Research On The Evolution Mechanism Of Travel Mode Of Urban Village Residents Under The Background Of Urban Renewa

Urban villages are a product of the urbanization process in China.Compared to urban communities,they have dense building patterns,higher population densities,these result in different travel characteristics of urban village residents compared to those of urban community residents.In recent years,with the advancement of urban renewal policies,more and more urban villages are undergoing renovation.Understanding the evolution mechanism of trip modes of urban village residents is of great significance for the rational allocation of transportation facilities,facilitating resident travel,and promoting sustainable development of urban transportation during the urban village renewal process.Therefore,this study focuses on the differences in trip mode choices between urban village and renovated community residents,explores the mechanisms of trip mode evolution of urban village residents under the background of urban renewal,and provides theoretical support for the implementation of urban renewal.This paper selects nine typical urban villages and four renovated communities in Tianhe District,Guangzhou City as research objects.The RP survey method is used to investigate the travel behavior of residents in the two types of communities.The individual travel characteristic evolution of urban village and renovated community residents is analyzed from three aspects:personal attributes,household attributes,and travel characteristics.Then,the spatial syntax axis model of Tianhe District is established to analyze the evolution process of spatial structure of the road networks in these two types of communities.Subsequently,POI data and public transportation data are crawled by using Python and Baidu Maps API,respectively,and Arc GIS is used to analyze the evolution of the built environment within a 1500 m buffer zone of the two types of communities.On this basis,the Pearson correlation test is used to optimize the travel influencing factor system.The key factors affecting motorized trip(cars,subways,buses)of residents in renovated communities are extracted by factor analysis and compared with those of urban villages.Finally,based on the principles of system dynamics,and combined with the analysis of individual trip and built environment evolution characteristics,a theoretical model of the evolution mechanism of travel modes of urban village residents is constructed,and the actual survey data is used to test the model.This paper found that the renovated communities have many changes compared to urban villages as follows: the proportion of residents owning their own homes has increased,the overall cultural level of residents has improved,the income level is generally higher than that of urban village residents,the proportion of households owning cars has increased,and the supporting transportation facilities in renovated communities are more complete.These factors will affect the choice of trip modes of residents in renovated communities,and there are inherent relationships between them.The system dynamics model can establish the relationships between these factors.The spatial structure of road networks is a significant factor influencing residents’ choice of trip mode.The axial density,integration degree,and connection value of renovated communities are lower than those of urban villages.This encourages residents in renovated communities to choose cars for trip and reduces their use of public transportation.This study suggests that during the renovation process of urban villages,it is advisable to optimize the built environment and improve connectivity with public transportation to increase its attractiveness and reduce the proportion of trips made by residents in private cars,guiding them towards green travel.
