BSS (Bike Sharing System) are very famous today as they are used in more than 400 towns all over the world. However BSS, in particular Vélib, still has some major problems, consisting mainly of finding no bike or no free place in the station when a user wants to take or park a bike.
The objective of the project is to propose new methods to improve the availability of the Vélib system resources. The final goal is to increase user satisfaction and reliability of Vélib. To achieve this goal, it is essential today to ensure a better distribution of bikes between stations by compensating the heterogeneity caused by the strong attraction (proximity to a railway station or to a monument…) of certain areas or the high altitude in other areas.
Two fields of research will be explored: First, we will propose technical incentives to encourage users to take bikes in the most populated stations and place them in the most empty. Then we will focus on the redistribution of bikes between the stations using trucks.
We are now analyzing data issued from Vélib system in order to quantify and well understand the usage of Vélib system today. We noticed many periodicities related to human daily activity. The stations can also be classified into several categories (clusters) according to their attractively (residential area, working area, parks, railway station…)
