Abstract

We investigate 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.
