Dataset: citypulse-traffic-graphs (development version)

This is a variation of the citypulse-traffic dataset that was transformed into a stream of graphs, compliant with the RSP Data Model. The dataset is a processed subset of real traffic data published by the CityPulse EU FP7 project. The used dataset is 'Road Traffic Data', dataset-4. The dataset was processed to fix prefixes without a trailing '#' or '/'. It consists of subsequent chronologically ordered substreams of observations from each sensor. See also the paper for more details.

This README is a snapshot of documentation for the latest development version of the dataset. Full documentation for all versions can be found on the website.
