公共交通是智能互联社区的重要组成部分。因此,公民期望并需要有关交通资产实时到达/出发的准确信息。随着交通机构实现实时传感器的大规模集成并支持后端数据驱动的决策支持系统,动态数据驱动的应用系统 (DDDAS) 范式成为一种有前途的方法,通过提供在线模型学习和多时间尺度分析作为 DDDAS 反馈循环中使用的决策支持系统的一部分,使系统变得更加智能。在本文中,我们描述了纳什维尔使用的系统,并说明了我们团队开发的分析方法。这些方法使用历史数据和实时流数据来进行在线公交车到达预测。历史数据用于构建分类器,使我们能够创建预期的性能模型并识别异常。这些分类器可用于向地铁交通当局提供时刻表调整反馈。我们还展示了如何将这些分析服务打包成模块化、分布式和弹性的微服务,这些微服务可以部署在云后端以及边缘计算资源上。
Public transit is a critical component of a smart and connected community. As such, citizens expect and require accurate information about real-time arrival/departures of transportation assets. As transit agencies enable large-scale integration of real-time sensors and support back-end data-driven decision support systems, the dynamic data-driven applications systems (DDDAS) paradigm becomes a promising approach to make the system smarter by providing online model learning and multi-time scale analytics as part of the decision support system that is used in the DDDAS feedback loop. In this paper, we describe a system in use in Nashville and illustrate the analytic methods developed by our team. These methods use both historical as well as real-time streaming data for online bus arrival prediction. The historical data is used to build classifiers that enable us to create expected performance models as well as identify anomalies. These classifiers can be used to provide schedule adjustment feedback to the metro transit authority. We also show how these analytics services can be packaged into modular, distributed and resilient micro-services that can be deployed on both cloud back ends as well as edge computing resources.
