摘要:

本文提出了一种 freeway 交通流的混合系统案例研究。我们描述了两种通用网络类别,用于建模具有合并匝道的 freeway 上的流量。每个匝道的交通流准入率通过控制输入进行计量。这两种网络类别易于扩展以适应任意状态维度。该模型是离散时间的,并具有分段仿射动力学。此外,我们提出了几种特别适用于交通流管理的控制目标。所提出的模型具有灵活性和可扩展性,并为评估混合系统开发的工具和技术提供了基准。

英文摘要:

In this note, we propose a case study of freeway traffic flow modeled as a hybrid system. We describe two general classes of networks that model flow along a freeway with merging onramps. The admission rate of traffic flow from each onramp is metered via a control input. Both classes of networks are easily scaled to accommodate arbitrary state dimension. The model is discrete-time and possesses piecewise-affine dynamics. Moreover, we present several control objectives that are especially relevant for traffic flow management. The proposed model is flexible and extensible and offers a benchmark for evaluating tools and techniques developed for hybrid systems.
