ABSTRACT
Traditional traffic signal control methods have not played an effective role in alleviating traffic congestion. In order to make better signal control decisions, this paper combines deep recurrent Q network (DRQN) to carry out in-depth research on the optimization of signal controls. The core idea of this approach is to set up a deep neural network to learn the Q-function of reinforcement learning from state inputs and performance output. Specific state, action and reward functions were defined in reinforcement learning, a long short-term memory (LSTM) network was used to fit the state, then the appropriate signal control strategy was proposed. SUMO software was used for simulation experiments to create a single intersection traffic signal control.
