Paris metro is over a hundred years old and the first lines were built when the city extended little behind its administrative border. Today Paris is a metropolis of over 12 millions inhabitants, among those only 2.2m live in the city proper. The metro has expanded into its suburbs and further expansions are planned.
However travelling accross Paris with the metro can be slow due to the density of stations: the average distance between stations is 570 meters compared to 1200m for the world average and the average commercial speed across the network is only 27km/h. As a consequence trains almost never reach their maximum speed. For example it takes 52 minutes on line 9 to cover the 19.5km between Pont de Sèvre and Montreuil compared to 29 minutes for the Victoria line in London for 21km.
This project is meant to open the discussion on a way to make Paris metro more efficient and provide a new point of view on the topic based on data. Suggestions are welcome!
