The real-time simulation of human crowds has many applications. Simulating how the people in a crowd move through an environment is active and ever-growing research topic. Most focuses on microscopic (or ‘agent-based’) crowd-simulation methods that model behavior each individual person, from which collective can then emerge. This state-of-the-art report analyzes advanced since year 2010. We foc...

The influence of agents heterogeneity on the microscopic characteristics of pedestrian flow is studied via an evacuation simulation tool based on the Floor-Field model. The heterogeneity is introduced in agents velocity, aggressiveness, and sensitivity to occupation. The simulation results are compared to data gathered during an original experiment. The comparison shows that the heterogeneity i...

The Cellular Automata method has been used to simulate the pattern formation of the Schlögl model as a bistable Reaction-Diffusion System. Both microscopic and macroscopic Cellular Automata approaches have been considered and two different methods for obtaining the probabilities in the microscopic approach have been mentioned. The results show the tendency of the system towards the more sta...

In this paper, we introduce GENOSIM: Genetic Optimizer for Traffic Micro-simulation Models. GENOSIM is developed as a pilot software, employing state of the art combinatorial parametric optimization to automate the tedious task of calibrating traffic microscopic simulation models. The employed global search technique, Genetic Algorithms, is integrated with a dynamic traffic microscopic simulati...

Macroscopic and equilibrium-based models for traffic assignment and simulation disregard many details of traffic movement. For some applications, one needs to understand and analyze microscopic properties. This paper discusses an agent-based simulation of route choice under different conditions of demand generation, number, and types of travelers. The effects of en-route decision-making and veh...

In this paper, we present a formal and operational framework for multiscale modeling and simulation. We focus on scale transfer viewed as the coupling between two models of the same system, one at the microscopic scale and the other at the macroscopic scale. We consider that some parameters of the macroscopic model are the result of microscopic processes described in the microscopic model. The ...
