Reverse journey matching for smartcard transaction data

Enrich smartcard transaction data to assign bus stop locations and direction of travel to data. The data used in this example is generated from timetable data using the code in dummy_trans_from_tt.R

I have written code that assigns an array of possible stops to each transaction that it is possible to assign a direction of travel to. This means, each "journey" of a machine/bus for which there is more than one transaction available that have different fare stages. The method also compares how similar to the timetable the pattern of transactions are. I will test the accuracy of the methods by comparing against the data for which GPS locations are available.
