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.

- Investigating Potential Transit Ridership by Fusing Smartcard and Global System for Mobile Communications Data (Session 491, Monday 6:00 PM- 7:30 PM, Convention Center, 147A)
- Willingness to Pay for Safety Improvements in Passenger Air Travel (Session 678, Tuesday 1:30 PM- 3:15 PM , Convention Center, Hall E)
- How Do People Cycle in Amsterdam? Estimating Cyclists’ Route Choice determinants Using GPS Data from an Urban Area (Session 878, Wednesday 2:30 PM- 4:00 PM , Convention Center, 102B)
In addition, will take part in:
- Poster session 250 on New Tools to Inform Transit Management and Decisions (Monday 8:00 AM- 9:45 AM, Convention Center, Hall E) which I will be presiding
- Lecture session 748 on Ensuring Public Transport Networks are Connected: For Everyone, at All Times (Tuesday 3:45 PM- 5:30 PM, Convention Center, 144A) on which I will be the discussant
In conjunction with the TRB conference I will also participate and present in the following events:
- Winter General Meeting of the PTV Scientific Advisory Board on which I will present past and on-going research on transit assignment models, Jan 10
- Shared Mobility from a Public Transport Perspective at the workshop on Shared Mobility at the Netherlands Embassy in Washington, Jan 12
- Towards Passenger Experience of Service Reliability: Field Implementation and Smartcard Analysis, invited talk at Washington Metropolitan Area Transit Authority, Jan 13
Looking forward to meeting many colleagues on one of these events or elsewhere in what will surely be an intriguing week!
INSTR2015 – 6th International Symposium on Transportation Network Reliability – the Value of Reliability, Robustness and Resilience, took place yesterday and today in Nara, Japan. First time that I take part in what seems to be a very relevant conference for my line of research concerning the reliability and vulnerability of public transport systems.
Here you can find my conference contributions concerning:
(1) Multi-crtieria evaluation of the resilience value of public transport investment plans based on a full-scan approach with the Stockholm public transport development plan as a case study (click for paper: instr2015_Cats_resilience_value)
(2) Investigating the role of exposure in public transport network vulnerability. A work that was preformed together with Menno Yap and Niels van Oort based on estimating large disruption data from the Netherlands and analyzing the impacts of accounting for exposure on the identification and evaluation of link criticality. (click for paper: instr2015_EXPOSURE). Below: Menno presenting on INSTR.
(3) Analyzing the impact of partial (unlike complete) failures. Together with Erik Jenelius, we studied the relation between the extent of capacity reduction at the line level and its consequences on societal costs by performing a full network scan for the Stockholm network (click for paper: Beyond a complete failure INSTR) Below: Erik presenting on INSTR.
Each of these studies deployed a distinctly different methodologies – network topology analysis (while accounting for travel impedance and demand), static assignment model and a dynamic agent-based transit assignment model, respectively.
Below: Still astonished by the Japanese public transport system!
On Thursday, November 20, I had the privilage to present highlights from my research to MIT transit group led by Prof. Nigel Wilson and thereafter had the opportunity to disucss ongoing research activities with group members.
The seminar was entitled: “Unraveling and modeling the dynamics of public transport systems: Theory and applications”, where I briefly presented the transit operations and assignment model, BusMezzo, and its applications to service reliability and control, congestion and evaluation of increased capacity as well as service disruptions and the value of real-time information provision.
