A hybrid multi-scale approach for simulation of pedestrian dynamics

A. Kneidl, D. Hartmann, A. Borrmann
2013 Transportation Research Part C: Emerging Technologies  
The navigation field is updated dynamically during the runtime of the simulation, explicitly considering other pedestrians for determining the fastest path.  ...  improve the navigational behaviour.  ...  Thus, being interested in local small-scale behaviour of pedestrian flows, microscopic models are the approach of choice. They can be distinguished into force models (e.g.  ...

From Ant Trails to Pedestrian Dynamics

Andreas Schadschneider, Ansgar Kirchner, Katsuhiro Nishinari
2003 Applied Bionics and Biomechanics  
This paper presents a model for the simulation of pedestrian dynamics inspired by the behaviour of ants in ant trails. Ants communicate by producing a pheromone that can be smelled by other ants.  ...  In this model, pedestrians produce a virtual pheromone that influences the motion of others.  ...  Acknowledgements We thank D Chowdhury and H Klüpfel for helpful discussions and their collaboration on some of the results presented here.

Simulation of Pedestrian Movements Using Fine Grid Cellular Automata Model [article]

Siamak Sarmady, Fazilah Haron, Abdullah Zawawi Talib
2014 arXiv   pre-print
The model allows the use of different body sizes, shapes and speeds for pedestrian. The proposed model is used for simulating movements of pedestrians toward a target.  ...  The movements of pedestrians are smoother because of the finer grain discretization of movements and the simulation results match empirical speed-density graphs with good accuracy.  ...  Acknowledgements This research is supported by USM FRGS grant number 203/PKOMP/6711230 with the title "More Accurate Models for Movements of Pedestrians in Big Crowds".  ...

Modelling Unidirectional Crowd Motion in a Corridor with Statistical Characteristics of Pedestrian Movements

Tan Chen, Wei Wang, Yu Tu, Xuedong Hua
2020 Mathematical Problems in Engineering  
Lattice gas model is a kind of mature and convenient pedestrian simulation model.  ...  Based on an open pedestrian trajectory dataset, we first derived the relationship between local density and the distribution of pedestrian movements' length and then proposed an extended lattice gas model  ...  Next, we introduced the concept of local density, which can successfully describe the spatial occupancy of a small area around a pedestrian, and based on this we derived the relationship between local  ...

Sketching for Real-time Control of Crowd Simulations [article]

Luis Rene Montana Gonzalez, Steve Maddock
2017 Computer Graphics and Visual Computing  
However, controlling the behaviour of the pedestrians typically involves tuning of the system parameters through trial and error, a time-consuming process relying on knowledge of a potentially complex  ...  We demonstrate the effectiveness of the approach using a range of scenarios, producing interactive editing and frame rates for tens of thousands of pedestrians.  ...  The behaviour of the pedestrians may be determined by two forms of control: local and global. A combination of both controls is used in most crowd simulation systems.  ...

Towards a Dedicated Computer Vision Tool set for Crowd Simulation Models [article]

Sultan Daud Khan, Muhammad Saqib, Michael Blumenstein
2017 arXiv   pre-print
In this paper, we developed a computer vision tool set that can be helpful not only in initializing the crowd simulation models but can also validate the simulation results.  ...  The main features of proposed tool set are: (1) Crowd flow segmentation and crowd counting, (2) Identifying source/sink location for understanding crowd behavior, (3) Group detection and tracking in crowds  ...  Crowd simulation algorithms are purely based on mathematical models that can simulate the known behaviour of a person but could not simulate unpredictable behaviours.  ...

Humans do not Always Act Selfishly: Social Identity and Helping in Emergency Evacuation Simulation

Isabella von Sivers, Anne Templeton, Gerta Köster, John Drury, Andrew Philippides
2014 Transportation Research Procedia  
We demonstrate the impact of this new model on the behaviour of pedestrians and on evacuation times.  ...  However, most simulations of evacuation scenarios rely on outdated assumptions about the way people behave or only consider the locomotion of pedestrian movement.  ...  Acknowledgements This work was funded by the German Federal Ministry of Education and Research through the projects MEPKA on mathematical characteristics of pedestrian stream models (grant number 17PNT028  ...

Agent-based Large Scale Simulation of Pedestrians With Adaptive Realistic Navigation Vector Fields [article]

Twin Karmakham, Paul Richmond, Daniela M. Romano
2010 Computer Graphics and Visual Computing  
The techniques described for pedestrian simulation make use of parallel processing through graphics card hardware allowing simulation scales to far exceed those of serial frameworks for agent based modelling  ...  The results demonstrate that this is a robust and scalable method for implementing pedestrian navigation behaviour.  ...  Simulating groups of pedestrians is now almost exclusively performed by considering an individual approach, where agents interact directly to form emergent group behaviour, rather than using a top down  ...

Path Finding and Collision Avoidance in Crowd Simulation

Cherif Foudil, Djedi Noureddine, Cedric Sanza, Yves Duthen
2009 Journal of Computing and Information Technology  
We describe in this paper a system designed to simulate pedestrian behaviour in crowds in real time, concentrating particularly on collision avoidance.  ...  In order to deal with collision avoidance problems, priority rules are given to some entities as well as some social behaviour. These rules solved the problem of disorder in the crowd movement.  ...  Generally, the pedestrians form line segregation, each group takes a direction and the choice of the direction is taken from the sociological behaviours of the pedestrian.  ...
