Title : Clustering and aggregating clues of trajectories for mining trajectory patterns and routes

Purpose : For discovering trajectory routes that represent the frequent movement behaviors of a user.

Clue-aware trajectory aggregation algorithm (CACT): To aggregate trajectories in the same group to derive the corresponding trajectory pattern and route.

CACT consists of three algorithm:

1. clue-aware trajectory similarity (CATS)
2. clue-aware trajectory clustering (CATC)
3. clue-aware trajectory aggregation(CATA)
