Query: Impacts of Covid-19 mode shift on road traffic   This article is driven by the following question: as the communities reopen
after the COVID-19 pandemic, will changing transportation mode share lead to
worse traffic than before? This question could be critical especially if many
people rush to single occupancy vehicles. To this end, we estimate how
congestion will increases as the number of cars increase on the road, and
identify the most sensitive cites to drop in transit usage. Travel time and
mode share data from the American Community Survey of the US Census Bureau, for
metro areas across the US. A BPR model is used to relate average travel times
to the estimated number of commuters traveling by car. We then evaluate
increased vehicle volumes on the road if different portions of transit and car
pool users switch to single-occupancy vehicles, and report the resulting travel
time from the BPR model. The scenarios predict that cities with large transit
ridership are at risk for extreme traffic unless transit systems can resume
safe, high throughput operations quickly.
