This Symposium aims to foster excellence in dynamic traffic assignment (DTA) research and practice, and provide a forum for exchanging innovative ideas and challengs on DTA and related transportation science research problems. The theme of DTA2020 is “Modeling Multi-Modal Dynamic Transportation Network Systems in Smart Cities in the Era of Connectivity, Automation, and Sharing.” This is in response to the recent emergence and rapid development of new technologies and systems, such as connected and automated vehicles (CAVs), shared mobility, and smart cities, which provides great opportunities and grand challenges of DTA. They call for new theories, models, computational methods, and application scenarios to study multi-modal dynamic transportation networks with the emerging systems as essentially components and to apply the DTA methods in practical urban transportation networks.  

Practitioners and academics are cordially invited to share their knowledge, experience and insights on the design, analytics, investigations, analysis, planning, operation, engineering, co-ordination and management of smart transport systems, taking into account the time-varying characteristics of travel demand and supply and the interdisciplinary nature of the subject. The Symposium will last three full days (from Monday to Wednesday). The technical program may include plenary sessions, paper presentations, and interactive sessions.

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 Symposium in 2020 will be held in Seattle, WA from June 29 to July 1, 2020.
