Abstract: In an automated freeway system environment, computers replace artificial driving and control vehicles accompany movement, which can greatly reduce randomness. In this paper, we propose a traffic flow speed controller with lower complexity which can send speed commands to regulate the speeds of vehicles in each section of a freeway. On the basis of the theory of nonlinear integrator backstepping, the controller can guarantee exponential convergence of the traffic flow speed at each section to the desired speed. Compared with former method, the establishment of this controller need not solve inverse matrix, and therefore, reduces algorithm¡¯s complexity, improves the algorithm efficiency and automatically satisfies the controllability condition. Simulations show that this controller can effectively reduce congestion and helps to achieve a smooth traffic flow on a congested freeway.
