a commodity level, in which the freight O/D matrices in quantity are estimated from socioeconomic data; a vehicle level, in which quantity flows are converted in order to obtain O/D matrices in vehicles (e.g. trucks or lorries).
A more practical idea might turn out to be a Daedalus proposal to use the "junk DNA" incorporated in the genomes of all living creatures, including microbes, as a vehicle for storing vast quantities of information.
This enabled the researchers to know, for example, the precise arrival and departure time of vehicles as well as vehicle type and product quantities delivered.
