%description
Estimate and return either the traffic speed or the car entries in the
city of Thessaloniki using historical traffic data. It's used in transport
pilot of the 'BigDataEurope' project. There are functions for processing
these data, training a neural network, select the most appropriate model
and predict the traffic speed or the car entries for a selected time date.
