Abstract: In recent years,online car-hailing service has been developing rapidly.However,safety problems hidden in its operation is becoming increasingly prominent.In order to study safety perception of passengers,this paper illustrates safety problems from three perspectives using a fishbone diagram:traffic safety,information safety,and personal and property safety.Based on it,a questionnaire survey is designed and conducted.In order to present complex relationships between different latent variables,a logical framework based on structural equation model (SEM) is developed,which reveals influencing paths and significance of personal characteristics,accident experiences,safety knowledge,and risk propensity on safety perception of online car-hailing passengers.The results of SEM indicate that accident experiences,safety knowledge,and risk propensity of passengers have great influences on safety perception when they have online car-hailing.Personal characteristics such as gender and income also have impacts.The results can provide theoretical references for policy-making on safety management of online car-hailing.
