A model for car following based solely on optical parameters was developed and compared with performance of human drivers in a simulator. The model uses the optical size of the back of the car being followed and the first derivative of its optical size as inputs. The model consists of two components: one that accelerates to maintain the visual size of the leading car, and another that accelerates to minimize changes in the rate of change of the visual size of the leading car. The simulator presented drivers with a leading car that was changing its velocity according to a sum of non-harmonic sines. Comparisons of human drivers’ performance with the models’ show a high degree of similarity
