The Safety Risk Model (SRM) has been helping people in GB rail take sound, risk-based decisions for over two decades. It describes and quantifies the different risks associated with railway operations and maintenance. It helps decision makers set safety priorities and analyse safety-related costs and benefits so they can confidently and demonstrably meet legal requirements and wider business objectives.
What is the Safety Risk Model?
A good understanding of risk is required to deliver a safer, more efficient and sustainable rail system. The consideration of safety performance and risk helps make informed judgements and take safe decisions. Our Safety Risk Model (SRM) provides a network-wide view of risk and is used to support risk-based decision making.
Safety Risk Model: Improving safety and reducing costs
Learn how the SRM has made improved safety and saved the industry tens of millions of pounds in unnecessary expenditure. It supports safety planning, safety monitoring, analysing options and managing change, both nationally and locally. It is a particularly powerful tool when a decision involves complex trade-offs between costs and benefits.
The Safety Risk Model (SRM) was reviewed and rebuilt in 2021/22 through research findings that informed user needs and new modelling approaches. The work led to the development of SRM version 9 which provides access to more and better-quality data.
The Safety Risk Model (SRM) helps decision makers set safety priorities and analyse safety-related costs and benefits to meet legal requirements and wider business objectives. SRM version 9 provides access to quality data which can be incorporated into or derived from the model for specific applications.
