Evaluation of car following (Car Following) simulation models

The use of traffic simulation software for performance analysis is developing rapidly. Therefore, it is important to know the models used in these softwares and the capabilities and limitations of the models used to ensure the accuracy of the results obtained. Among these models are car following models. So far, various models have been presented to express the behavior of vehicles in adjusting their distance to the vehicle ahead in the form of a mathematical formulation that is used in traffic simulation software. In this article, after reviewing the types of these models, the car models are compared in two traffic simulation software VISSIM and AIMSUN. For better analysis and display of the difference between the performance of these two softwares and analysis of their sensitivity.
