Research On The Capacity Of Main Distribution Equipment Of Railway Station

The rapid development of railway line is not only reflected in the aspects of increasing train operation ability, also reflected in some aspects with the passenger to enhance the capability of passenger distribution. Research to improve the existing distributed to improve our ability to passenger railway transportation quality and service is necessary. This paper focuses on how to improve the ability of railway main distribution equipment and using the method of mathematical modeling and combining with actual example of main distribution equipment ability enhancement method for quantitative description.The paper firstly analyzed the current research at home and abroad. Then summarize current situation of existing railway station, including introduction. The paper has analyzed the status and defects of the main distribution device, such as the station square, the waiting hall, the passenger channel, etc. Distribution equipment capability, the passenger traffic flow characteristics, passengers walk characteristics, what are influenced each other. So it will present at the summary analysis of the railway station current situations. In the study how to improve the existing railway station main distribution equipment capability, this paper studies the station square, the waiting hall, the passenger channel influence factors of ability, put forward the corresponding improving methods. The station square can adopt the method of reconstruction.. In this method, based on the analysis of passenger needs to change, the demand of each element composed the station square measure, and through the scale of transfer mode passenger station square, analyzes and calculates the scale of elements. For example, in Chengdu Station with the characteristics of the parking lot, and suggested the spatial change to save land and project investment.The waiting hall adopts reconstruction and passenger flow optimization method. According to study the peak of the waiting hall to create a mathematical model, and contrast analysis of lateral line waiting organization model with elevated overcrossing waiting organization model. Passenger flow optimization based on passenger in the waiting hall for the shortest, walking distance of approximate number of suggestions from the entrance near the train of the arrangement of the ticket and proper identification to reduce passengers to walk in the hall. Passenger walk channel by reconstruction and expansion, combining reconstruction and expansion optimization methods. For the reconstruction of the channel, the paper presented the matching relations of the channel capacity and train arrive passage through the peak hour traffic. If this time arrived is more than the best channel capacity, channel need expansion. For the research of the passage scale and the amount, the thesis gathers the traveller of passage to is over a view to is divided into a passage infield view namely the passage control gathers to spread with the passage both ends import and export scene namely the bottleneck control gathers to spread and gathers to spread the relation between number and passage scale inside the passage by research, two kinds of to these gather to is over a view of gathering and spreading calculate way research, travellers' numbers of the judgment passage infield view, the traveller who then expresses inside the passage counts the amount of traveller smaller than passage and explain the scale of passage has already been not enough to complete an existing traveller to gather to spread and combine to change an extension method to the passage of the scale carry on an extension. The thesis finally combines all north the station mainly gather to spread an equipments ability exaltation to put forward a homologous method to the station, and measure to calculate as to it's set up, the scale carry on quantity to turn a description. In order to achieve coordinated ability of points and lines, the paper studied the railway station main distribution equipment, and put forward improving station plaza, waiting hall, passengers stood in the methed, has certain theoretical significance and application value.
