摘要

提出了一种模型预测控制(MPC)方法来优化协调高速公路交通的可变限速。特别地，我们考虑离散值可变速度限制。此外，我们还施加了一个安全约束，以防止驾驶员遇到速度限制下降大于10公里/小时的情况。控制目标是最小化车辆在网络中花费的总时间。这种方法产生了动态速度限制，从而减少甚至消除了冲击波。

Optimal coordination of variable speed limits to suppress shock waves

We present a model predictive control (MPC) approach to optimally coordinate variable speed limits for free-way traffic. In particular, we consider discrete-valued variable speed limits. Moreover, we also impose a safety constraint that prevents drivers from encountering speed limit drops larger than, say, 10 km/h. The control objective is to minimize the total time that vehicles spend in the network. This approach results in dynamic speed limits that reduce or even eliminate shock waves.
