Example 4.3 (Multi-intersection Traffic Signal Control Problem).对于具有多个交叉路口的网络,智能体被定义为环境中第 NN 个交叉口的信号控制器。用RL控制的交通信号智能体的目标是学习每个智能体的最优策略以及优化整个环境的交通状况。在每一个时刻 tt ,每个智能体 ii 观察环境的一部分作为观察值 otioit 。智能...
Multi-Agent Deep Reinforcement Learning for Large-scale Traffic Signal Control 这篇文章相对引用量多了点,主要还是采用Multi-agent A2C的方案,对比的方案主要是Independent A2C。 在多智能体中,一般定义一个图,如果两个信控路口之间存在边相连,就定义两个信控路口相连。作者说Multi-agent A2C主要有如下两点改进: 使...
