Exploratory Study of Urban Flow using Taxi Traces



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.

X Liang, J Zhao, L Dong, K Xu - arXiv preprint arXiv:1212.6331, 2012 -
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 ...
