2016 - 2017 Weather-induced single point of failure assessment methodology for railways (PI: Funded by NERC Environmental Risks to Infrastructure Innovation Programme: £67k)
This project aims to produce a transformative data-driven approach to map the criticality to weather-induced natural hazards as a fundamental step in both improved extreme event management and climate change adaptation prioritisation. Key to this is an expert-led metric for network criticality which can be used to identify the most critical locations on the network. This help inform where adaptation work will have optimal benefit, whilst also aiding the allocation of resources and operational decisions during extreme events, reducing disruption-related costs and improving service to customers. The project has the following objectives:
1. Define the key determinants of criticality from Network Rail's perspective.
2. Formulate a criticality metric based on the identified determinants
3. Demonstrate the metric on a Network Rail route and identify network-critical sections of track.
4. Elicit views on implications for adaptation actions and extreme event management.
