It contains GPS coordinates of approximately 500 taxis collected over 30 days in the San Francisco Bay Area. Cab mobility traces are provided by the Exploratorium - the museum of science, art and human perception through the cabspotting project: http://cabspotting.org . Cabspotting is designed as a living framework to use the activity of commercial cabs as a starting point to explore the economic, social, political and cultural issues that are revealed by the cab traces. Where do cabs go the most? Where do they never turn up? Cab Projects are vehicles for artists, writers, or researchers to explore these issues in the form of a small experiment, investigation or observation.Cab mobility traces are provided by the Exploratorium - the museum of science, art and human perception through the cabspotting project: http://cabspotting.org . "Each San Francisco based Yellow Cab vehicle is currently outfitted with a GPS tracking device that is used by dispatchers to efficiently reach customers. The data is transmitted from each cab to a central receiving station, and then delivered in real-time to dispatch computers via a central server. This system broadcasts the cab call number, location and whether the cab currently has a fare."(*) You can use this data set of cab mobility traces that were collected in May 2008. (*) http://cabspotting.org/about.htmlEach taxi is equipped with a GPS receiver and sends a location-update (timestamp, identifier, geo-coordinates) to a central server. The location-updates are quite fine-grained - the average time interval between two consecutive location updates is less than 10 sec, allowing us to accurately interpolate node positions between location-updates.Out of respect for the privacy of cab drivers and customers, no direct access to cab data with identifiable cab numbers is provided to the public. The project emphasizes the analysis of aggregate data and data patterns, with most of this analysis happening on historic data and larger data patterns using scrambled cab numbers.83200902242009-02-19the initial version.epfl/mobility/cabTraceset of mobility data of taxi cabs in San Francisco, USA.

Our system talks to the Yellow Cab server and stores the data in a database, encoding the call number for privacy. Server-side processes computer the aggregate map at various time intervals (10 minute, 1 hour, 8 hours, etc.) and store these frames as Postscript and bitmap images. These are subsequently combined into movies for every day, week, etc. Images and movies can be queried by visitors to the site in the Time Lapse area. A sample of real-time data overlaid on the most recent map can be seen in the Cab Tracker client. You can collect your own cab mobility traces following the instructions from http://cabspotting.org/api ./download/epfl/mobility/cabspottingdata.tar.gzepfl/mobility272200902242009-02-19the initial versionepfl/mobility/cab/may_2008Mobility traces of taxi cabs in San Francisco, USA.
