新路由系统实时预判路径影响，缓解交通拥堵
Three Pillars Towards Next-Generation Routing System
- 将导航结果视为未来交通流根源，动态建模影响
- 三支柱协同：交通仿真、动态路径管理、全局优化
- 适合智能交通与城市规划研究者参考
路由结果在提升运输效率的同时，可能无意中引发交通拥堵，原因在于当前路由范式中交通状况与路由系统彼此割裂。本文提出下一代路由范式，通过实时考虑路由结果对未来交通流的影响来降低拥堵。具体而言，将路由结果视作未来交通流的根源，同时作为交通状况的成因。为实现该系统，识别出三个核心组件：1）高精度交通状况仿真，建立交通流与交通状况间的映射关系；2）未来路径管理，支持高效仿真与动态路径更新；3）全局路由优化，提升整体运输系统效率。初步设计与实验结果将被展示，并讨论相关挑战与研究方向。
原文摘要 · Abstract (English)
The routing results are playing an increasingly important role in transportation efficiency, but they could generate traffic congestion unintentionally. This is because the traffic condition and routing system are disconnected components in the current routing paradigm. In this paper, we propose a next-generation routing paradigm that could reduce traffic congestion by considering the influence of the routing results in real-time. Specifically, we regard the routing results as the root cause of the future traffic flow, which at the same time is identified as the root cause of traffic conditions. To implement such a system, we identify three essential components: 1) the traffic condition simulation that establishes the relation between traffic flow and traffic condition with guaranteed accuracy; 2) the future route management that supports efficient simulation with dynamic route update; 3) the global routing optimization that improves the overall transportation system efficiency. Preliminary design and experimental results will be presented, and the corresponding challenges and research directions will also be discussed.
