Yang Wu, Junhua Fang, Wei Chen, Pengpeng Zhao, Lei Zhao

Abstract: Highlights•Seamless fusion of trajectory outlier detection based on spatial and feature for the first time.•LCAF and evolutionary decay function are introduced to achieve fine-grained trajectory outlier detection.•Integrate the framework into a distributed environment to improve execution efficiency.
