摘要(Abstract)：

拥挤现象是困扰公共交通出行者和管理者的一个重要问题。公共交通出行者需要了解公共交通载具的负载情况从而尽可能地避免拥挤,公共交通管理者需要了解公共交通的客运情况来指挥调度。为了服务于以上需求,该文参考自由轨迹的群组定义方式定义了一种在公共交通系统中与拥挤现象强相关的群组模式,并重点给出了包含原始群组提取和融合原始群组在内的群组模式挖掘算法。基于提取到的群组进一步设计了群组的可视化方法。最后基于深圳地铁智能卡数据对地铁群组进行了模式挖掘与可视化。基于提取到的群组,乘客可以错峰出行,提高出行舒适度;交通规划者可以对拥挤易发生的路段进行调度。

关键词(KeyWords)： 智能卡数据;出行链;群组模式;可视化
