- Abstract
- This study analyzed the impact of COVID-19 on traffic speeds, focusing on the Gyeongsangbuk-do region. Data on traffic speeds by road were collected annually from 2020 to 2023 in February, examining the correlation between the social distancing levels due to COVID-19 and traffic speeds. The Gyeongsangbuk-do region was divided into Daegu zone, Gumi zone, Pohang zone, and Andong zone to examine the industrial impact of COVID-19. In 2021, when the social distancing level was at level 3, the fastest traffic speeds were observed in all regions. Comparing the traffic speeds in 2023, as preparations for returning to daily life were underway, showed an increase in traffic speeds by 6.7% in the Daegu zone, 5.3% in the Andong zone, 11.4% in the Gumi zone, and 10.1% in the Pohang zone. Despite some impact on service industries, the consumer-oriented Daegu zone experienced relatively minor changes in average traffic speed. The Andong zone, with its family-oriented agriculture and livestock industries, experienced a comparatively minor change in average traffic speed due to less impact from social distancing measures. In contrast, the Pohang and Gumi zone, known for their manufacturing and heavy industries, experienced a rapid increase in traffic speeds due to decreased traffic volume resulting from factory closures during social distancing and self-isolation measures.
