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.

交通信息时代的布雷斯悖论

Braess 悖论描述了一种违反直觉的情况，即在道路网络中增加新道路可能会导致所有网络用户的出行时间更长。最近，我们可以证明导致悖论的用户优化存在于微观传输模型的网络中。我们导出了两种路由选择策略的相图，这些策略由所有网络用户进行外部调整和应用。在这里，我们解决了如果基于两种交通信息做出智能路线选择决策，这些用户优化是否仍然实现的问题。我们发现，如果驾驶员 1) 根据自己过去的经验做出明智的决定，或者 2) 使用类似于现代导航应用程序提供的交通信息，悖论仍然可能发生。
