Highlights Freight trips are modeled as a joint package consisting of outsourcing and insourcing decisions. Multivariate modelling framework is used to account for error correlations between freight trips. Substitutive relationship found between insourced and outsourced trips using same truck type. Models reveal the exogenous effects of busines size, age, fleet ownership and industry sector. Study findings highlight the drawbacks in the current approach of modelling overall freight trips.

    Abstract Despite the advancements in the logistics choices, freight trip generation (FTG) studies in the past have made no distinctions between insourced and outsourced variants of trips and the associated selection of truck types. This paper addresses past research gap by treating FTG as a joint package decision and proposing a multivariate ordered response system that allows error correlations capturing the underlying interdependencies. Study findings reveal the presence of complementary and substitution effects between freight trip decisions, and the additional computation burden resulting from the simultaneous model estimation appears to be justified for improving the logistical foundations of FTG models.
