The invention discloses a ramp control method for solving the congestion problem of a bottleneck section of an expressway. The method comprises the following steps of (1) determining the bottleneck section of the expressway, and arranging a coil detector, (2) setting signal lamps at the entrance and exit of the ramp, and calculating a Q value through receiving a state set and an action set by deep reinforcement learning, (3) constructing a simulation road network by applying an SUMO simulation platform, (4) determining three indexes of deep reinforcement learning, namely a state set, an action set and a return function, and formulating a control strategy, (5) enabling the intelligent agent to execute the signal lamp, and (6) calling a TraCI interface of the SUMO simulation platform by utilizing a Python language to start simulation, then acquiring data in simulation in real time by utilizing statements, extracting useful information, calculating a control strategy, obtaining a corresponding control strategy result, and then calling the TraCI interface to set the color of a signal lamp in simulation so as to realize the application of the control strategy.
