📢 It is becoming our tradition to begin the New Year at TRB Annual Meeting. On 6th of January in Washington Zoltán and Grzegorz presented our poster titled Framework to Measure Properties of Microscopic Traffic Equilibria It shows what we called Routing ZOO (a sumo-based framework) thanks to which we want to check what Microscopic Traffic Assignment really is: what are its properties, stability, is it equilibrium etc. Draft repo, that soon we will use for bigger experiments, is here.

We started 2025 with good news - our open access publication with the TU Delft friends is already available in the Transportation Research Part A: Policy and Practice. In this paper using agent-based simulation modelling on the realistic case study of the city of Amsterdam, the Netherlands, we study the impacts of drivers’ ride acceptance behaviour, estimated from unique empirical data, on the ride-sourcing system where the platform applies regular and surge pricing strategies, and riders may revoke their requests and reject the received offers. Furthermore, we delve into the implications of various supply–demand intensities, a centralised fleet (i.e., mandatory acceptance on each ride request) versus a decentralised fleet (i.e., ride acceptance decision by each driver), ride acceptance rates, and surge pricing settings. An agent-based simulation, MaSSim is public and you can get it from this repo for more research like this.

Ten years after first train had become the distance between Krakow and Wieliczka Rafal had an honour to participate in the conference devoted to Fast Commuter Rail (Szybka Kolej Aglomeracyjna, SKA) and in debate not only about achievements over the years, but also about challenges, future plans, so as to make public transport more and more open and competitive.

At first view, the city’s transport system is a complex technical structure filled with machines 🚙 (vehicles) and engineering 🛣 (roads, tracks, bridges, etc.) - managed by engineers and algorithms. Nothing could be more wrong! Engineering only sets the boundary conditions here, but the main actors are us, people. Our decisions (what, when, which way and where I will go) determine the shape of this complex system. During 8th Silesian Science Festival KATOWICE Rafal will show it on a few examples, discuss two Nobel Prizes, including one in game theory, which we are currently playing among ourselves, but … soon will start playing with artificial intelligence 🤹‍♂️ Join us this Saturday, 7th December. Starting at 1:10 PM. Click here for more info about 8th Silesian Science Festival KATOWICE. Presentation

The latest publication with Arkadiusz Drabicki in collaboration with Oded Cats Has the COVID-19 pandemic affected travellers’ willingness to wait with real-time crowding information? is now available! 🚍 This study investigates the willingness to wait (WTW) to reduce (or avoid) overcrowding with real-time crowding information in urban public transport (bus and tram) journeys, analysing pre- vs. post-COVID travel behaviour attitudes.

🎤 Last week during Open Eyes Economy I spoke with Marek Tajchman about the future of AI and how crucial is to invest in Polish science. There is no innovation without basic research.
