Problems solved by technology

[0002] The station platform is one of the most important facilities in the urban rail transit system. It is of great significance for the operation and management of the station to grasp the changing law of passengers gathering and dissipating on the platform, and to analyze and predict the peak of the number of people gathered on the platform and the time of occurrence. There are several calculation methods for the number of people gathered on the platform of urban rail transit stations, but the existing methods do not consider the impact of stranded passengers on the number of people gathered, and it is difficult to calculate the number of people gathered on the platform of urban rail transit stations under the condition of large passenger flow

Embodiment 1

[0113] refer to figure 1 , a kind of calculation method for the number of people gathered on the urban rail transit station platform considering stranded passengers according to the present invention is as follows:

[0114] 1. Establish the passenger retention volume P at the facilities of the platform when the passenger flow into the platform is one-way rz (t) and the speed of passengers entering the platform v j (t) Calculation method

[0115] refer to figure 2 , all passengers who arrive at the platform facilities choose to take the train in the same direction, and the arrival rate of passengers is a function of time t, denoted as v sj (t), when v sj (t) greater than the maximum traffic capacity v of entering the platform facilities jmax When , the passengers entering the platform facilities are stranded, and the stranded amount P rz (t) Calculated by:

[0116] (1) Calculate the stagnation / dissipation interval

[0117] Respectively order v sj (t)≥v jmax and v sj...

Embodiment

[0212] Method application description: The above steps 1, 2, 3, and 4 represent the process of establishing a calculation method for the number of people gathered on the platform of an urban rail transit station considering stranded passengers. , the result can be calculated. Taking the calculation of the number of people gathered on the middle side platform with a calculation time of 1800 seconds as an example, the specific process of the actual application is as follows:

[0213] 1. Collect or predict platform passenger flow information and train information

[0214] (1)v sj (t) The speed of passengers arriving at the access platform facility v sj (t)=17.61t+600, t∈[0,1800], unit: person / hour;

[0215] (2) The maximum traffic capacity of entering the platform facilities v jmax = 2.5 persons / second;

[0216] (3) The maximum traffic capacity v of the facilities leaving the platform cmax = 3.75 people / second;

[0217] (4) train capacity C=1312 people;

[0218] (5) The f...

Abstract

The invention relates to a method for calculating gathered passenger numbers of platforms of urban rail transit stations by considering stranded passengers. The method comprises the following steps of establishing a calculation method for a quantity Prz(t) of stranded passengers entering a platform facility and a speed vj(t) of passengers entering the platform when passenger flow entering the platform is unidirectional; establishing a calculation method for a quantity P+rz(t) of stranded passengers entering the platform facility and a speed v+j(t) of passengers entering the platform in an up direction, and a quantity P-rz(t) of stranded passengers and a speed v-j(t) of passengers entering the platform in a down direction when the passenger flow entering the platform is bidirectional; forming passenger flow information by the quantity of the stranded passengers and the speed of the passengers entering the platform; dividing platform types of the urban rail transit stations according to physical structures of the platforms of the stations and position characteristics of the stations in routes; establishing a calculation method for the gathered passenger numbers P(t) of various platforms in combination with the passenger flow information and train running information; and judging passenger flow compositions and types of the platforms, and calculating the gathered passenger numbers of the platforms.
