Caspar Chorus is professor of Choice behavior modeling at TU Delft, and head of the Transport & Logistics group at the Faculty of Technology, Policy & Management (Department Engineering Systems and Services). Caspar is member of the board of the International Association for Travel Behavior Research (IATBR), and editor-in-chief of the European Journal of Transport and Infrastructure Research (Platinum Open Access, listed in JCR). His research is supported by personal grants from NWO (Veni 2010 and Vidi 2012) and the ERC (Consolidator 2016). 


My main research and teaching aim is to increase the behavioral realism of choice models, by means of combining recent insights from the behavioral sciences and advances in econometric techniques. 

The domain of application for most of my work is Transportation, with a special interest in mobility modeling and transport policy analysis. However, I also develop and apply choice models in various other contexts, such as decisions made by consumers, patients, politicians, etc.

New discrete choice theory for understanding moral decision making behavior

In 2017, my team and I will start a five year long research effort which aims to develop and emirically validate new discrete choice theory for moral decision making. This research endeavour 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 patters. Sponsored by NWO (Netherlands Organisation 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.
