Research On The Simulation And Optimization For Traffic Cohesion Of Beijing Station

Beijing station is one of the important traffic hub in Beijing, it plays a role of linking up Multiple transportations such as railway traffic, urban rail traffic and road traffic, and it directly affects the operation efficiency of traffic network which is belongs to its area.Combining with actual study works which come from my tutor's research project" the simulation and optimization research on cohesion between railway station and the public traffic system", in this paper, I select the Beijing station as research object and study on the cohesion of whose traffic system.After researching the basis of traffic system simulation both domestic and foreign. Firstly, analyzing the profiles and traffic streamline of Beijing station Secondly, simply introducing the simulation software used in this paper—VISSIM, including its Basic principle, application scope, the vehicle-following model and the lane-changing model which are used in the simulation software; Subsequently, analyzing the necessary basic data which are parameters for the simulation model, then establishing the simulation model of Beijing station traffic system and putting up the evaluation index of traffic flow organization; Finally, analyzing the outputting simulation results by reliability analysis. After testing the reliability of the outputting results, analyzing the transfer efficiency of Beijing station traffic system, and putting up the optimization advices on bottleneck lanes or bottleneck facilities of Beijing station traffic system.
