Human reliability analysis plays an important role in the safety assessment and management of rail operations. This event will present how the increasing availability of operational data can be used to develop an understanding of train driver reliability.  Two driving tasks will be looked at: stopping at red signals and controlling the speed of a train on approach to buffer stops.  The event will present practical examples of how big data could play an increasingly important role in system error management, whether from the perspective of understanding normal performance and the limits of performance for specific tasks or as the basis for dynamic safety indicators which, if not leading, could at least become closer to real time.

This will be a joint face-to-face meeting at RSSB’s Offices in Moorgate, London and an online webinar.

The event will be co-presented by Chris Harrison, Futures Lab Systems Engineer , Rail Safety & Standards Board (RSSB) and Xiaocheng Ge, Senior Risk and Safety Intelligence Analyst, RSSB.

Chris started his career in 2000 as a Safety Analyst for the National Air Traffic Services (NATS) working on modelling the risk from a mid-air plane collision. In 2003 he joined the Rail Safety and Standards Board (RSSB) as a risk analyst where he was set to work on developing and maintaining the Safety Risk Model (SRM), the GB rail industry’s network wide model of safety risk. He is currently working as a Futures Lab Systems Engineer at RSSB, helping to identify the challenges and opportunities the rail industry may face and how to be ready for them. As well as being a Fellow of SaRS, he is currently SaRS Chair-Elect and the Editor-in-Chief of the SaRS peer reviewed journal Safety and Reliability.

From 2002 to 2016 Xiaocheng was a research fellow and lecturer in the High Integrity Systems Engineering Group, at the Department of Computer Science, University of York. He joined the Institute of Railway Research, University of Huddersfield in 2016. During those years, his research mainly focused on the safety assessment methodologies and safety arguments. Since 2017, he has been collaborating with Chris from RSSB to develop the Red Aspect Approaches To Signal (RAATS) toolkit. In 2021, he joined RSSB, and is currently a Senior Risk and Safety Intelligence Analyst in the Risk and Safety Intelligence team.
