Vehicular traffic count measurements utilized in “Origin-destination matrix estimation with a conditionally binomial model” by P.Kuusela, I. Norros, J. Kilpi, and T. Räty

Description of inductive loop vehicular traffic count measurements from Tampere City, Finland
Locations: Tampere City, Finland measurement points at Santalahti (approximately 61°30'30.8"N 23°41'50.7"E) and Tampella (approximately 61°30'12.3"N 23°45'28.9"E) on Finnish national road 12
A map of selected road loop measurement locations at Tampere City, the city centre is located at the centre  -right of the map. Red dots indicate measurement locations. A larger set of data may be published in the future. 

Permission to publish:  The estimation data is calculated by InfoTripla company located at Tampere, Finland. Permission to publish this data has been obtained from InfoTripla. InfoTripla has processed open data on Tampere traffic (for the Stomograph Project financed by the Academy of Finland).

Editors of the data: Pirkko Kuusela and Jorma Kilpi, VTT Technical Research Centre of Finland
Date of publication: Dec 2018
Duration: 2011 – 2014
Numerical data:
1)	Time stamps of the end time of 15-minute measurement periods
2)	Number of vehicles that passed by a measurement point. This value counts vehicles on all lanes and the estimated value is calculated by using (in many times) several loop detectors at varying distances from an intersection. Estimation algorithm combines also several shorter time period estimates.

Entries:
1.	{2011, 1, 1, 0, 15, 0}: {year, month, day, hour, minute, second}
a.	The end time of a 15-minute measurement period
2.	224: Number of vehicles at Santalahti driving from West to East (towards city)
3.	244: Number of vehicles at Santalahti driving from East to West (out of city)
4.	216: Number of vehicles at Tampella driving from East to West (towards city)
5.	184: Number of vehicles at Tampella driving from West to East (out of city)
Note that vehicle counts at a measurement point are listed as “towards city” and “out of city”, so compass points are different at Santalahti and Tampella.
