About the Toolkit
The Road Safety Toolkit provides free information on the causes and prevention of serious road crashes. Building on decades of road safety research, the Toolkit helps engineers, planners and policy makers develop safety plans for car occupants, motorcyclists, pedestrians, bicyclists, heavy vehicle occupants and public transport users.
The Road Safety Toolkit is the result of collaboration between the International Road Assessment Programme (iRAP), the Global Transport Knowledge Partnership (gTKP) and the World Bank Global Road Safety Facility.
ARRB Group, Kate McMahon and John Fletcher (TRL) provided expert advice during the Toolkit’s development.
Austroads provided permission to use concepts and information from Austroads road safety engineering toolkit (www.engtoolkit.com.au) in this website. The Austroads toolkit fulfils a similar purpose to this website, although is aimed at Australian and New Zealand practitioners specifically.
Our 3-minute video provides a brief overview of how to use the Toolkit.
