中文摘要	基于用户的历史轨迹数据,对用户的规律路径进行挖掘和提取。在轨迹预处理和聚类的基础上,定义了支撑路径的概念,提出了一种基于支撑得分的规律轨迹挖掘算法。并通过规律停止率特征,提高了对轨迹交通模式识别的准确率。基于178名用户4年的GPS轨迹记录,以及37名用户的实际轨迹数据,开展了用户试验。结果表明,本文算法能够有效地提取用户的规律路径,并对路径中的干扰具有一定的鲁棒性。; Based on users' historical trajectory data,users' regular routes were mined and extracted.A concept of support route was defined after route pre-processing and grouping.A regular route mining algorithm was proposed based on the support score.A feature of Regular Stop Rate(RSR)was used to improve the accuracy of the transportation mode recognition.The effectiveness of the approach was validated based on the GPS data of 178 users over four years.A real user study was also performed among 37 users.The experiment results demonstrate that the algorithm can effectively extract the regular routes and is robust to slight disturbance in trajectory data.
