Taxi Trips in Beijing

Animating taxi trajectory data collected in Beijing

About

This project represents my attempt to visualize a "bird's eye view" of Beijing taxi flows using publicly available data.

The underlying data was collected and made public by Microsoft Research.

Methodology:

I downloaded the Beijing taxi trajectory data from Microsoft Research and selected just one day to visualize. I wrote a python script to parse the data into a table, relying heavily on the GeoPandas library.

I then wrote an application using OpenFrameworks (C++) to visualize the data. Here is a video showing the animation created with openFrameworks:

I then wanted to add a blur effect, so that the visualization would resemble flame (rather than displaying individual dots moving). So, I used Touchdesigner to apply a GLSL filter. Here is the video showing the animation after post-processing in TouchDesigner:

Tools used: Python, openFrameworks (C++), TouchDesigner
