SRAM RDM Release Notes – Version 2.0
This document outlines the latest updates and capabilities of the Strategic Rail Analysis Model (SRAM), developed by Network Rail’s System Operator team. SRAM integrates Great Britain’s rail infrastructure, timetables, and public transport networks to simulate rail passenger demand at a national scale. The model supports rail and integrated transport supply analysis, demand forecasting, and service benchmarking. Key enhancements in this version include improved temporal demand distribution, bus-rail synchronisation analysis, and data publication on the Rail Data Marketplace (RDM). Future updates will refine demand calibration and enhance model accuracy with additional real-world data sources.
SRAM RDM Data Quality Statement – Version 1.0
This document provides an assessment of the data quality used in the Strategic Rail Analysis Model (SRAM), developed by Network Rail’s System Operator team. SRAM integrates national rail infrastructure, public transport schedules, and demand data to model rail passenger flows across Great Britain. The report outlines key data sources, including rail timetables, public transport networks, sensor-based demand calibration, and mobile network data. It also evaluates the accuracy of model outputs, such as station and service demand levels, journey times, and connectivity scores. Future updates will refine demand estimation methodologies and enhance data precision through improved calibration and validation techniques.
