Taking Safe Decisions - Cost-Benefit Analysis
20/05/2019
Cost-benefit analysis (CBA) weighs the expected costs of one or more options against the expected benefits to support a decision as to which option(s) should be implemented. It can be used by railway companies to assist in taking safety-related decisions.
Guidance on the use of cost-benefit analysis when determining whether a measure is necessary to reduce risk so far as is reasonably practicable describes how CBA can be used to inform a decision. Further information on the wider decision-taking process can be found in Taking Safe Decisions, which sets out the industry consensus view of how safety is taken into account when taking decisions.
