The main objective of this paper is to propose a new two-class macroscopic emission model to describe the pollutant emissions produced by freeway traffic. The innovative aspect of the proposed model consists in considering the on-ramp emissions, which are explicitly modeled for different traffic scenarios. Next, a two-class local controller based on a ramp metering is reported with the aim of minimizing emissions and congestion in the freeway system. The relevance of the on-ramp emission model is in this way highlighted, since ramp metering may lead to creation of queues at the entering on-ramps and hence a concentration of pollutants on these on-ramps. Simulation results show the effectiveness of the proposed control strategy for a case of study.
