The U.S. Department of Transportation (USDOT) needs to respond quickly and adapt to the coronavirus (COVID-19) to ensure continuation of critical infrastructure support and relief for the American people. Since early March 2020, the COVID-19 pandemic has had significant impact on traffic across the United States. It is clear to see that traffic patterns, traffic demands, and duration alter with COVID status. Therefore, there is a critical research need to study the impact of COVID on traffic patterns and to analyze the relationships among traffic demand patterns, daily confirmed cases/deaths, state policies, public perceptions, etc. In this research, we investigate the impact of COVID-19 on traffic safety in different stages, focusing on Salt Lake County, Utah. Statistical methods are employed to determine if there are any differences in the effects of the pandemic. Further, the effect of COVID-19 on traffic patterns in Salt Lake County and Utah County from January 2019 to July 2021 was analyzed. Different vehicle miles traveled (VMT) patterns in the pre-pandemic stage, early stage of the pandemic, and late stage of the pandemic are identified. Finally, a knowledge-based traffic prediction model utilizing an innovative approach that integrates machine learning with graph theory is proposed to forecast traffic patterns in the near future.
