1. A processing apparatus for generating route navigation data, comprising a processor and a memory, the apparatus being configured, under control of the processor to execute instructions in the memory to:
generate training data based on road network data corresponding to a network of roads in a defined geographical area, journey data sets, each journey data set comprising data indicative of a journey made by a road user through the network of roads and being derived using geolocation transmissions from a communications device of the road user, road data sets, the road data sets generated from the road network data and the journey data sets, for each road data set, the road data is associated with a specific road in the network of roads in the road data set, and entropy data indicative of an entropy in a direction of traffic flow on the respective road, wherein the entropy data is derived from the journey data sets;
train a classifier model based on the training data;
apply the trained classifier model on road data corresponding to a road in the defined geographical area, for the trained classifier model to predict a direction of traffic flow on the road; and
generate the route navigation data indicative of the predicted direction of the traffic flow on the road.
