%X On the basis of the traffic density control design by using the nonlinear integrator-Backstepping method, thismpaper proposes an improved method for designing the traffic flow-speed control by selecting the traffic flow-speed as the controlled variable and applying the Backstepping method to design the controller for an automated highway system. The controller guarantees the traffic flow-speed at each section to be exponentially convergent to the desired speed. Comparing with the prior methods, this controller is superior in algorithm-efficiency, being free from matrix inversion, and automatically satisfying the controllability condition. Simulations show that this controller effectively reduces the congestion and helps to achieve a smooth traffic flow on a congested highway.
