信息技术的快速发展为我们理解交通现象提供了新的视角，并有助于缓解交通问题。信息技术在交通和运输分析中的一个关键应用是使用全球定位系统（GPS）识别移动物体的位置。预计可以利用这些数据进行详细的交通分析。在这篇文章中，我们首先总结了探测数据在输运分析中的各种应用。GPS数据只是一系列位置，需要进一步的数据转换，如地图匹配，数据简化，处理和报告，以有效地使用它们。然后，我们讨论了公交车探测数据的应用，以评估行程时间的变化和服务水平（LOS）的道路。提出了一种利用公交车探测器数据从行程时间稳定性和可靠性的角度对路网进行评价的方法。任意路径的旅行时间分布估计统计总结直接观察到的多个旅行时间分布。基于公交车调查覆盖的任意路径的行程时间分布估计方法的发展，本研究提出了一种基于行程时间可靠性概念的道路网络服务水平评估方法。
The rapid progress of information technology (IT) may provide us with new insights into understanding traffic phenomena, and could help mitigate traffic problems. One of the key applications of IT to traffic and transport analysis is the identification of the location of moving objects using the Global Positioning System (GPS). It is expected that detailed traffic analysis could be carried out using these data. In this article, we first summarize the various applications of probe data in transport analysis. GPS data are merely a sequence of locations, and further data transformation such as map-matching, data-reduction, processing, and reporting is needed to use them effectively. We then discuss the application of bus probe data to evaluating travel time variability and the level of service (LOS) of roads. A methodology for evaluating the road network from the viewpoint of travel time stability and reliability using bus probe data is proposed. Travel time distributions of arbitrary routes are estimated by statistically summing up directly observed multiple travel time distributions. Based on the development of methodologies to estimate travel time distributions of arbitrary routes covered by the bus probe survey, this study proposes an approach to evaluate the LOS of road networks based on the concept of travel time reliability.
