Abstract
In this paper, a car following model is built on observations and analysis of human driver behaviour. This model considers both the gap distance and the speed difference between two vehicles, and determines when and how a driver accelerates (decelerates). The simulation result shows that the probability distributions for both speed differences and time headways match the data from observation. In addition, some theoretical analysis are given to verify this model. The distribution of time headways is consistent with the empirical conclusion; and a stochastic differential equation summarized from the model represents the interdependence of gap distance and speed difference. The model is simple to understand and is an improvement on former work.
