Impressive submission pace
COeXISTENCE and SUM team members had a busy time but effects are visible to the naked eye. In the first month of the year we submitted 4 papers for hEART conference, 1 for EWGT conference, 1 for CASPT conference and 1 for ICML conference. Big applause for dedication and work👏 Fingers crossed for positive news!

Soon in Brussels
📣IGLO Open on the Polish Presidency: Programme and R&I Priorities is only one week away! Don’t wait and register via this LINK. This event will serve as a platform to present and discuss Poland’s strategic vision and priorities in Research and Innovation during its presidency. Among many great scientists there will be also Rafal. He will take part in panel discussion with ERC laureates moderated by Prof. Leszek Kaczmarek, ERC Scientific Council Member. Add to your calendar: Wednesday, January 22, 2025 10:00-13:00 CET

MoMaS is the answer! 💡
Have you ever wondered how do two-sided platforms like Uber grow? Purely microscopic phenomena lead to complex patterns of market share evolution. Now, with our MoMaS you can simulate and understand why Uber prevailed, and its competitors (Bolt) enter the market with easy. 👏 Congratulations to Farnoud and Rafal on their outstanding results published in Transportation Research Part C: Emerging Technologies!

When science meets social needs 🤝
With the local authorities and recognised researchers during the conference Czuję pociąg do Myślenic in Myślenice Rafal discussed about the planned railway line from Myślenice to Kraków and its impact on the local society and its potential to be a corridor for the sustainable development of housing estates.

COeXISTENCE team hit the ground running by participating in TRB2025
📢 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.

The New Year has brought some good news
💣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.

10 years of Fast Commuter Rail 🚆
10 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.

8th Silesian Science Festival KATOWICE is coming 🚀
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

Our latest paper published in Travel Behaviour and Society💣
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.

Some thoughts on Polish science
🎤 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.

Join us at ML in PL 2024
Let us take you on an extraordinary journey during which we show how autonomous vehicles can disturb our cities by applying reinforcenment learning in their route choice. 🎤 This Sunday Nov 10 at 2:30 PM Anastasia and Onur are taking up the reins and waiting for you in Copernicus Science Centre. So don’t wait and register for our tutorial. Reach out for more info

Our 'envoys' are already in Toulouse
🚗🚗🚗 We are proud to share our achievements in urban traffic dynamics at 17th European Workshop on Reinforcement Learning. Meet Onur and Anastasia who are proving that RL-enabled autonomous vehicles can optimize behavioral objectives by learning to choose better routes! Just take a look how we came to this conclusion 👈
