About the research centre or Inria department
Inria, the French national research institute for the digital sciences, promotes scientific excellence and technology transfer to maximise its impact.
It employs 2,400 people. Its 200 agile project teams, generally with academic partners, involve more than 3,000 scientists in meeting the challenges of computer science and mathematics, often at the interface of other disciplines.
Inria works with many companies and has assisted in the creation of over 160 startups.
It strives to meet the challenges of the digital transformation of science, society and the economy.
This postdoc position aims to participate in the development of new technologies to assist in the operational management of crowds during mass events using computers. During large gatherings, the density of people can become very high, creating a risk of turbulent crowd movements, shock wave propagation or trampling, and consequently, leading to vicitms by crushing or suffocation. The analysis and understanding of these phenomena is crucial to eventually enable better crowd management, and to provide technological solutions to assist public place managers in their operational management.
More specifically, this position aims to develop methods for analysing the global movement (macroscopic analysis) of the crowd filmed on video. The objective is to create a processing chain that includes video capture of crowd scenes, estimation of apparent movement in the image, calculation of the characteristics of this movement, extraction of relevant information for feedback and possible alerting of those responsible for the operational management of the site.
This position is available for a team of about ten people specialized in crowd analysis, modeling and simulation. This work is also carried out in close collaboration with industrial partners in the field of crowd simulation for the design and management of public places. Finally, this work includes an important experimental part. We aimed to implement the technologies developed during events such as music festivals or in high-traffic areas.
In this position:
- You are in charge of developing macroscopic methods for analyzing crowd movement, based mainly on a modal analysis of apparent movement . A direction envisaged and to extend this analysis in space-time space (limited to space to date).
- You are in charge of a scientific watch on the field of operational crowd management, on methods of measuring and analyzing crowd activity, and on crowd management assistance technologies.
- You are in charge of planning and carrying out the experiments necessary for the evaluation and empirical validation of the methods developed, in close collaboration with public place managers and mass event managers.

In this position
- You coordinate the IT development of solutions that implement crowd motion analysis. You maintain an operational version of the video processing chain. You coordinate field experiments.
- You disseminate your results to the scientific community (publications, journals and scientific conferences). You are also involved in a scientific popularization effort aimed at the general public. You participate in making your technological results available to the public.
- You work with local team members to integrate the analytical methods developed as part of the broader crowd modeling and simulation process. You will explore relevant internal collaborations.
- You collaborate with our industrial partners to consider the industrial transfer of your solutions.
- You participate in the supervision of students who share the same objective of crowd movement analysis.
