Research On Cooperative Optimization Of Passenger Flow Line And Waiting Room For Large Railway Station

With the demand of people's travle continues growwing,the passenger taskof railway also getting more and more difficult.Waiting Hall is passenger placeof the largest number of passengers gathered and the longest residence time of the passenger.The improvement and optimization of its operational processes are becoming more and more attention by relevant experts.The optimization of the operational organization of the waiting hall of the passenger terminal plays a vital role in improving the efficiency of the operation and maintaining the orderof the station.This paper summarizes the various transportation of the relevant optimization,and anlayses the research status and developing prospect of the various transportation of the relevant optimization,simultaneously,then based on the existing research results,objectively points out the deficiencies and the some questions in thefuture research.By combining the existing research and a series of influencing factors in the process of the operation of the passenger terminal,this paper divides the job optimization problem of the waiting hall of the whole passenger station into two parts: the passenger streamline optimization and the optimizationof the waiting room allocation,The main research works of this paper are as follows:(1)Based on the analysis of the relevant factors of passenger streamlines,the objectives of passenger streamline optimization are discussed.Because the actual length of the streamline as a measure of the merits of the streamlineevaluation indicators in existing research,However,in fact,it is obviously different between the people with doing work for walking overpass bridge and underpass bridged and the people with doing work for walking level road,Therefore,this paper will be convert the length of the streamline of walking overpass bridge and underpass bridge into level road.Finally,build up a mathematical model based on the length of the streamline.(2)For the study of the using of the waiting room,this paper discusses the objective function of the existing research,discovered the most of the existing research is the balance of the day and night of the waiting room,However,in fact,the balance of the day and night does not represent the equilibrium ofeach period.Therefore,in order to the authenticity and practicability of the optimization results,this paper uses the time block to divide the day and night into several periods of different lengths and discontinuities.Through the dynamicplanning method,making the using of the balance of the waiting room as the target to the waiting room staged optimization.At the same time,in order to make describe the operation process more clearly,dividing each waiting room into a number of waiting areas,thereby,using waiting areas as the basic unit to optimization,then bulid up the objective function.(3)In order to ensure the completeness and comprehensiveness of the operation of the waiting hall of the passenger terminal,combined the passenger streamline optimization and the optimization of the utilization of the waiting zone,then research on cooperative optimization of passenger flow line and waiting room in large railway passenger station.At the same time,in order to solve this double goal optimization problem more effectively,this paper introduces the prospect theory,selecting the optimal scheme as the final optimization result by evaluating the prospect of different schemes,Aiming at the optimization objective function,this paper chooses a reasonable algorithm,and based on the relevant data of Lanzhou station,verified the effectiveness of the model and algorithm,and explained the feasibility of this paper At the end of the paper,the shortcomings of the research work and the process are expound,and the outlooks of relevent research are described.
