Once high risk locations have been identified, appropriate interventions must be assessed and selected to address this risk.
Effective road infrastructure interventions are available to help address road safety problems, regardless of the cause. These can reduce the likelihood and/or severity of a crash. Some interventions can almost eliminate death and serious injury, while others provide more limited (or incremental) improvements.
Interventions should be designed to address risk at a specific location, routes or across the whole road network.
Detailed information is available on effective interventions and when these should be used, including for those in LMICs.
Interventions can be selected based on the expected reduction in injury, but other factors should also be considered when selecting interventions.
Once appropriate locations have been identified, there is a need to assess which combination of interventions and/or locations will produce the greatest reduction in fatal and serious injuries for the budget available.
Economic assessment should be undertaken to identify the most cost-effective use of resources. The process for this is well established, including for LMICs, and tools are available to assist in this task.
