Previous symposia were held in Leeds (UK, 2006), Leuven (Belgium, 2008), Takayama (Japan, in 2010), Martha’s Vineyard (USA, 2012), Salerno (Italy, 2014), Sydney (Australia, 2016), and Hong Kong (China, 2018). The 2020 Symposium (Seattle, WA, USA) was rescheduled to a virtual format in 2021 due to the COVID-19 pandemic. The 2023 DTA conference was held in Evanston (USA).

This Symposium series aims to foster excellence in dynamic traffic assignment (DTA) research and practice and provide a forum for exchanging innovative ideas and challenges on DTA and related transportation science problems. The theme of DTA2025 is “Beyond DTA”, recognizing the central role that DTA and network models have come to assume in many transportation planning and operations problems.  From strategic planning for emerging autonomous vehicle technologies and new shared mobility services, to the real-time operation of intelligent transportation and logistics systems, network models and DTA are called upon to provide the backbone analytics for modern transportation systems design and management. In this process, DTA-based methods increasingly interact with data streams from multiple sources, creating challenging new problem classes to address emerging opportunities for the delivery of mobility services.

The foundations are solid, and the field is wide open for innovations in fundamental theories, models, algorithms, and applications. DTA 2025 will provide a unique forum for researchers, academics, and practitioners for taking stock of the state of play and sharing insights and knowledge about novel problem classes and breakthroughs in various aspects of existing approaches.
