Is it possible given only the traffic flow from each cell of grid estimate the origin destination demand? #26

I have the traffic flow of each cell of grid 8x8 a priori, Given only the traffic flow from each cell of the grid, is it possible to estimate the origin-destination demand?

How to call the methods or functions to obtain the ODs?
