The Effect of Trust on Driver's Response to Advanced Driver Assistance System and Its Affecting Factors: A Case Study of IMA

Abstract

This study was conducted to explore the role of trust on driver's reacting behavior when an alert is triggered by the intersection movement assistance (IMA) system, based on data collected from 26 participant vehicles equipped IMA under real field operation as well as questionnaire design and survey. Moreover, some important factors related to trust were measured, in order to develop a model to realize the principle about how drivers establish and modify their trust. The study results show that driver's reacting behavior has positive correlation with trust in IMA. The trust before using IMA has positive correlation with expected usefulness and mental model, and the trust after using IMA has positive correlation with perceived usefulness and expectation confirmation. The study results are expected to illustrate the effect of the trust and provide some suggestions based on the principle of how trust develops
