When studying fluids it is frequently the case that the construction of a reasonable approximate theory becomes an elusive endeavor. The harder and interesting these problems are the better it is to have exact results, coming directly from the microscopic kinetics, both to test the existing theoretical approaches and to gain insights to new ones. To progress in the formulation of fluid dynamics...

Traffic microscopic traffic simulation models have become extensively used in both transportation operations and management analyses, which are very useful in reflecting the dynamic nature of transportation system in a stochastic manner. As far as the microscopic traffic flow simulation users are concerned, the one of the major concerns would be the appropriate calibration of the simulation mod...

Velocity-based models belong to the category of microscopic crowd simulation models. They recently appeared in the crowd simulation literature. They mathematically formulate microscopic interactions as a function of agents' states and their derivatives. In the case of collision avoidance, this property provides agents with the ability to produce anticipated smooth reactions, with great impact o...

This paper presents discussions on two critical aspects related to microscopic simulation; a methodology calibration/validation and the integration of path dynamics on large networks, which we consider the most significant two challenges in microscopic simulation for decision support and analysis in Advanced Traffic Management and Information Systems. On calibration/validation, we distinguish b...

Earthmoving operations are a major part of many construction projects. Because of the complexity and fast-changing environment of such operations, the planning and estimating are crucial on both planning and operational levels. This paper presents the framework ofa microscopic discrete-event simulation system for modeling earthmoving operations and conducting productivity estimations on an oper...
