About
About the IACD
The International Association for Collective Dynamics (IACD) is a non-profit scientific association. It was founded on 18 June 2026 during the steering committee meeting at the TGF26 conference in Bristol. It is currently being established as a German non-profit association (Verein in Gründung, i. G.); registration as an eingetragener Verein (e.V.) is in progress, with its seat in Düren.
The association gives the international community studying collective dynamics — pedestrian and evacuation dynamics, crowd science, traffic and granular flow, and related fields — a lasting organisational and legal home, and supports the continuity and quality of the conferences it grew from, in particular:
- PED — Pedestrian and Evacuation Dynamics
- TGF — Traffic and Granular Flow
Purpose
In accordance with its statutes (§2), the IACD promotes science and research and civic and professional education, including support for students and early-career researchers, in the field of collective dynamics. It does so in particular through organising and supporting scientific conferences, promoting international cooperation and good scientific practice, publishing scientific results, and backing young researchers.
The association acts selflessly and pursues exclusively non-profit purposes.
