From the dataset abstract

The data present car traffic volumes on Espoo's street and road network in spatial format. This is the average weekday (Mon to Fri) traffic volume (KAVL). It also shows the percentage of the daily traffic volume for the morning peak hour, evening peak hour, heavy goods vehicles and night-time traffic.

Espoo's traffic volumes are obtained from Viacount II and DSL10 counters and from the LAM portal. The most accurate results are always from the most recent census year and values after that are based on estimates.

You can preview the data in the Map Service of Espoo.
