CASPT2018 & related activities

Participated in CASPT2018, the flagship scientific conference on public transport systems which took place in Brisbane, Australia on 23-25 July.

Have had the following contributions together with colleagues:
– Frequency and Vehicle Capacity Determination using a Dynamic Transit Assignment Model
– Stopping Pattern and Frequency Determination for a Multi-Modal Network
– A Holding Control Strategy for Diverging Bus Lines
– Using Passenger Flows to Determine Key Interchange Connections for Public Transport Synchronization
– Assessing Disruption Management Strategies in Rail-bound Urban Public Transport from a Passenger Perspective
– Is Flat Fare Fair? Equity Impact of Fare Scheme Change
– Value of Reliability for the Waiting Stage, In-vehicle Stage and Transfer Stage of Demand Responsive Transport (DRT) Services
– Determinants of Passengers’ Metro Car Choice Revealed through Automated Data Sources: A Stockholm Metro Case Study
– Passenger Route Choice and Assignment Model for Combined Fixed and Flexible Public Transport Systems
– Can Passenger Flow be Explained by Network Topology in Public Transport?

In conjunction with this conference, we have organized an affinity workshop between the Smart Public Transport Lab delegation from TU Delft and KTH and the Public Transport Research Group in Monash, Melbourne, led by Prof. Graham Currie.

Finally, I teach in the European edition of the Planning Public Transport Services course in Melbourne, see info on: https://www.monash.edu/engineering/its/public-transport-short-course

The next conference will take place in Tel Aviv, Israel, where I will be the scientific chair of the TransitData stream.

PhD defense and TRAIL seminar

Congratulations Dr. Nadjla Ghaemi for successfully defending your PhD dissertation on “Short-turning Trains during Full Blockage in Railway Disruption Management” today!

The defense was followed by a TRAIL seminar where I gave a talk on “Robust passenger transport systems: Network, operations and user adaptations”

ITS Berkeley seminar

Monday, April 16, 2018 – , 1:00pm to 2:00pm, 212 O’Brien Hall

ITS Berkeley seminar announcement

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.

TRB 2018

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:

  1. The Potential of Demand Responsive Transport as a Complement to Public Transport: An Assessment Framework and an Empirical Evaluation. (Session 293, Monday 10:15 AM- 12:00 PM Convention Center, 147A) Alonso-Gonzalez M., Liu T., Cats O., van Oort N. and Hoogendoorn S.
  2. Individual, Travel and Bus Stop Characteristics Influencing Traverlers’ Safety Perceptions. (Session 556, Tuesday 10:15 AM- 12:00 PM Convention Center, 143B) Abenoza R.F., Ceccato V., Susilo Y. and Cats O.
  3. Constructing Spatiotemporal Load Profiles of Transit Vehicles with Multiple Data Sources. (Session 649, Tuesday 1:30 PM- 3:15 PM Convention Center, Hall E) Lou D., Bonnetain L., Cats O. and van Lint H.
  4. Strategic Planning and Prospects of Rail-bound Demand Responsive Transit. (Session 660, Tuesday 1:30 PM- 3:15 PM Convention Center, Hall E) Cats O. and Haverkamp J.
  5. Demand-anticipatory Flexible Public Transport Service. (Session 784, Tuesday 8:00 AM- 9:45 PM Convention Center, Hall E) van Engelen M., Cats O., Post H. and Aardal K.

In addition, will be presiding:

  • Poster session 650 on Transit Service Disruptions: Impacts and Mitigation Measures (Tuesday 1:30 PM- 3:15 PM, Convention Center, Hall E)
  • Poster session 651 on Economic and Optimization Models for Integrated Service Planning (Tuesday 1:30 PM- 3:15 PM, Convention Center, Hall E)

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.
