  • 隨著人口的激增和繁忙的城市生活方式,預測個人出行的能力對於公共交通管理,動態系統操作和個性化出行推薦至關重要。但是,大多數現有方法側重於預測人流或目的地,而我們則側重於個人旅程並且同時解決雙系統(捷運與巴士系統)轉乘。在本文中,我們提出了一種方法,可以預測單個乘客的下一次行程(進站位置o,目的地d和目前出站時間到下一次行程t的持續時間)。為了預測單個乘客的下一次行程,我們將其分解為兩個小問題,即1.預測目的地d以及2.預測下一個o和持續時間t。首先,對於目的地d的預測,我們將單個行程分為常規行程和不規則行程,並提出了要解決的個人和組模塊。其次,預測下次進站點o和持續時間t上,我們提出了一個雙系統模組,該模組可以同時預測捷運和巴士系統的下一次行程。

    Individual trip prediction is crucial to the management of public transport and personalized trip recommendation systems; however, most existing methods focus on passenger flow or the destination. In the current study, we focus on two problems pertaining to the prediction of trips for individual users: (1) Predicting the destination of the current trip when it is first initiated; and (2) predicting when and where the next trip will be initiated. We employed smart card data as well as several trip features. In preprocessing, we grouped users by these trip features. To predict the destination of the current trip, we first classify the current trip as regular or irregular. Regular cases are examined using historical data at the individual level, whereas irregular trips are examined using data at the group level. To predict the interval to the next trip and corresponding trip origin, we first predict the transport system the user will employ (BRT or MRT) and then use group-level historical data pertaining to that transport system. Extensive experiments on real datasets demonstrate that in terms of prediction accuracy the proposed scheme outperforms existing state-of-the-art systems.
