Comparison of Feedback Control Schemes for Traffic Jam Based on Lattice Hydrodynamic Traffic Model
摘要
Abstract
Objective]Looking for the feasible solution to suppress traffic jams and control traffic emission.[Methods]The mean-field feedback control scheme on lattice hydrodynamic traffic e-quation is constructed by considering an average effect exerting on traffic flow on road.The nonlinear feedback control scheme is proposed via considering the sine variation of the flow difference value on the nearest-neighbor unit on grid as control term.The stability condition is obtained by stability analysis.By simulation analysis,four control effects for the mean-field feedback control scheme,the nonlinear feedback control scheme,Ge’s feedback control scheme and Redhu and Gupta’s delay feedback control model are compared.[Results]All of studies in-dicated that the four schemes can suppress traffic j ams effectively.From results of numerical simulations,the mean-field feedback control scheme,nonlinear feedback control scheme and Ge’s feedback control scheme have the better control effects.In the practical application,non-linear feedback control scheme,Ge ’s feedback control scheme and Redhu and Gupta’s delay feedback control model are easily realized.[Con-clusion]The nonlinear sine feedback control scheme and Ge’s feedback control scheme reveal better control effects and easier to realize sup-pressing traffic j ams.关键词
