Abstract

Insufficient supply and inferior quality of public transportation in developing countries yield a greater impact on vehicle-ownership and usage. Although there is a substantial increase of vehicle ownership in such countries, maintaining multiple vehicles within a household is not very practical. Therefore, limited availability of vehicles has to be effectively utilized for all travel-related daily activities in a household. Consequently, the vehicle user, most commonly the commuter, has to get the responsibility of driving for other household members. Finally, a direct commuter trip has been drastically changed into a frequent multipurpose trip. In general, a trip chain with multiple household members creates numerous intermediate stops and purposes. However, it has to be sufficiently flexible to satisfy all travelers’ requirements with minimum deviation of commuters’ travel schedule. This study aims to develop a multi-level nested logit (NL) model to analyze the household decision on vehicle-ownership, and associated effects on trip chaining in developing countries. More specifically, emphasis is made on trip chaining behavior of households rather than investigating trip chains that are created by individuals. The nesting structure represents the choices of vehicle-ownership, vehicle selection and mode selection for two-traveler households. Household serving chain is incorporated as one of the mode-choice options in the developed NL model. The model verification uses the person trip survey data from Bangkok Metropolitan area.
