Based On Multi-value Electric Bicycle-Bicycle Traffic Flow Characteristics Of Cellular Automata Simulation Study

In recent years,with the development of new energy,the ownership of electric bicycles is increasing sharply in the plains,which constitute the non-motor vehicle road traffic flow model with the bike together.And,the study of this new type of mixed traffic flow is less.But,in the northern plains city,electric bicycles and bicycle traffic on the motorways phenomenon is very common.Therefore,it will be a very meaningful ting to study the characteristics of mixed non motorized traffic of urban roads composed by bicycle and electric bicycle.The main content of this paper includes the following sections:1)For existing based on cellular automata model of mixed traffic flow in the non-motor vehicle lanes for re-election,build open boundary condition,based on the theory of multivalued cellular automata model of mixed traffic flow composed of the electric bicycle and bike.And in view of the existing non-motor vehicle lanes(width is 4 meters)simulation.Through simulation data,the paper analyzes the non-motorized road traffic and the change of the ratio of the electric bicycle on the influence of mixed traffic flow.2)Put security in existing non-motorized road isolation facilities,electric bicycles and bicycle for diversion,and boundary conditions for the development of this paper has built,based on value theory of mixed traffic flow cellular automata model was improved,re-established multivalued cellular automata model,the improved non-motor vehicles on electric bikes and bicycle traffic flow simulation.Through the simulated data,the paper analyzes the non-motorized road traffic and the change of the ratio of the electric bicycle on the division of non-motor vehicles on the influence of traffic flow.3)Through this paper established two kinds of model simulation results,analysis of non-motor vehicle and electric bicycles traffic proportion of non-motor vehicle lanes from the change of before and after the effects of the traffic flow in road.Data show that in the existing non-motor vehicle lane width(4 meters),when the flow rate is in excess of 2500 / hour,on a non-motor vehicle road simulation security isolation facilities for non-motor vehicle traffic safety,driving fast.4)According to the established model,think about the future after further widen the non-motor vehicle lanes(considering widened to 5 m)in this article,the effect of a non-motor vehicle road safe isolation facilities.Results show that when the non-motor vehicle lane width of 5 meters,due to the width of the non-motor vehicle lanes is enough big,at this point,placed on a non-motor vehicle road safety isolation facilities effect is not obvious.
