Resources

iRAP produces a wide range of resources to support road safety practitioners and advocates.

These include practical guides to the iRAP methodology, interactive road assessment tools such as Star Rating Demonstrator and our core advocacy publication Vaccines for Roads.

We also host one of the largest online databases of thought leadership publications on road safety techniques and in-depth inspection reports on national roads.

ViDA

All the iRAP road survey data which is gathered around the world, is processed through ViDA, our central data base.

It’s easy-to-use and contains the results from almost 1,000,000km of road assessments. You can use it to create life-saving Star Ratings and Safer Road Investment Plans.  One of the great things about ViDA is that it uses a ‘risk worm’ to segment roads into different levels of risk. This means you can target investment to deliver the biggest return in lives saved and serious injuries prevented.

We’re constantly updating ViDA to make it even more flexible and easy to use.

The ‘iRAP Methodology’ fact sheets describe the Star Rating and Safer Roads Investment Plan methodologies, while the ‘iRAP Road Attribute Risk Factors’ fact sheets describe the risk factors used in the models.

We translated the iRAP Methodology fact sheets into the following languages to assist:

  • French
  • Spanish
  • Portuguese

The Road Attributes Risk Factor fact sheets have been translated into French to assist also.

Model Updates

iRAP is a charity and encourages partners and supplier networks to develop their own skills to lead, undertake and implement iRAP assessments.

Ensure you make contact with the programme lead in your country to ensure your project involves the necessary local stakeholders and is integrated with existing and planned work in the country.  Refer to "Where we work" for details.

In order to support our partners around the world we produce a compact range of documents that outline our technical  requirements and the context of our work.  They are regularly revised to include best practice and new learning.

Specifications

iRAP produces a number of  specifications that can be used in the procurement and management of iRAP-specification activities.

The specifications include:

  • A standard ‘Terms of Reference’ that can be used as the basis of a project plan and/or in the process of engaging consultants to deliver services
  • Minimum specifications for an iRAP Inspection (survey and coding).
  • Minimum specifications for the collection of supporting data.

Road Safety Toolkit

The Road Safety Toolkit provides free information on the causes and prevention of road crashes that cause death and injury.  Building on decades of road safety research, the Toolkit helps engineers, planners and policy makers access relevant information on countermeasure design, effectiveness, cost and implementation issues.

The Road Safety Toolkit is the result of collaboration between  iRAP, the Global Transport Knowledge Partnership (gTKP), ARRB Group, Austroads, the Global Road Safety Facility, Road Safety Fund and FIA Foundation.
