A car-following model accounting for the driver's attribution

In this paper, we use the FVD (full velocity difference) model to develop a car-following model with consideration of the driver's attribution. The numerical results show that the proposed model can qualitatively reproduce the effects of the driver's attribution on each vehicle's speed, acceleration, fuel consumption and exhaust emissions under two typical traffic states, i.e., the aggressive driver enhances his speed, acceleration, fuel consumption and exhaust emissions while the conservative driver reduces his speed, acceleration, fuel consumption and exhaust emissions, so the aggressive driver's speed, acceleration, fuel consumption and exhaust emissions are greater than those of the neutral driver and the neutral driver's speed, acceleration, fuel consumption and exhaust emissions are greater than those of the conservative driver. In addition, we further study each vehicle's speed, acceleration, fuel consumption and exhaust emissions when aggressive drivers, neutral drivers and conservative drivers are uniformly mixed. The numerical results show that there are no prominent differences between the mixed traffic flow and the homogeneous traffic flow consisting of neutral driver, i.e., each vehicle's speed, acceleration, fuel consumption and exhaust emissions are similar to those of the neutral driver.
