ABSTRACT
This chapter describes how an integrated risk assessment approach was taken which employed the health and safety executive Revised Fatigue Index to assess the proposed changes to shift patterns and the Structured What-IF Technique hazard identification technique to determine additional risk factors that could impair driver performance. The fatigue issue is of particular concern in the rail industry, where long journeys are common, and require constant vigilance by a single driver. The chapter reviews the driver monitoring systems aimed to identify whether the safeguards would be adequate to control the risks associated with the proposed operations or whether additional measures would be required and discusses the approach adopted, the main tool used, and how the results were made robust by their interpretation and use of supporting material. The review of the driver monitoring systems aimed to identify whether the current safeguards would be adequate to control the risks associated with the proposed operations or whether additional measures would be required.
