Dr. Danique Ton unraveling mode and route choice behaviour

Author: Dorine Duives

On the 17th of September Danique Ton has defended her thesis entitled ‘Unravelling mode and route choice behaviour of active mode users’ at the Delft University of Technology. Her thesis will soon be available and can be found in the repository of the TU Delft. We are happy to see that she passed this final hurdle with flying colours and wish the young new doctor all the best in her new position as a postdoc in our department.

In the morning, TRAIL organised a nice seminar to highlight this occasion, which was attended by more than 40 participants from TU Delft and other knowledge institutes in the Netherlands. Four experts in the field of travel behaviour modelling presented recent developments and applications. Prof. Patricia Mokhtarian presented a latent-class regression approach to determine the role of attitudes in perceptions of bicycle facilities. Prof. Elisabetta Cherchi studied latent constructs to model travel choice behaviour. Prof. Shlomo Bekhor discussed a new frequency-based transit assignment model which can consider online information and capacity restrictions. Prof. Bert van Wee closed the workshop with an introduction of a new concept in the field of policy-making for travel behaviour, namely that of ‘substitutability’.

USF Summer School meets Allegro

Author: Alphonse Vial and Giulia Reggiani


This August we organized two full days of active mode research for 18 Bachelors and Masters students from the University of South Florida. Together with Prof. Robert Bertini, the organizer of the trip, the students were visiting TU Delft and the Netherlands as part of a two-week summer school on sustainable transportation.


While the first day focused on Bicycle Queue Density and Discharge, the second-day program was built around Dutch Cycling Infrastructure and Perceptions. We had an excellent Allegro-lineup, and each of the two days included theory, experiments, data collection, data processing, analyses, discussions, and eventually barbecue & sports. Experiments and data collection were performed at the Green Village (a living lab for sustainable innovation on TU Delft campus), as well as on Delft’s cycle tracks.


The feedback we received from the students was excellent. We experienced them as being interested, energetic and always looking for interaction. They became active mode researchers for 2 days, by learning how to design their own experiments and data collection plans in order to answer research questions. In fact, they all collected their own data, processed and analyzed it and finally presented the results. The experiments and data analysis were not only for educational purposes, but the students actually were at the frontier of new science. In both their experiments as well as in their analyses, they contributed to the state-of-the-art research. But most of all, they had a GOOD TIME.


Thanks to Professor Rober Bertini for designing the summer school and for initiating the cooperation with the Allegro group. Recognitions, to the fantastic team that made it all happen: Giulia Reggiani, Lara Zomer and Alphonse Vial for the entire organization, and for leading the day on Physical and Perceived Networks. Victor Knoop, Marie-Jette Wierbos and Martijn Sparnaaij, thank you for contributing to the whole first day of research at the Green Village with insight on Densities of Active Mode Users. Finally, the students benefited from the guidance of Tim van Oijen during the data analysis and presentation session.
