Monitoring air quality is essential for a healthy living environment and can be achieved through various sensor types. While high-cost stationary reference sensors provide precise data, their limited deployment reduces overall coverage. Low-cost mobile sensors (LCSs) can complement stationary sensors,… Read More »Joint Optimization of Bus-Based Mobile Sensing and Reference Sensor Deployment for Urban Air Quality Monitoring

Accurate crowd statistics are essential for urban safety, smart city services, and event management, but also risk exposing sensitive information. Precise counts can enable adversaries to identify individuals by correlating released statistics with external data. We propose a novel protocol… Read More »Differentially Private Crowd Monitoring over Encrypted Bloom Filters

Urban mobility systems face growing challenges. While various smart mobility solutions have been proposed, there is still a lack of comprehensive tools for assessing the impact of these solutions in a dynamic and iterative manner. Recent literature increasingly adopts the… Read More »Digital twin federation for urban mobility assessment: Definition, pillars, and a human-in-the-loop functional architecture

Cars remain the most widely used mode of transport today. However, in many urban areas, high car usage leads to negative externalities such as congestion, pollution, and inefficient land use. Optimising parking policies in cities is a promising approach to… Read More »Multi-objective optimisation of parking capacities in urban areas

Application fingerprinting is essential for network management and security, enabling accurate traffic classification and the enforcement of Quality of Service (QoS) policies. In this work, we propose a scalable method for mobile application fingerprinting that leverages MinHash and Locality-Sensitive Hashing… Read More »Scalable, Semi supervised Mobile App Fingerprinting using LSH

The importance of the bicycle in shaping urban sustainable mobility systems is often overlooked. In orderto create healthier, cleaner, and more livable cities, a shift away from car dominance is needed, andsubsequently, the bicycle should get a more prominent role… Read More »Cycling performance in Dutch cities and the role of local cycling policies A multilevel modelling approach

As car use in cities continues to grow, causing issues such as congestion, air pollution, and the inefficient use of public space, Municipalities across the Netherlands are working to address this by promoting alternatives like shared mobility. For this purpose,… Read More »Understanding Transport Mode Choice for Business-Related Trips Among SME Employees 

Cars and roads have helped create modern society. However, their use comes at a cost for cities and their residents, in particular with respect to liveability. To improve liveability, cities are implementing a wide range of measures. This paper addresses… Read More »A framework of success factors and barriers for urban car reduction in European cities 

The growing population of the Netherlands is putting pressure on the accessibility and liveability of Dutch cities. To address both challenges new mobility policies prioritise quiet, low-emission and space-efficient modes of transport. This changing perspective on urban mobility is thus… Read More »The influence of parking on car ownership

Cars remain the dominant mode of transport, as they increase accessibility, offer status and comfort. However, the increasing use of private cars also causes issues such as congestion, emissions and excessive land use. As climate goals must be met and… Read More »Choices and Preferences for Living and Moving in a Suburban Car-Free Neighbourhood A Case Study in De Stationstuinen
