+This repository contains three datasets about road attributes in Finland,
+from Digiroad: https://aineistot.vayla.fi/spa/ava/Tie/Digiroad/
+
+The first of these is public_transport_stops.csv, which contains information on
+locations and types of public transport, e.g. bus stops.
+It contains 95803 data points.
+
+The second dataset is called highway_service_areas.csv which contains information
+on parking areas and their locations and types, along Finnish roads. 
+It contains 3182 data points.
+
+The third dataset is called speed_limits.csv and it contains information on speed
+limits, their locations and values (km/h). 
+It contains 74733 data points.
+
+The speed limits dataset could be used to model the traffic and highway areas, 
+as highways have larger speed limit values. The highway stops could be used in 
+combination to find candidate charging station locations and help decide whether
+to use fast or slow charging.
