签到行为的可预测性及影响因素分析

人类日常的出行行为受到多种因素的制约和影响。本文通过两组手机用户上报的位置信息分析人类签到行为的空间规律特征,着重分析了访问地点数、平均跳转距离、回转半径和最常访问地点等因素对签到行为的可预测性的影响。研究表明签到行为具有一定的记忆性,用户访问的地点数、对最常访问地点的访问规律是影响可预测性和规律性的主要因素,用户的活动范围和平均跳转距离对可预测性的影响则微弱得多。

Predictability and Influential Factors on Check-in Behaviors

The human mobility pattern in ordinary life is influenced by various factors. Two datasets of location information reported by mobile phones are utilized to analyze the spatial mobility pattern of check-in behavior. Our research focuses on the impacts of the numbers of visited locations, average jump distances, radiuses of gyration and most frequent visited locations on the predictability of check-in behavior. It is found that the check-in behavior shows certain memory effect. The numbers of visited locations and the visiting patterns to the most frequent visited locations have more significant influence on the predictability and regularity of check-in behavior, meanwhile the impacts of radiuses of gyration and the average jump distances are obviously unremarkable.
