Scale‐oriented temporal analysis of movement data: A series‐based approach

Pengdong Zhang, Nico Van de Weghe

Transactions in GIS > 27 > 8 > 2234 - 2251

The ubiquity of movement data has led to new research interest in aspects of temporal scale. Few of the approaches analyzing movement data have been developed specifically for scale‐oriented temporal analysis. To overcome this limitation, this article proposes a series‐based approach to perform scale‐oriented temporal analysis of movement data. Key to the proposed approach is the construction of four...

Jan M. Baert, Eric W. M. Stienen, Frederick Verbruggen, Nico Van de Weghe, more

Oikos > 130 > 8 > 1272 - 1283

Individual niche variation is common within animal populations, and has significant implications for a wide range of ecological and evolutionary processes. However, individual niche differences may also temporally vary as a result of behavioural plasticity. While it is well understood how niche variation is affected by changes in resource availability, comparatively little is known about the extent...

Dynamic assessment of exposure to air pollution using mobile phone data

Bart Dewulf, Tijs Neutens, Wouter Lefebvre, Gerdy Seynaeve, more

International Journal of Health Geographics > 2016 > 15 > 1 > 1-14

Background Exposure to air pollution can have major health impacts, such as respiratory and cardiovascular diseases. Traditionally, only the air pollution concentration at the home location is taken into account in health impact assessments and epidemiological studies. Neglecting individual travel patterns can lead to a bias in air pollution exposure assessments. Methods In this work, we present...

Which environmental factors most strongly influence a street’s appeal for bicycle transport among adults? A conjoint study using manipulated photographs

Lieze Mertens, Delfien Van Dyck, Ariane Ghekiere, Ilse De Bourdeaudhuij, more

International Journal of Health Geographics > 2016 > 15 > 1 > 1-14

Background Micro-environmental factors (specific features within a streetscape), instead of macro-environmental factors (urban planning features), are more feasible to modify in existing neighborhoods and thus more practical to target for environmental interventions. Because it is often not possible to change the whole micro-environment at once, the current study aims to determine which micro-environmental...

Differences in environmental preferences towards cycling for transport among adults: a latent class analysis

Lieze Mertens, Jelle Van Cauwenberg, Ariane Ghekiere, Ilse De Bourdeaudhuij, more

BMC Public Health > 2016 > 16 > 1 > 1-10

Background Increasing cycling for transport can contribute to improve public health among adults. Micro-environmental factors (i.e. small-scaled street-setting features) may play an important role in affecting the street’s appeal to cycle for transport. Understanding about the interplay between individuals and their physical environment is important to establish tailored environmental interventions...

QTC3D: Extending the qualitative trajectory calculus to three dimensions

Nikolaos Mavridis, Nicola Bellotto, Konstantinos Iliopoulos, Nico Van de Weghe

Information Sciences > 2015 > 322 > Complete > 20-30

Spatial interactions between agents (humans, animals, or machines) carry information of high value to human or electronic observers. However, not all the information contained in a pair of continuous trajectories is important and thus the need for qualitative descriptions of interaction trajectories arises. The Qualitative Trajectory Calculus (QTC) (Van de Weghe, 2004) is a promising development towards...

Veerle Van Holle, Jelle Van Cauwenberg, Benedicte Deforche, Liesbet Goubert, more

Transportation Research Part A: Policy and Practice > 2014 > 69 > C > 432-446

Current evidence on associations between modifiable environmental characteristics and transport-related cycling remains inconsistent. Most studies on these associations used questionnaires to determine environmental perceptions, but such tools may be subject to bias due to unreliable recall. Moreover, questionnaires only measure separate environmental characteristics, while real environments are a...

Time‐geographic Derivation of Feasible Co‐presence Opportunities from Network‐constrained Episodic Movement Data

Mathias Versichele, Tijs Neutens, Manuel Claeys Bouuaert, Nico Van de Weghe

Transactions in GIS > 18 > 5 > 687 - 703

Certain datasets on moving objects are episodic in nature – that is, the data is characterized by time gaps during which the position of the object is unknown. In this article, a model is developed to study the sparsely sampled network‐constrained movement of several objects by calculating both potential and feasible (i.e. more likely) co‐presence opportunities over time. The approach is applied to...

Evaluating suitability of the least risk path algorithm to support cognitive wayfinding in indoor spaces: An empirical study

Ann Vanclooster, Kristien Ooms, Pepijn Viaene, Veerle Fack, more

Applied Geography > 2014 > 53 > Complete > 128-140

Over the last couple of years, applications that support wayfinding in indoor spaces have become a booming industry. Finding one's way in complex 3D indoor environments can still be a challenging endeavor, partly induced by the specific indoor structure (e.g. fragmentation, less visibility, confined areas). Appropriate algorithms that help guide unfamiliar users by providing ‘easier to follow’ route...

Representing time intervals in a two-dimensional space: An empirical study

Yi Qiang, Martin Valcke, Philippe De Maeyer, Nico Van de Weghe

Journal of Visual Languages and Computing > 2014 > 25 > 4 > 466-480

Instead of the linear model (LM), time intervals can be represented by a two-dimensional (2D) model, which is called the triangular model (TM). Although the TM has been introduced for decades and applied in some areas, there still a lack of empirical studies on its usability. To fill this gap, this study aims to evaluate how people perform when using the TM to answer questions on time intervals, in...
