Abstract

Abstract: In order to control spread of infectious diseases in motor vehicles, their transmission mechanism and influencing factors were studied by using infectious disease transmission model. Based on theory of infectious disease dynamics and by introducing concept of virus transmission density, SIR model of infectious diseases in buses and small private cars was established considering transmission mode of COVID-19 and driving characteristics and transmission environment of motor vehicles. Then, the model under different driving conditions were studied through numerical simulation analysis and comparison. The results show that virus transmission in cars can be suppressed during outbreak of epidemic by adopting strategies, like reducing driving time and people exchange frequency, enforcing ventilation and disinfection, and making appropriate choices for bus and private car travel according to preventative and control environment.

Key words: transmission of infectious diseases, susceptible infected recovered (SIR) model, motor vehicles, buses, small private cars, corona virus disease 2019 (COVID-19)
