Abstract
With the advances in the computational technology, microscopic traffic simulation models have become more realistic than ever, for example, 3D animations. They have been widely adopted as decision-supporting tools on various traffic operation and management studies. However, very few studies analyzed pros and cons of these models. At times, a microscopic simulation program is selected only because it was available for the engineers at the time of study. In practice, model selection has not been well exercised mainly due to the lack of available literature and experience. This paper presents a quick overview of four microscopic traffic simulation models and evaluates their performances using a case study of modeling a coordinated signal system. Models studied in this paper are CORSIM, Paramics, SIMTRAFFIC, and VISSIM. In order to provide reference performance measures for various traffic signal settings including pretimed and actuated controls, SYNCHRO program is utilized.
