In the light of Konishi et al.’s car-following model, considering safe headway effect of the two preceding cars on the following one, a novel feedback control scheme in the discrete car-following model is proposed. The stability condition is analysed under which the traffic system is steady running. When our scheme is applied to the discrete car-following model, the stability region could be enlarged effectively. Through simulation, we can obtain the result that our model exhibits a better effect that suppresses traffic jams compared with previous congestion control methods, and simulation outcomes are consistent with the theoretical derivation results. Because of considering information factor of multi-preceding vehicles, our controller is useful for investigation of intelligent transportation systems.
