Because car following models are based on certain assumptions. Car following behaviour, in particular, has a significant impact on the accuracy of the simulation model in replicating traffic behaviour on the road. Researchers and practitioners commonly use carfollowing models for road traffic studies. Gipps model, one of the most extensively used carfollowing models, is calibrated against the same data and used as a reference benchmark. Carfollowing models have been developed to describe the dynamical characteristics of the moving vehicles. A great deal of investigation works were conducted in the last five decades to model the longitudinal interaction between adjacent vehicles as a result numerous models are available now. Applications, developments, and new features show all authors.
