A model to evaluate heavy vehicles effect in motorway traffic flow

Research output: Contribution to conferenceOther

Abstract

Highway operating conditions are also determined by interactions between passengercars and heavy vehicles in the flow. Therefore, a suitable model which describes and predicts the heavyvehicle effect can be useful to achieve more realistic criteria to evaluate the Level of Service (LOS) forinfrastructures in the uninterrupted flow. After reviewing briefly the models available in literature totake account of the effects on operating conditions due to heavy vehicles, the paper examines some trafficdata analysis of the Italian A22 motorway and later presents a closed-form traffic model for heavyvehicles via the queuing theory. Some applications of this model are displayed for operational purposesand a critical evaluation of the results is also made in comparison with some experimental evidence.
