Dynamics of information generation and transmissions through a social network in non-recurrent transport behaviour

摘要

Travellers attempting to make a non-recurrent trip cannot rely on their own experiences and, consequently, must rely oninformation generated by others. In such situations, travellers’ choices are subject to information transmissions through a socialnetwork; if this does not work well, they fail to make efficient choices owing to lack of information. This study proposes a modelthat describes the dynamics of information generation and transmissions and conducts an analysis to investigate the conditionsthat allow travellers to make efficient choices. It is shown that suppressing rapid diffusions of information and encouragingintentional searching for information can help travellers to make efficient choices.
