An extended FVD model considering road radians and gradients

The microscopic car following model can depict the interaction between adjacent vehicles, but the existing studies rarely consider the effect of complex road conditions on the model. Based on the FVD model, an extended car following model with the consideration of the road radians and gradients is proposed in this paper. The linear stability condition is obtained by applying the linear stability theory. Experiments in different scenarios are carried out by VISSIM to evaluate the model performance. Results show that the extended FVD model can accurately reflect the driving behavior under real road conditions.
