| Abstract(in English) | Traffic congestion of vehicles is considered to be a social problem, leading to waste of transportation time. To suppress traffic congestion, various methods for controlling vehicles have been proposed. In this report, within the framework of the optimal velocity model of traffic flows, we propose a control method for suppressing traffic congestion by using the information of local vehicle density. In the original optimal velocity model, the velocity of each vehicle is determined by the optimal velocity function, which specifies the target velocity as a function of the distance between the vehicle and its preceding vehicle just ahead of it. In our proposed method, the parameter of the optimal velocity function is moreover updated depending on the local density of the vehicles. By numerical simulations, we analyze how the traffic state depends on the number of the vehicles used to estimate the local vehicle density and on the global vehicle density. It is found that the proposed method can lead to formation of vehicle groups, thereby suppressing congestion and increasing total traffic flow. |
