Commute Traffic Mode Choice Based on Structural Equation Model

Previous traffic mode researches are mainly based on the influences of individual characteristics to the traffic mode choice,and researches on the correlation analysis of different kinds of individual specialties and different traffic mode features are very limited. Taking the medium and long distance commuters as subjects,a structural equation model was built in this paper by extracting selective parameters of individual specialty and traffic mode features. Meanwhile, interactions between the individual specialties and the traffic mode features of public transportation or self-driving were analyzed,and then the direction and degree of all effective factors and the public transportation willingness were captured. Results show that individual economic level has essential effect on the traffic mode choice. Less walking time after parking,lower parking fee and abundant parking spaces encourage people to commute by car. However,the public transportation attraction increases by reducing the waiting and transfer time,and improving the running speed. This paper has significance for policy makers in urban area who encourage people to travel by public transportation.
