Random regret minimisation and random utility maximisation in the presence of preference heterogeneity: An empirical contrast
Published 2015-04-01Random regret minimisation (RRM) interpretations of discrete choices are growing in popularity as a complementary modelling paradigm to random utility maximisation (RUM). While behaviourally very appealing in the sense of ...Open AccessWorking Paper -
A lossless spatial aggregation procedure for a class of capacity constrained traffic assignment models incorporating point queues
Published 2015-11-01In this paper two novel spatial aggregation procedures are proposed. A network aggregation procedure based on a travel time delay decomposition method and a zonal aggregation procedure based on a path redistribution scheme. ...Open AccessWorking Paper -
A simplified and practical alternative way to recognise the role of household characteristics in determining an individual’s preferences: the case of automobile choice
Published 2015-05-01It is common practice in choice modelling to include the socioeconomic characteristics of other members of a household in the utility expressions associated with the preferences of a particular individual. By including ...Open AccessWorking Paper -
Detecting dominancy and accounting for scale differences when using stated choice data to estimate logit models
Published 2015-08-01Stated choice surveys have been used for several decades to estimate preferences of agents using choice models, and are widely applied in the transportation domain. Typically orthogonal or efficient experimental designs ...Open AccessWorking Paper -
Frequency‐based transit assignment revisited
Published 2015-09-01This working paper reformulates the Spiess and Florian frequency-based transit assignment method in matrix algebra revealing a new solution method. It is shown that the number of destination-specific passenger wait times ...Open AccessWorking Paper
