Planet Framework Model (PFM V4.3): Model Description

An overview of the Planet Framework Model, which was used to forecast the demand and benefits of the High Speed Two rail network.



The aim of this document is to provide a clear account of the Planet Framework Model (PFM V4.3). It brings together a large amount of information which has previously been separately reported, often only in working notes, and therefore constitutes an authoritative description of the model at a particular stage in its development.

‘HS2: Planet Framework Model development’ describes the evolution of the model.
