Composite car following models

Abstract This paper addresses previous proposed car-following models and compares them with empirically collected data obtained through aerial photogrammetric techniques, and considers the possibility of using “composite” models to describe the real world situations. Four models are revisited, namely those associated with Chandler et al. (1958), Greenshields (1934), Greenberg (1958) and Edie (1961), and composite models were developed representing both congested and noncongested states. These results were more significant in data fitting and merit further consideration for use as descriptive flow-density models.
