Seminar abstract: The metropolitan passenger transport landscape is shifting due to a combination of technological and social developments which enable both service providers and service users to become increasingly adaptive. Service providers can manage their resources to better cater for prevailing demand patterns, while service users can adjust their behaviour in response to real-time information. In this seminar, I will present our work on modelling system dynamics and the interaction between supply and demand under uncertainty in relation to tactical planning (e.g. fleet size and composition, frequency setting) and real-time management (e.g. trip dispatcher, disruption management) of fixed line-based as well as flexible on-demand services.
Looking forward to meeting many colleagues and friends at the Transportation Research Board (TRB) 97th Annual Meeting in Washington DC next week (January 7-11)!
The following studies which I have been involved in together with students and colleagues will be presented at TRB this year:

In conjunction with the TRB conference, Jaime Soza Parra and I meet with Washington Metropolitan Area Transit Authority on Jan 11 to present and discuss the preliminary results of our evaluation of their headway-control experiment.
I participate in the hEART conference which take place this week in the Technion – Israel Institute of Technology, Haifa.
After hosting it last year in Delft, it is great to attend it in the campus where I have studied for four years and excited to share the experience gained in the following studies:
- “Coordinating Merging Public Transport Operations Using Holding Control Strategies” presented by Georgios Laskaris
- “Tactical Service Design and Vehicle Allocation Optimization“, which I present
- “An Integrated Trip Assignment Model for Passenger Rail Systems” presented by Flurin Hänseler
- “Traveler’s Perceived Safety at Bus Stops in Stockholm, Sweden”, presented by Roberto Fernandez Abenoza
Will be attending MT-ITS 2017, the 5th IEEE International Conference on Models and Technologies for Intelligent Transportation Systems, together with colleagues with whom I collaborated on public transport -related studies.
I am involved in the following contributions that will be presented in the upcoming conference:
- Analysis of Network-wide Transit Passenger Flows based on Principal Component Analysis. (Presenter: Ding Luo)
- Simulating the Effects of Real-time Crowding Information in Public Transport Networks (Presenter: Arek Drabicki)
- Impact of Relocation Strategies for a Fleet of Shared Automated Vehicles on Service Efficiency, Effectiveness and Externalities (Presenter: Konstanze Winter)
- Real-time Short-turning in High Frequency Bus Services based on Passenger Cost (Presenter: David Leffler)
- Measuring Spill-over Effects of Disruptions in Public Transport Networks (I will present work performed with Sanmay Shelat)
Looking forward to my first MT-ITS experience!
Added on 16-8-2017: links to all conference papers are available on the Publications page.
Will be attending the Transportation Research Board (TRB) 96th Annual Meeting in Washington DC next week and will also take part in several events that organized in conjunction with TRB.
