Savi Rail Performance Model

The Savi Rail Performance Model (SaviRPM) is a sophisticated simulation and performance modelling application originally developed as part of the RSSB and Network Rail funded Sandbox research programme. It was developed by Risk Solutions with the help of rail industry partners.

SaviRPM enables performance teams to generate better understanding and management of performance and capacity risk, using cutting edge methods including: big data analysis, agent based modelling, and interactive visualisations.

SaviRPM provides a powerful strategic decision tool helping train operating companies and Network Rail identify where there are potential risks to performance, and remove system fragility from timetables and service operation, creating a more robust and resilient system to improve service performance for passengers and freight customers.

SaviRPM is an agent-based model and has been designed to play out the interactions and potential conflicts between all rail services across a relatively large geographic area, and how they perform when suffering from typical delays. Many simulation runs create a distribution of service performance, from good days to bad days. Exploring these results using Savi’s interactive visualisation tools provides insights into the root causes of poor performance and how these can be tackled. SaviRPM is also used by performance teams to model proposed solutions to improve performance, reporting the likely service performance improvements.

This visualisation of SaviRPM results provides a way to compare the performance of alternative interventions to improve services.

Map View

This interactive map visualisation is used to identify where delays to train services are occurring, so that rail performance teams can design targeted interventions that improve performance.

Train View

This interactive visualisation is used by rail performance teams to find the trains that are causing the most delay to passenger journeys, so that they can design targeted interventions to improve performance.

Timetable View

This visualisation has been developed in close collaboration with Network Rail to test changes to timetables, and highlight any risks to exceeding network capacity.
