Abstract

Two approaches can be used to represent a transit system: the line approach where all runs belonging to the same line are simulated in a single infrastructure line; the run approach where the single runs are explicitly simulated. Assignment models simulate how origin-destination demand flows affect link flows and resulting performance. Traffic assignment models in transit systems are generally made up by two different h4. Approaches: a hyperpath strategy approach for high frequency systems or strategic level and considering a line approach for supply; a diachronic strategy approach for low frequency systems or operative and tactical level and considering a run approach for supply. In this paper the diachronic strategy approach for low frequency systems and the hyperpath approach are applied and compared in the extra-urban supply system of Reggio Calabria (extraurban administrative district of Reggio Calabria). In the district there are about 570,000 inhabitants and the supply consists of 1344 runs a day. The results obtained are discussed and are used to evaluate serviceintegration and costs and revenues.
