标题：Investigating the association of psychological impacts of delay on the perceived importance of real-time information: three-stage least square instrumental regression
摘要：Abstract This study was conducted to evaluate the association between psychological impacts of delay on commuters and three indictors of the rail transport real-time information. The case study experienced sporadic long delay and simultaneously imprecise real-time information. Three dependent variables related to the passenger information system (PIS) were modeled simultaneously, including perceived waiting time, satisfaction, and the quality of rail transport. Given the likely correlation between the considered models error terms, the relationship between dependent and the independent variables was modeled with the three-stage least square (3SLS) model. We found, for instance, that there are significant association between the impacts of the real-time information and commuters’ gender, purpose of travel, frequency of travel, and various psychological feelings that commuters experienced. However, interaction results highlighted that the associations between experienced negative emotions and dependent variables are not stable but vary based on other predictors. For instance, the association between purpose of travel and increased satisfaction due to accurate real-time information varies based on the frequency of using the transport by commuters. Also, the association between feeling frustrated and increased perceived time due to imprecise real-time information differs based on the amount of anger the commuters experience due to delay. In summary, we found that commuters who experience a higher level of negative feelings are expected to assign a higher importance to the accuracy of real-time information, but those effect are varied based on their purpose of travels or other demographic characteristics.
