Does anyone know of any datasets around interstate travel?

Does anyone know of any datasets around interstate travel? Feel free to comment in thread, DM or email at mailto:charity.hilton@gtri.gatech.edu|charity.hilton@gtri.gatech.edu. Thanks!

I suspect the data here might be useful: GitHub - COVIDExposureIndices/COVIDExposureIndices: Exposure indices derived from PlaceIQ movement data by Couture, Dingel, Green, Handbury, and Williams

@Kosali_Simon_Indiana_University may have some useful pointers in her paper from the other day

Thanks @Martin_Andersen_UNC_Greensboro - I will check it out
