Accounting for similarities in destination choice modelling: A concept

Abstract

Modelling the choice of destinations or activity locations is a crucial step in the analysis of transport behaviour.In real life, the decision makers' choices are highly complex and influenced by several factors such as the attributes of the destination itself, its accessability by different means of transport, the location of preceding or subsequent activities, or the attributes and accessability of competing destinations.In the traditional four step model, a lot of these factors have been ignored or only accounted for by rough approximations.State of the art transport models aim to overcome these shortcomings in different ways.Activity-based models incorporate trip chaining and accessability effects while classic discrete choice modelling focusses on capturing correlations between alternatives by developing more advanced model structures or similarity factors for individual attributes.This paper presents a general framework for the treatment of similarity in a discrete choice model for destination choice of secondary activities.The framework combines several aspects of similarity derived from spatial location, the journey to and from the destination, trip chaining restrictions, and the attributes of the alternatives themselves.Moreover, it is applicable a simultaneous route, mode and destination choice model.
