Distribution Routing Choice Of Beijing Based On Congestion Probability

It is the serious traffic congestion problem that greatly reduces the distribution efficiency.In order to improve the quality of distribution services and meet the requirement,the distribution enterprises have to invest in vehicles.That must lead to more serious traffic congestion.How to avoid traffic congestion or how to choose the appropriate path faced with the uncertain congestion situation is the huge challenge for the every distribution enterprises.In this context,this paper carries on the following simulation research.Beijing is the object in this paper.First,this paper analyzes the Beijing's road network and the layout of logistics center in Beijing.Congestion probability is calculated by observing the traffic situation in Beijing for a long time and is divided into two types,namely congestion probability in peak hours and off-peak hours.Then this paper analyzes the distribution needs in Beijing,sets up the operation flow of Beijing urban distribution model based on congestion probabilities and establishes the Agent simulation model(including Main Agent,Client needs Agent and Transport Agent)in Anylogic simulation platform model.Next,combined with the actual traffic conditions in Beijing,the simulation is opeprobabilityd.Finally,the simulation results are mainly analyzed in three aspects:distribution route,distribution distance and distribution time.According to the simulation results,some key road can be used to provide reasonable suggestions for the choice of distribution route.The conclusions of this paper are as follows.On the one hand,distribution activities have influence on the traffic situation after considering the congestion probability.Under the peak hours,the traffic load of second ring and tricyclic ring is lower than that of fifth ring and sixth ring.Under the off-peak hours,the traffic load of east fifth ring,south tricyclic ring,east tricyclic ring and west tricyclic ring is higher than that of other rings.On the other hand,congestion probability has more significantly influence on choosing distribution path.
