With the coronavirus pandemic, a unique scenario was created where a visual approach could show how drastically speeds throughout the day have changed. Due to its potentially high infection rates, the state closed public buildings such as schools and offices on March 18, 2020 and issued a stay at home order on March 21, 2020. With this, a unique event in transportation occurred, where a statewide unplanned sustained event suddenly changed traffic volumes. Because of its sudden nature, speeds could be compared around a turning point, March 18, where speeds before could be compared to speeds after. Alongside a quantitative analysis of the probe vehicle speeds, speed distributions could be applied to visualize how typical morning and afternoon peaks have changed before March 18th, to after.
