Taxi Flow is a little scraping project, in which I monitored the position data of taxis in different cities for one week in October 2012. The datasource was a popular taxi ordering website.
The video captures the rhythm in which the taxis flow through the city. Especcially the congested streets during rush hours are clearly visible.

I compared the average speed between three different cities. It is interesting to see that the overall rhythm is quite similar to each other.
