- Abstract
The urban built environment is closely related to the occurrence of traffic accidents. Accurately identifying the spatial heterogeneity characteristics of factors affecting traffic accidents is of great significance for accurate traffic safety management and control. In this study, 2,114 Traffic Analysis Zones (TAZ) in Tianjin, China were used as the research units, 25,869 road traffic accident data were collected as the dependent variable, and 12 built environment density data such as roads and Point of Interest (POI) were extracted as independent variables. After confirming the spatial dependence of the data based on the spatial autocorrelation test, three spatial econometric models of Ordinary Least Squares (OLS), Geographically Weighted Regression (GWR), and Multiscale Geographically Weighted Regression (MGWR) are constructed for optimization analysis. The research results show that MGWR is the optimal model to describe the spatial heterogeneity of traffic accidents in different built environment factors. There is a negative correlation between recreational density and intersection density with traffic accidents, while other influencing factors show a positive correlation. The regression coefficient for retail industry density is significantly higher than other influencing factors, while the regression coefficient for leisure and entertainment density is significantly lower than other influencing factors.
