Evaluation of O/D trip matrices by traffic counts transport systems. An application to a real case

The paper deals with the Origin/Destination (O/D) trip matrices estimation in transit systems using traffic counts. The methodology allows both the correction and improvement of the global demand level and the updating of the demand model parameters. An application is executed for the sub-regional area of Reggio Calabria (Italy), and the transit network is modelled by both frequency-based and schedule-based approaches. The results concern the estimation of the average level and the temporal distribution of the daily demand for the bus and train sub-systems, the improvement of an initial set of modal split demand parameters.
