This video was generated in Unity3d to visualise the trips made by disabled freedom pass holders on the London Underground network. The bright orange streaks represent disabled freedom pass users, whereas the smaller white trails represent other users.
The data is courtesy and copyright of Transport For London, and is drawn from a 5% sample in the month of November, 2009. The individual trips were solved for shortest paths between the origin and destination stations using Python's numpy and scipy.csgraph packages. The data was then imported, scripted, and visualised in Unity.
