 The data for this datasets are collected by experimental
-Bluetooth-based sensors and detectors and represent traffic
-information, since the detectors scan available Bluetooth devices on
-board of vehicle that drive on.
+Bluetooth-based sensors and detectors currently located on various
+points of the streets of Bolzano and soon in other location of South
+Tyrol. Gathered data are then processed to obtain useful information
+about the traffic; therefore, data in this dataset are:
 
+* The total number of vehicles detected
+* An estimation of heavy and light vehicles
+
+Collected data are also split within intervals (of e.g.,15, 30
+minutes), for statistical and historical offline analysis. Moreover,
+the data gathered by the Bluetooth devices are used in the
+:ref:`linkstation-dataset`.

-Similar to the :ref:`Bluetooth dataset <bluetooth-dataset>`, data
-available in this dataset are collected by Bluetooth-based sensors to
-measure the level of traffic on the strech of a road.
+The data for this dataset are collected by the same Bluetooth-based
+sensors that are used to produce the :ref:`Bluetooth dataset
+<bluetooth-dataset>`. Indeed, the data gathered by the sensors will be
+used to produce statistics about a LinkStation, which is defined as
+the shortest path between an ordered pair of bluetooth stations.
+
+* the :strong:`valid matches` between pairs of Bluetooth sensors (also
+  called Bluetooth stations).
+* The :strong:`number of matches per predefined time interval` (e.g.,
+  30 or 60 minutes), like in the Bluetooth dataset
+* The :strong:`estimated travel time and speed` of the vehicle, computed for
+  every 15 minutes interval only.
+
+The definitions and algorithm used in the computations are extensively
+described in Section `Data analysis complexity` of `this pdf article
+<https://www.integreen-life.bz.it/it/c/document_library/get_file?uuid=f1702bf2-5ed9-42a5-a85b-42a3d97a3e6b&groupId=17369>`_.
