Improved Generalized Force Model considering the Comfortable Driving Behavior

Abstract EN

This paper presents an improved generalized force model (IGFM) that considers the driver’s comfortable driving behavior.

Through theoretical analysis, we propose the calculation methods of comfortable driving distance and velocity.

Then the stability condition of the model is obtained by the linear stability analysis.

The problems of the unrealistic acceleration of the leading car existing in the previous models were solved.

Furthermore, the simulation results show that IGFM can predict correct delay time of car motion and kinematic wave speed at jam density, and it can exactly describe the driver’s behavior under an urgent case, where no collision occurs.

The dynamic properties of IGFM also indicate that stability has improved compared to the generalized force model.
