorporates the latest global crash‑risk research and aligns more closely with Safe System principles and the UN Decade of Action for Road Safety.
Key drivers for the change include:
- Latest Global Evidence: Incorporates the latest research and global evidence on crash risk.
- Safe System Alignment: Aligns risk factors and injury relationships with Safe System principles.
- Vulnerable Road User (VRU) Focus: Enhances the accuracy of risk assessments, particularly for pedestrians and bicyclists, and to a lesser extent, motorcyclists.
- Robust Outcomes: Ensures assessments remain robust, repeatable and aligned with real-world injury outcomes.
What’s New in Star Rating Model Version 3.10?
The new model introduces several important enhancements that road authorities and practitioners should be aware of ahead of the May 2026 transition. [irap.org], [irap.org]
Key Methodology Enhancements
- Major VRU Updates: Significant changes to pedestrian and bicyclist models, including a new “Bicyclist Crossing” crash type.
- Granular Risk Factors: Implementation of 1 km/h speed increments and 1,000 vehicle-per-lane increments for external traffic flow.
- Unified Banding: A consistent Star Rating banding system across pedestrian and bicyclist models to ensure uniform interpretation.
- Zero Star Rating: A new ‘Zero Star’ band to help differentiate sections of road with extremely high risk and prioritise them for treatment.
- Decimal Star Ratings: A more sensitive and nuanced understanding of road safety that goes beyond traditional whole-Star thresholds.
- Operating Speed Functionality: New ViDA features allow users to produce Star Ratings based on operating speeds alone.
