A car-following model considering the effect of electronic throttle opening angle over the curved road

This paper proposes an extended car-following model by taking the effect of electronic throttle dynamics into account on the curved road, in which the electronic throttle opening angle difference from multiple preceding vehicles at the previous moment is considered as a delay-feedback control signal. Then, the stability condition of the proposed model is gained using the control theory method. Considering the effects of friction coefficient, radius of curved road, and control signal, the numerical simulations are designed to study the change of traffic flow stability under different parameters. Results show that the radius and friction coefficient have a negative effect on stabilizing traffic flow, while the stability increases with an increase in the delay-feedback control coefficient. In addition, the numerical simulation also verifies that the control signal can reduce the fuel consumption of traffic flow. (C) 2019 Elsevier B.V. All rights reserved.
