Contexte et atouts du poste

Large-scale events
- music festivals, sporting ceremonies, urban celebrations
- are organised with increasing frequency and scale, and their planning routinely raises complex crowd management questions regarding layout, capacity and safety. Crowd simulation is one of the few tools currently available to support this planning stage, allowing organisers to anticipate crowd flows or evaluate evacuation procedures. However, it remains fundamentally limited to a global, external, desk-based perspective: a simulation is configured with parameters set at the scale of an entire site
- density, flow directions, entry and exit points
- run as a whole, and observed from the outside, typically through 2D visualisations or bird's-eye 3D renderings. This paradigm is well suited to large-scale planning, but it cannot capture how a crowd interacts with the specific physical layout of a venue, how attendees experience being immersed within it, or how staff should be trained to navigate and make decisions in complex, situated crowd configurations.

This PhD position is part of PEAR, a collaborative ANR PRCI project between Inria, the Luxembourg Institute of Science and Technology (LIST) and the firefighter department of the Laboratoire Central de la Préfecture de Police de Paris (LCPP), with Hellfest Productions and Paléo Arts & Spectacles as festival partners. PEAR is driven by the hypothesis that combining realistic virtual crowd simulation with immersive eXtended Reality (XR) can fundamentally change how large-scale events are planned, by shifting the perspective from a global, external view of crowds to an embodied, first-person, on-site experience of crowd dynamics. Rather than configuring a simulation from a desk and observing its output from outside, users would be physically present within a virtually populated version of a real environment, through Augmented Reality (AR), and explore crowd scenarios locally and interactively, directly on-site.

The prototypes developed within PEAR will be confronted with concrete, real-world use-cases. The primary evaluation ground is the New Year's Eve celebration on the Champs-Élysées, led by the LCPP, which brings together over one million people in a dense urban environment each year and requires revising layout configurations, barrier placement and field team deployment for every edition. Findings will subsequently be generalised to the Hellfest and Paléo festival sites, to validate the applicability of the approaches developed in this position across different event formats, scales and physical configurations.

Mission confiée

Within PEAR, this PhD focuses specifically on how crowd scenarios can be simulated, authored and configured locally and interactively, directly on-site through AR
- as opposed to being configured globally from a desk. It is structured around three complementary objectives.<
