Traffic velocity control for evaluation the impact of gases emissions: Case study of toll plaza

The purpose in this paper is to evaluate the impact of CO2 emissions from traffic in interurban area. Initially the main idea was to apply control strategy on the road under the assumption to assure fluid traffic flow. In the following the gases emissions was evaluated as results of this regulation procedure. The proposed control approach is based on noninteger robust methodology. Therefore, is possible to analyse the speed and density variations due to perturbations on the road and to assure robust performances for the traffic velocity. The pollution factor of CO2 emissions of the controlled and uncontrolled model was evaluated and compared. The chosen study case is macroscopic traffic flow model, situated downstream on a toll plaza. The method of modelling traffic flow at macroscopic level is based on the assumption that the whole traffic stream is comparable to fluid stream. The motion law of vehicle and his full fuel combustion equation are presented. Then the models of the traffic with the CO2 emissions, for all the traffic streams, were combined. The control of the traffic situated downstream on a toll plaza scenario has been designed. Based on simulations, the robust performances of the parameter variations and their influences on the CO2 emissions were evaluated.
