the problem of finding the
Origin-Destination trip matrix in a roundabout at optimal cost.
The goal is to choose the turning movements that will be measured in
addition to some independent total volumes at exits, entries and
cross-sections inside the roundabout. Three cost criteria are proposed,
each one modelling the cost of data collection in a different way.
We discuss aspects of our study of this problem on computer
and go through
interesting mathematical properties
we have found the proposed model to have.
