Scope
Description
The aim of T1398 is to generate and apply the methodology needed to prioritise and make the case for interventions to make boarding and alighting more accessible.
To achieve this, the project will:
•Define a range of Boarding Categories based on PTI geometry data and human factors. The thresholds between these categories should be driven by the proportion of passenger persona groups who can board independently and safely.
•Assign platform/train pairings across the network to the Boarding Categories, determining the most appropriate way to capture each pairing given multiple points along the length of platform and multiple doors on trains. This will deliver an understanding of the distribution of actual platform/train stepping arrangements across the categories. This insight must be presented in a way that enables industry to prioritise action and consider solutions for improving stepping arrangements.
•Develop a benefit-assessment methodology to assess the value (financial, economic, and societal) resulting from removing the less accessible arrangements from the GB network or partially improving them (e.g. allowing for one carriage of a train to have level access).
