Details
This guidance provides advice on the development of variable demand models. This covers scoping the need for such models, their specification, development, calibration and validation, and ensuring fitness for purpose in forecasting.
It also provides guidance on developing demand matrices for the modelled base year. This covers methods for gathering matrix data, treatment of the data, and combining of data from different sources to develop and explain the quality of base year demand matrices.
