The first part of the video visually explains the various technical parts discussed in the paper.
The second part consists in two examples:
- Stonehenge-like environment: the environment demonstrates that it is crucial to have a variety of solutions to a navigation query in order to avoid congestion points and completely pedestrian-free areas. In this example, there are 1000 pedestrians navigating between two points, identical for all (1 query only). The video shows that the computed solution covers the whole environment. The accelerated part of the video shows the temporal evolution of the dispatch. 
- City environment: the environment is large and the number of pedestrians is high. The flow movement planification is done in a few mouse clicks and in a very short time. The simulation is in real time due to the LOS (level of simulation) principle.
