Topological road-boundary detection using remote sensing imagery plays a critical role in creating high-definition (HD) maps and enabling autonomous driving. Previous approaches follow an iterative graph-growing paradigm for road-boundary extraction, …
Illegal construction is a common problem often encountered by cities with rapid development, which is hard to deal with for multiple reasons. Although these illegal buildings are primarily defined by laws and regulations, they still have physical …
Efficient and effective multivariate time series (MTS) forecasting is critical for real-world applications, such as traffic management and energy dispatching. Most of the current deep learning studies (e.g., Spatio-Temporal Graph Neural Networks and …
The patterns of material accumulation in buildings and infrastructure accompanied by rapid urbanization offer an important, yet hitherto largely missing stock perspective for facilitating urban system engineering and informing urban resources, waste, …
Intra-urban origin-destination (OD) network communities evolve throughout the day, indicating changing groups of closely connected regions. Under such variation, groups of regions with high consistency of community affiliation characterize the …
The United Nations has proposed Sustainable Development Goals (SDGs), of which SDG11 aims to “make cities and human settlements inclusive, safe, resilient and sustainable”. This is in line with Urban Vitality's objectives. This study proposes a …
Active travel, namely walking and cycling, is an eco-friendly and socially beneficial mode of sustainable transportation. However, existing research on active travel relies on limited survey data and generalized linear models. To fill the gap, our …
Intercity population movement has been extensively studied since it is closely related to human society. Currently, city industry structures play dominant roles in the direction of population movement. Yet, the extent to which different kinds of …
The way humans travel and even their daily commute, is gradually expanding beyond the confines of counties and cities. Traffic between counties, cities, and even across the entire state is increasingly becoming a common aspect of daily activities. …
Real-time online trajectory map-matching has emerged as a critical component in the era of location-based services (LBS) and intelligent transportation systems (ITS). It refers to the process of aligning a user’s GPS trajectory data with the …
