Abstract
In this paper an attempt is made to study the suitability of different available cellular automata (CA) based models for mixed traffic. CA model structure is modified to incorporate typical mixed traffic characteristics. Different CA updating procedures have been used with the modified CA structure to know their suitability for modelling mixed traffic. Detailed parametric studies are carried out to understand the ramifications of modified CA structure. From the parametric studies carried out, Knospe’s brake light model (Knospe 2000) along with the modified CA structure, found to be useful in modelling mixed traffic. Using this new model, influence of slow vehicles such as trucks on the traffic stream is studied.
