#BSS, #OPENDATA, #DATAVIZ

This application offers an access to historical data about some twenty BSS systems, such as Paris, London or New-York at different temporal and spatial scales. It was developped at ifsttar during a research project on BSS data analysis: we think that an historical vision is mandatory to better analyze, understand and eventually enhance these systems. The open-data movement has lead an increased number of city to open real time stock data (see jcdecaux open data site for examples). We therefore take this opportunity to build an historical database where these real time data are recorded. This site is a first attempt to visualize these data, it is organized around three views offering the possibility to compare the systems, to observe a city more closely or a given station. The recorded cities are for the timebeing:

City comparison

This map allows to compare the systems performances indicators. These indicators correspond to monthly statistics on different system aspects: size, usage, performances, saturation, ... Click on a stat to compare the systems on the map, hover a city to get details and click to access the city detailed view.

City dash-board

This view offers the opportunity to study the last-week behavior of a city. Click on a stat to see its temporal and spatial behavior. Hover a station to know its state and clik to get further details.

eventually, explore the history using the , arrows of our keyboard.

Station dash-board

This view offers the opportunity to explore the recent history of a station data. The map shows the states of neighborhood stations. The first graph shows the temporal behavior of the selected statistic: available bikes, available docks and broken docks. The second graph shows the same information with a circular layout in order to highlight a possible regularity in station usage.
