Identifying travel modes from massive information is critical for travel demand modeling and transportation planning. Along with widespread application of the highly accurate position devices, the need of cost-effective approaches is more urgent than ever before. In the field of movement ecology, it has been proved by experiments that Hidden Markov Model (HMM) is much more efficient than traditional statistical classification method, such as Bayesian methods. Accordingly, in this paper, the Hidden Markov Model is adopted to predict travel modes based on raw GPS trajectories, where the modes are labeled as walk, bike, bus, and driving. Besides, this study also endeavors to examine the inherent statistical characteristics of trajectories in different modes, and identify the relationship between residents’ choice of travel mode and the traffic flow structure along the route. The data analysis results are believed to gain a deeper insight into the impact of distance and route on residents’ choice of travel mode, and it is expected to provide ideas and references for the transportation planning of cities with completed transportation infrastructure construction.
