In Newell (2002), it is proposed that the car-following behavior is controlled by two factors, i.e., response time and distance offset. Each driver has two fixed factors in the following behavior. However, we find that there is internal heterogeneity of drivers, that is, the response time and distance offset cannot keep constant all the time, and show the characteristics of lognormal distribution. Thus, it is necessary to consider the heterogeneity within the driver into the model. This paper establishes a stochastic Newell’s model based on the probability density distributions of response time and distance offset from experimental data.

In this theoretical study, the lower hybrid wave disintegrates into two modes, under the condition that the, when the plasma electron oscillatory velocity is a few percent of the sound velocity: a shear Alfvén wave mode having low frequency and a lower hybrid sideband mode. On the present analysis, through the lower hybrid sideband mode and the lower hybrid pump wave, a ponderomotive force is applied that initiates the shear Alfvén wave mode. Now, the dust grains that are already present inside the plasma impact this instability. It is evident from the results that a rise in growth rate occurs with axial wave number, oscillatory velocity of pump waves, as well as with diverse amplitude of pump waves, relative density, etc., for typically existing complex dusty plasma parameters. However, the growth rated declines with the enhancement in applied magnetic field.
