Modelling the Relationship(s) Between Safety and Operational Performance

Abstract

Models have the ability to represent a specific viewpoint of situations or circumstances in the real world. This paper facilitates the understanding of the relationship between railway safety and operational performance by providing an overview of performance models and presenting a model framework that incorporates both elements of safety and operational performance in the rail industry. This framework, if further developed into a working model with complex equations will facilitate decision making by governments and stakeholders in the daily operations and investments of railways.
