Relating Land Use and Human Intra-City Mobility

Minjin Lee, Petter Holme, Renaud Lambiotte
2015 PLoS ONE  
In this paper, we discuss how the intra-city movement patterns, and consequently population distribution, can be predicted from such data sources.  ...  As a link between land use and mobility, we show that the purposes of people's trips are strongly correlated with the land use of the trip's origin and destination.  ...  Acknowledgments The authors thank Sang Hoon Lee for helpful comments and help with the location mapping.  ...

Fractals in urban geography: a theoretical outline and an empirical example

Cécile Tannier, Denise Pumain
2005 CyberGeo  
This reflects two different ways of structuring geographical space, for different purposes in terms of location and interaction, the intra-urban organisation of activities on the one hand and inter-urban  ...  The rapidity of this decrease is however regular and is measured by parameters (b in the exponential model, a in the Pareto model) which have constant value for all the urban structures.  ...

Urban Research and Complexity [chapter]

Denise Pumain
1998 The City and Its Sciences  
The models exploring how a variety of urban forms can be generated from deterministic nonlinear equations are mainly models of intra-urban structures.  ...  For instance, the concept of density for urban residential population or land use is not perhaps relevant to a real understanding of an urban aggregate of population and buildings, whereas the concept  ...

The role of spatial metrics in the analysis and modeling of urban land use change

Martin Herold, Helen Couclelis, Keith C. Clarke
2005 Computers, Environment and Urban Systems  
The paper explores a framework combining remote sensing and spatial metrics aimed at improving the analysis and modeling of urban growth and land use change.  ...  We claim that the proposed approach leads to an improved understanding and representation of urban dynamics and helps to develop alternative conceptions of urban spatial structure and change.  ...  Acknowledgements This work was conducted with support from the National Science Foundation under UCSB's Urban Research Initiative's project UCIME (Award NSF-9817761).  ...

Discovering urban spatial-temporal structure from human activity patterns

Shan Jiang, Joseph Ferreira, Marta C. Gonzalez
2012 Proceedings of the ACM SIGKDD International Workshop on Urban Computing - UrbComp '12  
Urban geographers, planners, and economists have long been studying urban spatial structure to understand the development of cities.  ...  It will be helpful for planers to understand how individuals utilize time and interact with urban space in metropolitan areas and crucial for the design of sustainable cities in the future.  ...  For decades, urban spatial structure, measured by the degree of spatial concentration of population and employment, has been studied by urban scholars to describe the structure and organization of cities  ...

Analyzing the Spatial Heterogeneity of the Built Environment and Its Impact on the Urban Thermal Environment—Case Study of Downtown Shanghai

Jiejie Han, Xi Zhao, Hao Zhang, Yu Liu
2021 Sustainability  
Ongoing urban expansion has accelerated the explosive growth of urban populations and has led to a dramatic increase in the impervious surface area within urban areas.  ...  The aim of this study was to quantitatively explore the relationship between the spatial heterogeneity of a built environment and the intra-urban surface heat island (intra-SUHI) effect using the thermally  ...  At present, global urban areas house more than 50% of the total population and 70-90% of all economic activities [4] , resulting in unprecedented urban expansion and explosive growth of urban populations  ...

Cellular Models of Urban Systems [chapter]

David O'Sullivan, Paul M. Torrens
2001 Theory and Practical Issues on Cellular Automata  
Cellular automaton (CA) based models are increasingly used to investigate cities and urban systems.  ...  First, for operational model-building many variations on the CA theme are required and should be welcomed; and second theoretically motivated variations of the CA formalism are required so that the possible  ...  The idea of the cell state may become a more or less complex classification of land uses, land values, land covers, population densities, and so on.  ...

Green-Roof Effects on Neighborhood Microclimate and Human Thermal Sensation

Lilliana Peng, C. Jim
2013 Energies  
Previous studies have identified green-roof benefits in cooling and energy-conservation at the building scale, with limited exploration of the wider influence on neighborhood microclimate and human thermal  ...  The findings indicated that large-scale green-roof installation could bring neighborhood-wide cooling, mitigate urban heat island effect, and furnish more comfortable thermal environment for urban residents  ...  Acknowledgements We acknowledge with gratitude the research grant supports generously provided by the  ...
