Citymappper provides very interesting data to see how public transit in cities is changing due to COVID-19 - some is gov't policies, some is just people choosing to work from home. Can be helpful in understanding timing of global trends
Citymapper Mobility Index
We are comparing trips planned in the Citymapper app to a recent typical usage period. Trips planned ('Get me somewhere' and related) are correlated to trips taken (GO mode). We have enough data in our cities where we publish CMI to be confident that it represents a real change.
