Practical Origin-Destination traffic flow estimation

We present an application implementing an original trafc ow simulation and forecast model for the road network of the Forl-Cesena province. We dened and calibrated a model, which makes use of trafc counts collected on some network arcs, of an origin/destination (OD) matrix of the province and of physical characteristics of networks arcs, and permits to identify trafc ows compatible with actual counts. This same model, after the calibration of its parameters for the province network, has also been utilized for forecasting new ows following structural variations of the network. The application also contains an OD matrix renement module which permits to update matrix entries as a function of the actual trafc counts.
