摘要:

行程时间估计是一项关键任务,对公民个人和利益相关者层面的许多城市应用都很有用。本文提出了一种新的混合算法行程时间估计,利用历史和稀疏的实时轨迹数据。给定路径和出发时间,我们估计行程时间考虑到历史信息,实时轨迹数据和不同路段之间的相关性。我们使用历史轨迹来检测相似的路段,并使用潜在的表示来建模的相似性。我们的实验评估证明了我们的方法的有效性。

英文摘要:

Travel time estimation is a critical task, useful to many urban applications at the individual citizen and the stakeholder level. This paper presents a novel hybrid algorithm for travel time estimation that leverages historical and sparse real-time trajectory data. Given a path and a departure time we estimate the travel time taking into account the historical information, the real-time trajectory data and the correlations among different road segments. We detect similar road segments using historical trajectories, and use a latent representation to model the similarities. Our experimental evaluation demonstrates the effectiveness of our approach.
