Road collisions cause immense human suffering and economic loss. The robust assessment of relevant costs is important in supporting Cost Benefit Analysis (CBA) of safety measures. In the UK, the methodology for evaluating these costs has been in use since 1990s. TRL has recently re-visited its pioneering work (O’Reilly, 1993; Hopkin & Simpson, 1995) assessing the costs of road casualties and highlighted the need to update the approach to determining cost-effective countermeasures if we are going to prevent the wasteful impact of road collisions on society and economies.
The resulting recommendations of this review point to the need of:
- Enhancing the current cost-benefit analysis framework concerning road safety
- Adopting a robust evidence base for appraising all casualty prevention interventions, including education, enforcement, and road and vehicle engineering safety measures
- Harmonising methodologies across countries
