Analysis of the influence of traffic control measures on the prevention and control of COVID-19

Abstract

Transportation plays an important medium role in the COVID-19 epidemic spread, and correctly understanding this role will help to prevent and control the epidemic spread among different areas. This paper analyzed the process of the COVID-19 epidemic spread through transportation channels at home and abroad, and made a comparative analysis of the epidemic development before and after taking traffic control measures in different countries around the world. After clarifying the role of transportation channels in the epidemic spread, we simulated the epidemic development under different traffic control measures based on the SEIR disease dynamics model. The results show that, without traffic control measures, the peak value of infected people will appear earlier. If strict traffic control measures are taken, the simulated lines of the latent and infected people will almost disappear, and the epidemic will soon stop. Our research results provide a theoretical basis for formulating reasonable traffic control measures.
