Simulation Of Pedestrian Flow In No Signal Control Crosswalk Between Urban Road Section

With the rapid development of social economy, the road traffic is countering more and more complex impacting events. Great amount of population is China’s basic national issue,which means that the conflicts between pedestrians and vehicles are inevitable with vehicle amount increasing in today. Has been all kinds of transportation terminal way on foot, the pedestrian is the vulnerable groups in the traffic accident. So, it is necessary to improve traffic safety by studying simulation in no signal control crosswalk between urban road section in the way to improve the traffic facilities.This thesis is based on cellular automata and pedestrians parameter model, through actual observation, analysis of pedestrians walking characteristics, establish the simulation model of no signal control crosswalk in urban road section. The specific contents of this paper as follow:The first chapter mainly illustrates the thesis research background and significance based on the analysis of domestic and foreign research scholars who focused on no signal control crosswalk in urban road section based on the present situation of the research, and defines the research ideas and the main technical routes of this paper.The second chapter introduces the cellular automata definition, composition, characteristics, and the direction of the pedestrian parameter model, the Direction-parameter, the Empty-parameter, the Forward-parameter and the Category-parameter space. Based on the basic theory of cellular automata and the pedestrian parameter model, establish suitable for the simulation model of this paper.The third chapter analysis walking rule on one-way pedestrian flow and two-way pedestrian flow. Establish the pedestrians parameter simulation model based on the cellular automata model. Through the simulation, analysis relationships pedestrian density and the rate of pedestrian flows walking through the street of one-way pedestrian flow and two-way pedestrian flow.The fourth chapter analysis characteristic of pedestrian flow and vehicle flow when the pedestrian through the continuous traffic flow. Establish the vehicle- pedestrian flow simulation model based on cellular automata and pedestrians parameter model. Analysis of the influence of different number of lanes and rate of pedestrian flows through the street, and the influence of one-way lanes and two-way lanes and rate of pedestrian flows through the street.The fifth chapter makes a general summary of the this paper, the model’s own defect was analyzed, and put forward some further ways to solve the coming problems.
