The analysis of vehicle’s GPS traces such as taxis can help better understand urban mobility and flow. In this paper we present a spatiotemporal analysis of taxis GPS traces collected in Lisbon, Portugal during the course of five month. We also show that trip distance can be represented with a Gamma distribution, and discuss the taxi driving strategies and respective income.

Abstract Vehicles equipped with GPS localizers are an important sensory device for
examining people's movements and activities. Taxis equipped with GPS localizers serve the
transportation needs of a large number of people driven by diverse needs; their traces can ...
Visual exploration of big spatio-temporal urban data: A study of new york city taxi trips
N Ferreira, J Poco, HT Vo, J Freire… - … and Computer Graphics …, 2013 - ieeexplore.ieee.org
Abstract—As increasing volumes of urban data are captured and become available, new
opportunities arise for data-driven analysis that can lead to improvements in the lives of
citizens through evidence-based decision making and policies. In this paper, we focus on ...
Yellow cabs as red corpuscles
TH Savage, HT Vo - Big Data, 2013 IEEE International …, 2013 - ieeexplore.ieee.org
Abstract—Data obtained from New York City's Taxi & Limousine Commission highlights the
importance of yellow cabs in the city's transportation infrastructure. In 2011, for example,
there were nearly 180 million cab rides. In this paper, we provide detailed visualizations of ...
Unraveling the origin of exponential law in intra-urban human mobility
X Liang, J Zhao, L Dong, K Xu - arXiv preprint arXiv:1305.6364, 2013 - arxiv.org
Abstract: The vast majority of travel takes place within cities. Recently, new data has become
available which allows for the discovery of urban mobility patterns which differ from
established results about long distance travel. Specifically, the latest evidence ...

As a significant factor in urban planning, traffic forecasting and prediction of epidemics,
modeling patterns of human mobility draws intensive attention from researchers for decades.
Mining the semantics of origin-destination flows using taxi traces
W Zhang, S Li, G Pan - Proceedings of the 2012 ACM Conference on …, 2012 - dl.acm.org
Abstract Origin-destination (OD) flows reflect both human activity and urban dynamic in a
city. However, our understanding about their patterns remains limited. In this paper, we study
the GPS traces of taxis in a city with several millions people, China and find that there are ...

from data obtained from surveys. Nevertheless, such approaches typically involve high ...
Modeling collective human mobility: Understanding exponential law of intra-urban movement
X Liang, J Zhao, L Dong, K Xu - arXiv preprint arXiv:1212.6331, 2012 - arxiv.org
Abstract: It is very important to understand urban mobility patterns because most trips are
concentrated in urban areas. In the paper, a new model is proposed to model collective
human mobility in urban areas. The model can be applied to predict individual flows not ...
