CTS at the DTA Sympostium, Martha's Vineyard, Massachusetts, USA

Martha’s Vineyard, Massachusetts, USA

On 5 June, Dr. Jing Bie gave a presentation on day-to-day traffic dynamics at the 4th International Symposium on Dynamic Traffic Assignment (DTA), held on Martha’s Vineyard, Massachusetts, USA. The talk is based on his recent paper Extending Prospect Theory for Modeling Day-to-day Traffic Dynamics: risk aversion and equilibrium stability, co-authored with CTS staff Jaap Vreeswijk and Prof. Eric van Berkum. This paper investigate the over-day route choice behaviour of travellers. It shows that risk aversion contributes to network stability. Moreover, insensitivity of travellers (“indifference band”)  implies that changes applied to the network have to pass certain thresholds in order to cause any behavioural reactions.

The biennial DTA symposium attracts about 100 scholars and practitioners from around the world. Past events have taken place in Leeds (2006), Leuven (2008), and Takayama, Japan (2010). A unique feature of the DTA symposia is that all sessions are plenary. Programme of the 2012 event can be found at the symposium website: The next DTA symposium will take place in Salerno in summer 2014.
