The graded potential of NH varies according to the intensity of signal from Sensory unit.
The frequency of signal is passed to the thalamus neuron NH, which takes it as its initial value for graded potential. As the intensity of received signal increases (depending on the decreasing distance between vehicles), the value of graded potential increases.
