基于可变信息标志（VMS）的预期出行者信息系统旨在通过预测交通状况来设计与驾驶员路径选择行为相一致的控制策略，引导驾驶员通过高速公路-干线网络，改善系统性能，从而缓解经常性和非经常性拥堵。为了有效地提供与驾驶员的途中分流行为和控制器的目标相一致的预期旅客信息，本研究探讨了（i）使用聚合级数据的时变驾驶员的途中分流模型的参数的自动校准，以及（ii）主动路线引导方案，该方案将网络状态投射到不久的将来，并确定时空协调的预期旅客信息。该系统在真实的世界网络上进行了测试。实施结果表明，该模型提供的预期出行者信息更加一致，因此更容易被驾驶员接受。研究结果还表明，协调的VMS为基础的预期旅客信息有效地提供了指导司机，因为它占交通状况的空间和时间的变化，并鼓励更好地利用道路容量，从而导致更好的系统性能在同一时期的操作。
Anticipatory traveller information system based on variable message sign (VMS) aims to relieve recurrent and non-recurrent congestion by using predicted traffic conditions to design control strategies consistent with drivers' route choice behaviour to guide drivers through the freeway-arterial networks and improve system performance. To provide anticipatory traveller information consistent with drivers' en-route diversion behaviour and controller's objectives effectively, this study examines (i) automated calibration of the parameters of a time-variant drivers' en-route diversion model using aggregate-level data, and (ii) an active route guidance scheme, which projects the network states into the near future and determines spatiotemporal coordinated anticipatory traveller information. The proposed system is tested on real world networks. The implementation results demonstrate that the anticipatory traveller information provided by the proposed model is more consistent, and therefore easier to be accepted by drivers. The findings also reveal that the coordinated VMS-based anticipatory traveller information effectively provides guidance to drivers because it accounts for the spatial and temporal changes in traffic conditions, and encourages better use of roadway capacity, thereby resulting in better system performance over the same period of operations.
