A global urban road network self-adaptive simplification workflow from traffic to spatial representation - Scientific Data
Urban road network is crucial for understanding and revealing the spatial logic of urban organization and evolution. However, existing urban road network datasets like OpenStreetMap are designed for traffic studies, treating each lane as a distinct spatial unit of mobility, which may not align with urban studies considering each road as an integration space for social and cultural dynamics. This study established a novel workflow to self-adaptively transform the global urban road network from t…

The popular meaning of "luddite" is a straw-man. It's a sloppy word with a sloppy meaning now, and it's one we'd do well to watch out for.
The actual reality of who the Luddites were is far more interesting, the center of the hard-fought struggles against owners of factories disrupting entire towns and cities economies with massively terrible results, centralizing power and money and leaving a great number of people without any control of their work, formerly artisans who'd had a hand in their own work, and many automated out of jobs. Luddites destroyed automated looms not because they hated technology. They destroyed automated looms because they were taking the livelihood they depended on, with no recourse, and it was a disaster for a good while, and then millwork has gone from those places probably forever.
The problem now with LLMs and automated research systems is there's very little way for workers and creators to stick their shoes in the machinery. They've tried (https://arxiv.org/abs/2407.12281) but mostly failed, since unlike a factory full of textile workers, the equipment is remote, the automation virtual, an intangible software object that few can access in any meaningful way.

We find that if superlinear scaling resources of cities -- such as economic and social activity -- are the primary drivers of city dwellers' utility, then cities tend to conv…

New simulations show how much colder European winters would get if AMOC collapses
A pair of meteorologists in the Netherlands has used new simulations to show just how cold many of Europe's cities could get if the Atlantic Meridional Overturning Circulation (AMOC) were to collapse due to global warming. In their study, published in the journal Geophysical Research Letters, René van Westen and Michiel Baatsen developed a climate model based on a range of ocean temperature changes that could arise due to global warming.

This is that list that got taken down. According to *Murphy v. NCAA*, the federal government cannot tell the states what laws they can write, and according to *United States v. California*, No. 18-16496 (9th Cir. 2019), the feds can't go after the states because of sanctuary cities and related immigration laws.

The Urban Model Platform: A Public Backbone for Modeling and Simulation in Urban Digital Twins
Urban digital twins are increasingly perceived as a way to pool the growing digital resources of cities for the purpose of a more sustainable and integrated urban planning. Models and simulations are central to this undertaking: They enable "what if?" scenarios, create insights and describe relationships between the vast data that is being collected. However, the process of integrating and subsequently using models in urban digital twins is an inherently complex undertaking. It raises questions…

Optimization under Attack: Resilience, Vulnerability, and the Path to Collapse
Optimization is instrumental for improving operations of large-scale socio-technical infrastructures of Smart Cities, for instance, energy and traffic systems. In particular, understanding the performance of multi-agent discrete-choice combinatorial optimization under distributed adversary attacks is a compelling and underexplored problem, since multi-agent systems exhibit a large number of remote control variables that can influence in an unprecedented way the cost-effectiveness of distributed…

Universal roughness and the dynamics of urban expansion
We present a new approach to quantity urban sprawl using tools from surface growth physics. Analyzing built-up area expansion in 19 cities (1985-2015), we uncover anisotropic growth with branch-like extensions and a piecewise linear relation between area and population. A universal local roughness exponent $α_{\text{loc}} \approx 0.54$ coexists with variable exponents $β$, $z$. As modeling urban sprawl remains an open problem, these results offer a necessary empirical basis for theory.

Process Mining on Distributed Data Sources
Major domains such as logistics, healthcare, and smart cities increasingly rely on sensor technologies and distributed infrastructures to monitor complex processes in real time. These developments are transforming the data landscape from discrete, structured records stored in centralized systems to continuous, fine-grained, and heterogeneous event streams collected across distributed environments. As a result, traditional process mining techniques, which assume centralized event logs from enter…

Disentangling Spatial and Structural Drivers of Housing Prices through Bayesian Networks: A Case Study of Madrid, Barcelona, and Valencia
Understanding how housing prices respond to spatial accessibility, structural attributes, and typological distinctions is central to contemporary urban research and policy. In cities marked by affordability stress and market segmentation, models that offer both predictive capability and interpretive clarity are increasingly needed. This study applies discrete Bayesian networks to model residential price formation across Madrid, Barcelona, and Valencia using over 180,000 geo-referenced housing l…

Modeling Urban Air Quality Using Taxis as Sensors
Monitoring urban air quality with high spatiotemporal resolution continues to pose significant challenges. We investigate the use of taxi fleets as mobile sensing platforms, analyzing over 100 million PM2.5 readings from more than 3,000 vehicles across six major U.S. cities during one year. Our findings show that taxis provide fine-grained, street-level air quality insights while ensuring city-wide coverage. We further explore urban air quality modeling using traffic congestion, built environme…

Transport Network, Graph, and Air Pollution
Air pollution can be studied in the urban structure regulated by transport networks. Transport networks can be studied as geometric and topological graph characteristics through designed models. Current studies do not offer a comprehensive view as limited models with insufficient features are examined. Our study finds geometric patterns of pollution-indicated transport networks through 0.3 million image interpretations of global cities. These are then described as part of 12 indices to investig…
