Fast and Scalable Big Data Trajectory Clustering for Understanding Urban Mobility.
IEEE Transactions on Intelligent Transportation Systems(2018)
摘要
Clustering of large-scale vehicle trajectories is an important aspect for understanding urban traffic patterns, particularly for optimizing public transport routes and frequencies and improving the decisions made by authorities. Existing trajectory clustering schemes are not well suited to large numbers of trajectories in dense city road networks due to the difficulty in finding a representative d...
