Researchers at TUD and Fraunhofer SCAI illustrate why energy and mobility systems can only be understood as a whole

Why do well-intentioned measures in power grids or transportation systems sometimes fail to produce the desired outcomes, or even make the situation worse? A new study by researchers at TU Dresden and Fraunhofer SCAI reveals that sustainable infrastructures often behave differently than one might intuitively expect.

A review article published on April 23, 2026, in Nature Computational Science clearly demonstrates: The key characteristics of energy and mobility systems only become apparent when viewed as complex, dynamic systems as a whole.

Prof. Marc Timme (TUD) and Mehrnaz Anvari (Fraunhofer SCAI) compiled the latest findings on the dynamics of interconnected infrastructures. The focus is on how power grids and transportation systems react to changes and why even tiny and seemingly insignificant changes often have larger and unexpected consequences.

Scientists at the Center for Advancing Electronics Dresden (cfaed) demonstrate in a new study how systems can shift from disorder to near-perfect order with unprecedented abruptness. The research team of TUD Dresden University of Technology reveals with this study, published in Nature Communications, a novel class of transitions in coupled oscillatory units, termed "extreme synchronization transitions”, challenging our traditional understanding of phase transitions.

Phase transitions are fundamental phenomena emerging across natural and human-made systems – from ice melting and traffic jam formation to the magnetization of metals. They mark qualitative changes in the degree of ordering of system constituents. Understanding how and why these transitions emerge constitutes one of the cornerstones of research on complex systems in nature and engineering.

Prof. Marc Timme, head of the Chair of Network Dynamics, won the prestigious Reinhart Koselleck grant promoted by the Deutsche Forschungsgemeinschaft (DFG) – an outstanding success!

The Reinhart-Koselleck grant funds research on strongly driven nonlinear network dynamics for 5 years and amounts to 1.5 Million Euros (incl. overhead). It constitutes the largest single-applicant research grant by the DFG, roughly comparable to an ERC grant on the European level.

Public transport systems vary widely around the world. Developed countries in the Global North usually have centrally-planned public transport systems with fixed routes and timetables. In contrast, in the developing countries of the Global South, making up more than 80 % of the world's population, public transportation is mostly provided by informal transport services featuring ad hoc routes, e.g. in the form of privately organized minibus services. Due to their seemingly chaotic operation, such informal transport services are often considered as inefficient from an outside perspective. Due to a lack of data a systematic comparison was not possible so far.

In a new scientific paper recently published in Nature Communications, Kush Mohan Mittal, Marc Timme and Malte Schröder from the Chair of Network Dynamics at TU Dresden analyze and compare the structural efficiency of more than 7,000 formal and informal bus lines across 36 cities and 22 countries. One of the central, surprising findings is that the routes of informal transport self-organize in a way that reaches or even exceeds the efficiency level of centralized services.

Invitation to the kick-off event on July 19 (online)

Where is shared mobility particularly useful and how can we ensure it is sustainable? A new research project has been running at the Chair of Network Dynamics at TU Dresden since July 1, 2023. Ridepooling models developed at the chair are now to be applied nationwide. The researchers are developing a "potential map" of different regions in order to obtain an overview of the applicability of this new type of transport service. The "Where2Share" project is funded by the German Federal Ministry for Digital and Transport as part of the mFUND innovation initiative over the period July 2023 to December 2024 with a total of almost 193,000 euros.

Once a year, BASF Schwarzheide GmbH selects outstanding scientific works from TU Dresden focusing on sustainability, circular economy or digitalization. One out of three prizes in 2022, endowed with 1,500 Euros, was awarded to David-Maximilian Storch from our chair. His dissertation entitled "Statistical Physics of Urban Mobility" sheds new light on the complex dynamics of modern digital and shared mobility services. The work in particular uncovered how adoption of ride-sharing may be promoted, thus improving more sustainable transport through cleverly using digitization.

visualisation of route choice schemes of cyclists in urban areas
The route choice of cyclists is subject to various decision factors. For example, many prefer a separate bike lane (top left) instead of sharing space with dense car traffic (top right). Depending on whether streets with heavy car traffic (thick edges) are equipped with dedicated bike paths (blue) or not (gray), cyclists take the direct route (black arrow, bottom left), take detours to stay on bike paths (bottom center) or ride on small side streets (thin edges) (bottom right). Image author: Christoph Steinacker

Turning it downside up: Novel, network-dynamic planning approach for urban bike path infrastructure enables demand-driven design of cycling networks by reversing the usual approach. The new concept could improve the bike-friendliness of cities - and thus their sustainability and climate footprint.
In surveys, a large majority of respondents usually agree that cycling can make a significant contribution to reducing greenhouse gases and to sustainable transport, especially in densely populated areas. In contrast, for many countries in reality there is a large gap between desired and actual numbers. In Germany, for example, only 20% of the short-distance of everyday trips in residential environments are covered by bicycle.

Last Friday, the extremely popular Long Night of Science (Lange Nacht der Wissenschaften) finally took place again in Dresden, when countless research institutions open their laboratories and let the young and old participate in the diversity of their research topics. The central closing event of the #LNdWDD (with 32.000 visitors!) was a big Science Slam in the almost full Audimax of the TU Dresden. The 6 participants, 5 of them scientists on early career stages and one professor, who did not take part in the competition, are doing research in different fields such as chemistry, biology, physics or traffic science.

The participant from cfaed, Charlotte Lotze (Chair of Network Dynamics), bridges the last two topics: Based on physics, Charlotte is investigating a traffic-related topic in her PhD thesis.
