The dynamics involved in this problem is described following a close analogy to compressible fluid dynamics. It is well known that vehicle clusters appear along a highway when the homogenous steady state taken as a reference is linearly unstable. The cluster properties are determined in an approximate way in terms of the parameters proper to each model and are compared between them. %K Traffic Flow %K Solitons %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=17699
