Speed Management Manual

15 December 2023

The Second Edition of the World Health Organisation (WHO) Speed Management Manual  has been released, sharing the link between reduced speeds and safer roads through iRAP partner case studies.

The management of speed remains one of the biggest challenges facing road safety practitioners around the world. The speed at which a vehicle travels directly influences the risk of a crash as well as the severity of injuries sustained, and the likelihood of death resulting from a crash.

Research shows that a 5% cut in average speed can result in a 20% reduction in the number of fatal road traffic crashes. We also know that when speed goes down, the iRAP Star Rating goes up! Speed management must be a part of every road design and every review of existing roads.
