    Using Twitter to Estimate the Dynamics of Activities and Travel Demand

    Posted on Tuesday 1 July 2014 by vassilis zachariadis

    Recently a couple of colleagues (Ying Jin and Steve Denman) and I have been exploring the potential of geo-located tweets in understanding spatiotemporal urban dynamics. The analysis is based on a passively generated dataset containing 25 millions geo-…

    Spatiotemporal patterns and the dynamics of the city

    Posted on Wednesday 5 December 2012 by vassilis zachariadis

    One more post on GPS traces from taxis, this time from San Francisco. The video follows the origins (green dots) and destinations (red dots) of passenger trips made by taxi in San Francisco. It is based on GPS traces from 500 taxis over a full month.&n…

    3D simulation with JMonkeyEngine 3.0

    Posted on Friday 30 November 2012 by vassilis zachariadis

    I have been looking for a reasonable high level 3D library for Java for some time. Recently I have been using JME 3.0 (www.jmonkeyengine.org) and it seems to be doing the trick. Here are a couple of pics, one from an accessibility model of Cambridge, U…

    GPS traces of Taxis in Beijing

    Posted on Friday 30 November 2012 by vassilis zachariadis

    Last couple of weeks I have been playing around with a dataset of taxi GPS traces from Beijing. This includes positions and timestamps from 10.000 individual taxis for a week. Here is a map of speeds (red low, green high). It has been created by c…
