| With the rapid development of urban traffic,traffic congestion has become an inevitable traffic problem.while as an important part of urban traffic,the research on organization and management of pedestrian traffic has been paid more and more attention.While bringing security concerns,pedestrian traffic congestion also increased pedestrian travel delays,thereby affecting the operation efficiency of the city traffic.Based on the traffic characteristics of pedestrians in pedestrian channel,this paper establishes a pedestrian cellular automaton model,and applies the research on the pedestrian crossing of no signal control.First of all,this paper selects a typical entrance channel of the train station to survey,and accesses to detailed data including traffic status,traffic demand and characteristics of pedestrian flow.The characteristics of pedestrian characteristics are analyzed from the perspective of macro and micro.This paper proposes the influencing factors of pedestrian traffic characteristics in the channel and analyses the change of pedestrian status and traffic characteristics under different factors.Secondly,a model of pedestrian cellular automata simulation model was established considering the parameters of the channel and the characteristics of the pedestrian behavior.This paper summarizes the distance parameters,the vacancy parameters,conformity parameters and forward parameters,developing the evolution rules of the model using sequential update.Then this paper analysis the pedestrian traffic characteristics under different pedestrian arrival rate,and reveals the macroscopic and microscopic behavior characteristics of pedestrian in the channel.Finally,the model of cellular automata on pedestrian crossing of no signal control was established,considering the collision between the pedestrian and the motor workshop.Based on the model of the pedestrian,two pedestrian parameters are added including safety parameters and horizontal parameters,which makes the pedestrian model more suitable for the simulation environment.This model takes the pedestrian arrival rate as the independent variable,takes the average speed,density of vehicle and the average speed,density of pedestrian as the dependent variable,and analysis the traffic characteristics of vehicles and pedestrians on the pedestrian crossing of no signal control.The model has high research value on optimizing pedestrian traffic organization and reasonable allocation of the channel space resources,which can provide theoretical basis and improvement plan for the planning and design of pedestrian channel in the future. |
