Abstract
This study proposes a new car-following model considering the effects of the electronic throttle dynamics to capture the characteristics of connected autonomous vehicular traffic flow without lane discipline. In particular, the proposed model incorporates the effects of both electronic throttle opening angle and lateral gap into the traffic flow model by assuming that the information on electronic throttle dynamics is shared by surrounding vehicles through vehicle-to-vehicle communications. Stability of the proposed model is analyzed using the perturbation method. Numerical experiments analyze three scenarios: start, stop and evolution processes for the scenarios of lane-discipline-based full velocity difference (FVD) model, non-lane-based full velocity difference car-following (NLBCF) model and non-lane-discipline and throttle-based car-following model, respectively. Results from numerical experiments illustrate that the proposed car-following model has a larger stale region compared with the FVD and NLBCF models. In addition, it also demonstrates that the proposed car-following model can better represent the characteristics of connected and autonomous vehicular traffic flow in terms of the responsiveness, smoothness and stability with respect to the position, velocity, acceleration/deceleration and space headway profiles.
