This paper presents an expanded and generalized formulation of discrete group decision-making model. The empirical model is developed for modelling high school student escort and travel mode choices. The development of the model uncovered issues with an existing group decision model, the multi-linear logit, that has recently been applied to similar decision contexts. The paper proposes an expanded formulation of parallel constrained choices logit model as an alternative to the multi-linear logit. The proposed model explicitly considers both the choice of mode of the students and commuting adults within the household and how those decisions change in response to household escort decisions. The model is generalized such that any number of adults can be accommodated within the modelling structure whereas previous studies have been limited to either two adults or two workers. The key findings of the analysis include a certain degree of altruism (or dedication) from adults to household children, which is captured indirectly within the modelling framework based on a lower weight for the adults in the household relative to the children.
