Abstract: For the problem that variable message signs (VMS) cannot release information in time and reasonably induce the driver's route choice in traffic accident area, in this paper, SP+RP questionnaire was used to investigate drivers' subjective perception of socio-economic characteristics and travel characteristics, the subjective impact of travel time on drivers' route selection and the results of drivers' choice under two types of traffic information combination schemes. The structural equation models (SEM) of drivers' willingness to accept traffic information schemes were constructed. Results shows that the driver's driving age, travel purpose and travel time limit are the key factors that affect the driver's subjective perception and willingness to accept the combination of traffic information. In SEM of drivers' willingness to accept VMS traffic information combination schemes, the influencing coefficients of drivers' willingness to accept the combination of traffic information with travel time restriction are 0.678 and 0.769, respectively, while those without travel time restriction are 0.435 and 0.390, which indicates that drivers with travel time restrictions have a stronger willingness to accept the combination of traffic information than those without travel time restrictions.
