Challenges, perceptions, and future preferences for post-secondary online education given experiences in the COVID-19 outbreak
Computational Urban Science - Tập 2 - Trang 1-15 - 2022
To gain a better understanding of online education status during and after the pandemic outbreak, this paper analyzed the data from a recent survey conducted in the state of Florida in May 2020. In particular, we focused on college students’ perception of productivity changes, benefits, challenges, and their overall preference for the future of online education. Our initial exploratory analysis sh......
Smart city based on digital twins
Computational Urban Science - Tập 1 - Trang 1-11 - 2021
Digital twins are considered to be a new starting point for today’s smart city construction. This paper defines the concepts of digital twins and digital twin cities, discusses the relationship between digital twins and smart cities, analyzes the characteristics of smart cities based on digital twins, and focuses on the five main applications of smart cities based on digital twins. Finally, we dis......

The impact of scale on extracting urban mobility patterns using texture analysis
Computational Urban Science - Tập 3 - Trang 1-19 - 2023
The development of high-precision location tracking devices and advancements in data collection, storage, transmission technologies, and data mining algorithms have led to the availability of large datasets with high spatiotemporal resolution. These geospatial big data can be used to identify human movement patterns in urban areas. However, identifying human movement patterns may yield different r......
A method to create a synthetic population with social networks for geographically-explicit agent-based models
Computational Urban Science - Tập 2 - Trang 1-18 - 2022
Geographically-explicit simulations have become crucial in understanding cities and are playing an important role in Urban Science. One such approach is that of agent-based modeling which allows us to explore how agents interact with the environment and each other (e.g., social networks), and how through such interactions aggregate patterns emerge (e.g., disease outbreaks, traffic jams). While the......
Enhanced Two-Step Virtual Catchment Area (E2SVCA) model to measure telehealth accessibility
Computational Urban Science - Tập 3 - Trang 1-13 - 2023
The use of telehealth has increased significantly over the last decade and has become even more popular and essential during the COVID-19 pandemic due to social distancing requirements. Telehealth has many advantages including potentially improving access to healthcare in rural areas and achieving healthcare equality. However, there is still limited research in the literature on how to accurately ......
Residential location choice: an investigation of transportation, public facilities, and social factors
Computational Urban Science - Tập 4 - Trang 1-17 - 2024
Residential location choice is a crucial topic in transportation planning research since land use as well as residential land use can significantly affect a city's attractiveness for development and residence. Understanding the factors that influence households in their residential location choice is essential for policymakers to evaluate the effect of their decisions. In this study, the impact of......
XStar: a software system for handling taxi trajectory big data
Computational Urban Science - Tập 1 - Trang 1-13 - 2021
Advances in positioning and communicating technologies make it possible to collect large volumes of taxi trajectory data, quickly providing a complete picture of the ground traffic systems and thus being applied to different fields. However, there are still challenges for data users to handle such big data. In view of this, we have developed a software system named XStar to deal with trajectory bi......
Emotional characteristics and theme mining of star-rated hotels from the perspective of social sensing: a case study of Nanchang City, China
Computational Urban Science - Tập 2 - Trang 1-12 - 2022
Mining hotel social sensing data and analyzing its spatial and temporal characteristics can provide decision support for hotel managers. Present research on this topic is limited to the overall hotel industry and text mining. Here, we first obtain POI and reviews for star-rated hotels in Nanchang from 2018 to 2021. Secondly, the hotel POI (Point of Interest) is combined with the sentiment value of......
Administrative level, city tier, and air quality: contextual determinants of hukou conversion for migrants in China
Computational Urban Science - Tập 1 - Trang 1-16 - 2021
Hukou reform and relevant policies are being implemented in current China, but the response of migrants to hukou conversion in destinations falls short of expectation. It is significant to understand how contextual factors in destination cities affect migrants’ willingness of hukou conversion. Considering administrative dimension, socio-economic dimension, and environmental dimension, this study f......
Assessing the safety effect of red-light camera deactivation: a geographically weighted negative binomial regression approach
Computational Urban Science - Tập 2 - Trang 1-12 - 2022
Municipalities across the country have debated the safety effect of automatic red-light cameras (RLC) and their political and financial implications. Most empirical studies have used the Empirical Bayesian (EB) approach to assess the safe effects to facilitate policy debates. While popular, the EB method has several limitations in data requirement, reference site selection, and control of confound......
