LondonBike Dataset - complementary code for "Community structures, interactions and dynamics in London's bicycle sharing network"
This repository contains the complementary code for the paper "Community structures, interactions and dynamics in London's bicycle sharing network" (arXiv:1804.05584). This includes the code for data preparation, processing and creation of figures (all done in R) as well as the data analysis (done using Infomap). We also provide the generated network dataset and the output dataset (community assignment) from the community detection analysis. These can be found in the /data/ folder. The network edgelists are also hosted on the Index of Complex Networks at CU Boulder.
Our community detection using the Louvain algorithm, Greedy modularity maximization and Random walks is done with R (v3.4.2) using the igraph package. These analyses can be found in the /R/ folder.
The Infomap community detection is done using version v0.19.3. Instructions on how to run Infomap on your machine can be found here.
Once initialized, we create an output directory:
#create output directory
mkdir outputtest
We then run Infomap with the following settings:
#run infomap (given valid edges.txt input)
./Infomap edges.txt outputtest/ -N 20 --tree --map --directed #--include-self-links if needed
Where the edges.txt file is either the aggregated OD-matrix /data/edges.txt or the 1h interval matrices from /data/edges_per_hour/edges{0,...,23}.txt.
