A Note on the Consistent Aggregation of Nested Logit Demand Functions

This paper presents a method of constructing travel demand functions of a sketch-planning model. A set of rules is derived allowing for the consistent aggregation of nested logit travel demand functions across origin and destination zones. Presented aggregation rules are derived for the case when the mode choice is performed conditional on destination choice. The derivation is based on consistency principles, introduced by Sweet (1997) for aggregating logit demand functions across choice alternatives, as well as upon the sampling theory. The proposed formulas provide consistence between the results of a large elaborated transport model and the corresponding small sketch-planning model, in terms of generated travel demands. The proposed method may also be used in cases where a choice set is large and a compact model would be more tractable.
