Effects of electronic throttle dynamics in non-equilibrium heterogeneous traffic flow without lane discipline

Abstract

Urban transportation systems are quickly developing more intelligent and networked systems. To further enhance the intelligent networked traffic environment, this study undertakes a thorough investigation and analysis of the features of heterogeneous traffic flow in a linked environment without lane discipline. A new non-equilibrium mixed traffic flow macroscopic model is proposed in connection with electronic throttle dynamics in light of the significance of electronic throttle angle information for vehicle-to-vehicle communication technologies. This paper investigates the stability of mixed traffic systems using a small disturbance method, as well as the nonlinearity of the systems is analyzed near the neutral stability curve. The effects of electronic throttle opening angle, lateral gap, and CAV penetration rate on the evolution of the traffic flow density wave are numerically investigated. The numerical experiment also compares and evaluates how the new model and three other scene models fares in terms of tiny perturbation evolution, energy consumption, and extra emission. The experiment's finding demonstrated that this macro model had a larger stable domain and less energy consumption and extra emissions when compared to other scenarios.
