摘要:

乘客行为预测旨在通过历史上下车数据追踪乘客出行模式,支撑城市站点客流分析与及时风险管理,对智慧城市发展和公共交通规划至关重要。现有研究主要依赖统计方法和序列模型从个体历史交互中学习,忽略了乘客与站点之间的关联。为解决这些问题,本文提出DyGPP(动态图乘客预测模型),利用动态图捕捉乘客行为的复杂演化。首先,将乘客和站点形式化为动态图中的异质顶点,顶点间的连接代表乘客与站点的交互;随后分别对乘客和站点的历史交互序列进行采样,从个体序列中捕捉时间模式,并关联两类序列间的时间行为;最后使用基于MLP(多层感知机)的编码器学习交互中的时间模式,生成乘客与站点的实时表示。在真实世界数据集上的实验证实,DyGPP在行为预测任务中优于现有模型,证明了该模型的优越性。

英文摘要:

Passenger behavior prediction aims to track passenger travel patterns through historical boarding and alighting data, enabling the analysis of urban station passenger flow and timely risk management. This is crucial for smart city development and public transportation planning. Existing research primarily relies on statistical methods and sequential models to learn from individual historical interactions, which ignores the correlations between passengers and stations. To address these issues, this paper proposes DyGPP, which leverages dynamic graphs to capture the intricate evolution of passenger behavior. First, we formalize passengers and stations as heterogeneous vertices in a dynamic graph, with connections between vertices representing interactions between passengers and stations. Then, we sample the historical interaction sequences for passengers and stations separately. We capture the temporal patterns from individual sequences and correlate the temporal behavior between the two sequences. Finally, we use an MLP-based encoder to learn the temporal patterns in the interactions and generate real-time representations of passengers and stations. Experiments on real-world datasets confirmed that DyGPP outperformed current models in the behavior prediction task, demonstrating the superiority of our model.
