This study examines the vehicle choice behavior of multicar households for different travel accompanying arrangements. It investigates the influence of various travel attributes and neighborhood characteristics to understand how individuals in a multicar household make a choice of vehicle for a specific travel arrangement. The study considers three types of travel arrangements based on accompanying persons (i.e. alone, with household members and with non-household members) and categorizes households’ vehicle fleet into six classes: subcompact, compact, midsize, SUV, vans/minivans/pickup-trucks and luxury vehicles. Three flexible latent class logit models (LCLMs) are developed in this study to estimate vehicle choice decisions by utilizing data from the ‘2015 Nova Scotia Travel Activity (NovaTRAC) survey’. Results suggest that individuals tend to prefer subcompact vehicles and SUVs for longer travel time while traveling alone and with non-household members, respectively. They show higher likelihood to choose midsize vehicles for long-distance trips when traveling with household members. The behavioral models also capture unobserved heterogeneity across population by developing flexible class allocation models within LCLM frameworks that probabilistically distribute individuals into discrete latent classes based on their socio-demographic characteristics. Model results intuitively suggest two latent classes for all three travel arrangements and explore heterogeneity across classes. Results of this study will assist the transportation planners and policymakers to develop alternative transportation demand management strategies that aim at reducing vehicular emission and energy in a traffic network.
