C.G. (Caspar) Chorus


As a professor of Choice behavior modeling, together with a team of fellow researchers at TU Delft and scholars from outside our university, I develop and empirically test quantitative, formal models of human decision making. Crucially, we attempt to improve the behavioral realism of such choice behavior models, without compromising on mathematical tractability. This endeavour is supported by funding from personal grant competitions at the national and European level (NWO Veni 2010 and Vidi 2012; ERC Consolidator 2016). See my FULL CV (pdf, January 2018) for a full listing of my teaching and research activities, PhD-students and postdocs, editorial positions and professional memberships.


My main research and teaching ambition is to understand – through modeling, experimentation, empirical analysis and simulation – the rationality, sociality and morality of human choice behavior. This is a multi-disciplinary endeavor, encompassing fields such as econometrics (discrete choice theory), psychology, sociology, empirical ethics, and social simulation.

In line with my being head of the Transport & Logistics section at the Faculty of TPM, the domain of application for much of my work is Transportation, with a special interest in modeling and predicting traveler behavior in the context of new transport technologies such as automated driving, electric vehicles, and mobility-as-a-service. However, I also study choice behavior in various other contexts, such as Environment & Energy, Health, Political Sciences, Marketing, etc.

New discrete choice theory for understanding moral decision making behavior
In 2017, my team and I have started a five year long research effort which aims to develop and empirically validate new mathematical (discrete choice and agent based) models for moral decision making. This research endeavor is funded by a 2 million euro ERC Consolidator grant.

Spatial and Transport Impacts of Automated Driving
Studies the long term impacts of automated driving, on mobility and land use patterns. Sponsored by NWO (Netherlands Organization for Scientific Research) – SURF program.

Towards a regret based paradigm for the ex ante evaluation of transport policies
Studies the integration of random regret minimisation models of decision making, for economic appraisal and large scale travel demand forecasts. Sponsored by NWO (Netherlands Organisation for Scientific Research) – VIDI program.

Traffic information as a tool to bridge the gap between User Optimum and System Optimum
Studies how providing targetted travel information to boundedly rational and non-selfish travelers can lead to more efficient traffic flows. Sponsored by NWO (Netherlands Organisation for Scientific Research) – TRAIL program.
