We analyzed the relationship between the step counts and traffic safety indicators by the multiple regression analysis. Results show that residents, especially older adults, in areas with many pedestrian streets, high proportion of multilevel intersections and high proportion of three-way intersections tend to walk more. In addition, these traffic safety indicators are found to be significantly more common in planned residential areas, especially in large-scale developments and developments by public entities. In conclusion, this study evaluates the pedestrian friendly designs in existing planned residential areas and suggests the need to actively preserve and utilize these designs in future residential development.
