As such, results of Table 1 show that the relations between air traffic restriction and the existing cases, and the recovery rate of COVID-19 are not linear. Since the real-time data regarding car, bus, and train are not available, the impact of land transportation restriction on the existing cases and recovery rate of COVID-19 cannot be examined. With the availability of real-time data of land transport, future research can make a comprehensive investigation on policy effectiveness of traffic restriction in containing the spread of infectious diseases. ./cache/cord-353735-d81ujjxv.txt ./txt/cord-353735-d81ujjxv.txt
