Speed Management Hub

  • Overview
  • FAQ
  • Resources

Speed is one of the main risk factors in road crashes, and is often cited as being the leading contributor to death and serious injury on the world’s roads. This is because:

  • Higher speed is associated with a significantly higher crash risk – even small increases in speed can have a big consequence

  • The probability of injury and the severity of a crash increases rapidly with higher impact speeds.

The collective impact of speed as a contributor to crash risk on society is huge, but it is often only when we consider the impact on an individual that we can comprehend the true effect on people’s lives. And this is clearly demonstrated in the example below:

Speeding hurts us all – and the impact is life-changing ⌵︎

Alex was 32 and with his wife Lisa parented two beautiful kids. They ran a small business together and employed several other people to work on their business. In his leisure time, Alex took out his boat for fishing with his friends, and his only self-proclaimed vice was playing video games, recreationally. A good life, right?

That evening, he was out walking the family dog, Chels, and crossing a local street intersection. The street was speed-posted at 40km/h. A driver though had chosen to go above the speed (roughly 50km/h) and hit Alex and Chels. Chels was killed at the scene, and Alex was seriously injured. He had a broken leg, broken ribs, dislocated joints, laceration and contusion and a collapsed lung.

Later, more detailed medical examinations to assess the Abbreviated Injury Scale (AIS) confirmed that he had 50% chance of dying at the scene of the crash. He spent 40 days in total in hospitals and outpatient facilities and went through a host of surgeries.

The science behind the Safe System approach (Davis, G.A., 2001) tells us that if the driver was going at the speed limit, i.e., 40km/h, Alex’s chance of getting seriously hurt were almost 25% less. And if the speed limit was set at the Safe System speed of 30km/h, he was only 30% likely to suffer serious outcomes – almost 63% less than when hit at 50km/h.

But this was not the end for Alex – speeding and the consequent human suffering is more vicious than that. Six months later, when interviewed as a part of a longitudinal study of road crash injury recovery, Alex was still in continuous pain, suffering anxiety and recurrent nightmares, limping and in no shape to work and enjoy his family life and hobbies.

At the 12-months mark, the situation had become disconcerting. Alex’s marriage had come to an end, and he was depressed and suffered intense anxiety attacks. He had lost the business and took up gambling and was socially withdrawn. Once an upbeat healthy man, he now had recurrent suicidal thoughts.

As the road safety community, we still hope to bring Alex’s life back on track – however, we believe it is comparatively easier to prevent such tragedies in the first place. This is where Speed Management comes in.

SPEED MANAGEMENT FRAMEWORK ⌵︎

Speed management involves a coordinated approach to addressing inappropriate speeds on a road or across a whole road network. The following figure shows the proven actions that need to be taken - sometimes concurrently - to ensure that speed management is successful and effective.

Under the new BIGRS Program 2020-2025, GRSF is the host of the Speed Management Hub. 

In this platform, the GRSF team provides evidence-based road safety knowledge to help manage speed through infrastructure interventions, effective enforcement, targeted awareness measures, and vehicle technology. Key engagements from this focus area include:

  • Provision of technical expertise to program partners, countries and cities on speed management;

  • Preparation and publication of Global Speed Management Guidelines;

  • Research analysis on the economics and benefits of speed management;

  • Technical analysis for road engineering solutions promoting speed management.

The Speed Management Hub also allows the wide dissemination of frequently asked questions (FAQs) on speed management, together with a rich library, latest news and best practices on this topic. 

FAQs ON SPEED MANAGEMENT ⌵︎

As the BIGRS' Speed Management Hub, GRSF is tasked with assisting all initiative partners in speed management related issues and ensuring dissemination of best practices in the field. The GRSF team has already received a series of questions from several partners and was able to address these in a timely manner. With the current travel restrictions due to COVID-19 and to ensure good practices in the field are still disseminated, GRSF has created this online platform that allows the wide dissemination of frequently asked questions (FAQ) on speed management, together with a comprehensive resource library and latest news and examples of best practices on this topic. 

The core topics the GRSF team is planning to address on this platform are:

  • Introduction to speed management

  • Policies and strategies for speed management

  • Speed management through road engineering

  • Speed management through traditional enforcement

  • Speed management through automated enforcement

  • Speed management through vehicle technology

  • Speed management through road user communication, education and engagement

  • Speed management fallacies / myth busting
