HIGHWAY-LEVEL VEHICLE CONTROL FOR AHS

Current research on advanced vehicle control systems (AVCS) emphasizes the regulation of individual vehicles from a vehicle-level point of view. To improve the roadway operational efficiency, however, it is necessary to coordinate the operations of the vehicles on the highway. In this paper, a highway-level control algorithm is proposed which optimizes the traffic flow from a system-level viewpoint. The highway is divided into cells. The density and average speed of vehicles in these cells are assumed to be measured in real-time. Desired vehicle acceleration and lane change commands are assumed to be transmitted through communication devices to the vehicles, which optimize the traffic flow over the whole highway section. The system-wide traffic is optimized by using the downstream traffic status as the 'preview' information for upstream traffic regulation. Numerical simulations were performed to validate the effectiveness of the proposed control algorithms.
