论文摘要
胸罩悖论描述了违反直觉的情况,即在道路网络中增加新的道路可以为所有网络用户带来更高的旅行时间。最近,我们可以证明导致悖论的用户在微观传输模型网络中存在。我们为两种路由选择策略提供了相图,这些策略均由所有网络用户进行外部调整和应用。在这里,我们解决了一个问题,如果根据两种流量信息做出智能路线选择决定,是否仍然可以实现这些用户最佳选择。我们发现,如果驾驶员1)根据自己的过去经验做出明智的决定,或者2)使用与现代导航应用程序提供的交通信息。这表明现代交通信息系统无法解决Braess的悖论。
The Braess paradox describes the counterintuitive situation that the addition of new roads to road networks can lead to higher travel times for all network users. Recently we could show that user optima leading to the paradox exist in networks of microscopic transport models. We derived phase diagrams for two kinds of route choice strategies that were externally tuned and applied by all network users. Here we address the question whether these user optima are still realized if intelligent route choice decisions are made based upon two kinds of traffic information. We find that the paradox still can occur if the drivers 1) make informed decisions based on their own past experiences or 2) use traffic information similar to that provided by modern navigation apps. This indicates that modern traffic information systems are not able to resolve Braess' paradox.
