A nonlinear optimal control approach for two-class freeway traffic regulation to reduce congestion and emissions

The research leading to these results has received funding from the European Research Council under the European Union's Seventh Framework Programme (FP/2007-2013) / ERC Grant Agreement n. 321132, project TRAMAN21.Summarization: This paper proposes a freeway traffic controller with the objective of minimizing, at the same time, congestion phenomena and traffic emissions. A multi-class framework is considered in the paper, i.e two classes of vehicles (cars and trucks) are explicitly modelled and specific control actions for each vehicle class are computed. The controller is based on the formulation and solution of a constrained discretetime nonlinear optimal control problem for which a specific solution algorithm, the feasible direction algorithm, is used. The effectiveness of the proposed approach is shown and discussed in the paper by means of some simulation results.Παρουσιάστηκε στο: 14th Annual European Control Conferenc
