| The impact of urban built environment on residents’ travel behavior has gradually become a hot topic in the field of traffic behavior analysis.In the context of the normalization of epidemic prevention and control,there is a clear difference between the short-distance travel behavior of residents in residential areas and the long-distance travel behavior such as commuting,and whether the built-up environment has an impact on the short-distance travel behavior of residents becomes the main issue of this research.First,considering the normalized scenario of epidemic prevention and control,the irrational modeling of the theory of planned behavior and the adaptability of short-distance travel to the SOR theory,this research integrates the theory of planned behavior with the SOR theory and considers the social environment latent variables in the previously studied built environment.We build a platform based on Amos to construct a model of the influence of the built environment on residents’ short-distance travel during the normalization of epidemic prevention and control through structural equation modeling.Secondly,this research designs a survey questionnaire to collect data according to the constructed model,which is subjected to repeated sampling,multiple reliability testing,and descriptive statistical analysis of the data.Through the survey,we found that the respondents believed that the built environment can influence the travel demand,and the willingness of men is stronger;the proportion of a certain travel mode is close to different urban area types;the frequency of new urban areas and old and new mixed urban areas remain consistent with the increase of travel time,while the frequency of travel in old urban areas slightly decreases with the increase of travel time.Again,to solve the problem of cardinality inflation caused by the large sample of questionnaire data,this research adopts the Bollen-Stine method based on repeated sample sampling to modify the model parameters,and analyzes the mediating and moderating effects of the built environment and social environment elements in the constructed structural equation model according to the double mediation model and the two-stage interaction method.Finally,this research provides a theoretical basis for the formulation and improvement of travel policies related to the residents of Harbin city during the normal period of epidemic prevention and control based on the model calculation results and the relationship between the built environment on the characteristics and influence of short-distance travel behavior,and provides suggestions and recommendations for their rational travel and the built environment for improvement.This study can provide theoretical support and specific suggestions for prevention and control at the transportation level and the built environment level in the context of large public health events,and can improve the ability and level of response to major public health events. |
