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.
