Study of Aerosol Movement and countermeasures in public transportation

Public transportation is required to have effective measures against the new corona infection. In this study, the authors investigated the actual condition of ventilation, which is said to be the infection route of the virus, and examined the countermeasures in addition, the behavior of the particles when they were diffused into the route bus was measured. PSL and artificial saliva were used as the particles. PSL tends to be deposited easily, so the particle concentration is too low. It may lead to evaluation. Also, the particle collection ability of the aerosol filter was evaluated. From this result, it was found that it has the same effect as window opening ventilation.
