This paper presents an Anisotropic Mesoscopic Traffic Simulation (AMTS) model that was used to support large-scale network traffic dynamic modeling. The proposed AMTS model is a vehicle-based mesoscopic traffic simulation model that explicitly considers anisotropic property of traffic flows into vehicle trajectory update during simulation. Discussions presented in this paper focus on the modeling concept and techniques of applying the proposed AMTS model to uninterrupted and interrupted flow conditions. As of this study, sufficient conditions for maintaining the first-in-first-out (FIFO) during simulation are presented; further, basic traffic flow properties such as shockwaves and macroscopic characteristics of the simulated traffic flow are also presented and discussed. The advantage of the proposed ATMS model lies in improved representations of traffic dynamics without significantly increasing the computational requirement.
