Orange Data for Development is an open data challenge, encouraging research teams around the world to use four datasets of anonymous call patterns of Orange's Ivory Coast subsidiary, to help address society development questions in novel ways. The data sets are based on anonymized Call Detail Records extracted from Orange's customer base, covering the months of December 2011 to April 2012.
Our team used the geolocation data from call detail records extracted from Orange's customer base in order to know in which areas the customers have been moving around, to help us discover the morning and evening rush hours: the time when users were commuting between their place of residence and place of work.
Visualization
We used Python for crunching the numbers and D3.js for creating the visualization.
Bar Chart
The bar chart shows the total population density at a fixed time slot. Rush hours can be identified by the two peaks that emerge every day, one in the morning and one in the afternoon.
Choropleth
The choropleth shows how the population density flows over time, as people move from one region to another. Notice how the density increases (areas get darker) as the time gets closer to the rush hours.
