Epidemic Prevention Mode of Elevated Pedestrian Network

In the past few years, public health and street space design are receiving extensive attention.The study have shown inhalable particle and gaseous pollutants exposed in outdoor spaces directly or indirectly affect population mortality，hospitalization rates and respiratory disease symptoms and other issues in the field of public health. As an important activity place for urban residents, the air quality of urban streets is closely related to residents' health.In the context of global epidemic prevention and control, this article takes the elevated pedestrian system in the street form as the main research object, focusing on the positive impact of its spatial controllability on the spread of the epidemic, street air pollution and other public health issues, and sorts out cities at home and abroad Street space design cases and guidelines address the improvement methods of public health issues, analyze the feasibility of its application in elevated pedestrian systems, and further propose response strategies for different public health issues, so as to enhance happiness, develop knowledge economy and service economy for the guidance, the public space organization mode and design method of the elevated pedestrian system are proposed in combination with public space and commercial service facilities. Connecting the existing commercial and public facilities the elevated pedestrian system will form the major residents activity layer.
