Variable Speed Limit Plate Signs Based on Depth Recognition Control

Predictive control (PC) is an advanced control algorithm, which is widely used in industrial process control. Among them, model-based predictive control (MPC) is an important branch of predictive control. Its basic principle is to use the system model to predict future behavior and determine the current control action by optimizing the objective function. Based on the algorithm combined with three different sections using deep learning technology to identify vehicles and output the optimal speed limit, to achieve the effect of traffic flow optimization.
