If officials ease these restrictions gradually, this data could help them gauge the effect and find the best point of tradeoff between being overly restrictive and being in too much of a hurry to reopen. It's going to be a balancing act to open things up again without reintroducing the rapid virus spread that sent us all into hiding in the first place. I expect to see a second bump in the curve, and the trick is to keep that bump from exceeding health services by proceeding at the right pace.Like what, it’s clear if people are forced to work from home, public transport doesn’t run and people get fined if using cars, the number of people moving around will be lower.
The data could also be used to compare the effectiveness of policies among cities.
