With the advent of ubiquitous computing, we can easily collect large scale trajectory data from moving vehicles. This paper presents TPM (Trajectory Pattern Miner), a software aimed at pattern matching queries for road-network trajectory data, which complements existing efforts focusing on (a) a spatio-temporal window query for location-based service or (b) Euclidean space with no restriction. To overcome limitations of prior research, TPM supports three types of pattern matching queries-- whole, subpattern, and reverse sub-pattern matching for road-network trajectories. We demonstrate application scenarios for each type of pattern matching queries using large-scale real-life trajectory data.
