Try connecting sequences of t,x,y for each device_id in the training and test sets and record a single trip_id for the whole sequence. The nominal time span might be a minute or a few (GPS locations are recorded every 5 seconds). This could be used for basic KNN, and also perhaps for KNN with DTW for measuring distance between sequences (though DTW doesn't satisfy the triangle inequality).
