Abstract

The invention discloses a method of calculating a real-time passenger flow in a paying area at a subway station. The total get-in number and the total get-out number of people passing through a gate at a station are timely collected by an automatic fare collection system; the weights of each of trains getting in and out of the station are timely collected; taking the zero clock of each day or the start time of operation of the station as an initial time (represented by T0) of calculation, initializing the number of passengers at the station at T0 as 0 and representing with P0, i.e., P0=0; and according to a preset period, calculating the number Pi of passengers in the paying area at the station at Ti. The method timely calculates the number of passengers in the paying area at the station by tracking the get-in number and the get-out number of people passing through the subway station and the number of passengers getting in and out of a train at a platform. The method is accurate and reliable, and easy to implement onsite.

Description

A kind of real-time passenger flow computational methods of subway station paid area

Technical field

The present invention relates to field of track traffic, a kind of more particularly, to real-time passenger flow computational methods of subway station paid area.

Background technology

With the fast development of urban track traffic, subway has had become as the main means of transport of citizens' activities.But, In peak period morning and evening that the volume of the flow of passengers is larger, a large amount of passengers are internal AT STATION to be assembled, crowded scene occurs now and then so that passenger Potential safety hazard increases, easily induction unexpected incidents, contingency occurs, the impact advantage such as urban track traffic is quick, convenient Give full play to.

Domestic overwhelming majority subway station adopts the side of gate counting, human eye eye estimate and subregion video monitoring at present Method carrys out passenger flow situation in acquisition station.However, above method can not obtain the passenger flow data in subway station comprehensively and exactly：Lock Machine counts and can only record total number of persons into and out of subway paid area, and can not follow the tracks of confirmation passenger of entering the station and smoothly get on the bus or in platform It is detained, also cannot count the transfer passenger flow number within station for transfer station；There is larger error in human eye eye estimate Judge, and subjective randomness is very big；The problem of video observation is that station internal area is larger, leads to Platform attendant to have numerous The monitoring work amount of weight is it is difficult to the situation that notes abnormalities in time.In addition, the emerging skill of video count has been introduced in Some Domestic city Art, but it is limited to the development of video image processing technology, limitation is had based on the dynamic passenger flow monitoring of this technology.

Content of the invention

For problems of the prior art, the invention discloses a kind of calculating of the real-time passenger flow of subway station paid area Method, the method, by following the tracks of getting on or off the bus passenger flow quantity into and out of station number and platform of subway station, calculates station in real time and pays Take the passenger flow number in area.Method real-time is high, simple, by grasping the real-time volume of the flow of passengers, Ke Yishi in the paid area of station When assessment station in passenger the degree of crowding, staff's exhibition can be reminded in time when the degree of crowding is continued above certain numerical value Open emergency measure, such as strengthen passenger flow and dredge or current limliting etc..

For reaching above-mentioned purpose, the present invention is achieved through the following technical solutions：A kind of real-time passenger flow of subway station paid area Computational methods, specifically comprise the steps of：

S1：Pass through enter the station number and the outbound number of gate by AFC system Real-time Collection station；

Described enter the station number and outbound number is aggregate-value, represent ought in a few days by the end of current time by the gate that enters the station The number that always enters the station and the total outbound number passing through outbound gate；

S2：Real-time Collection is entered the station and weight of train during outbound by every train of our station；

The described weight of train includes the weight sum of train deadweight and contained passenger；

S3：Using the time started of daily zero point or station operation as the initial time calculating, use T₀Represent, and initialize T₀In moment station, passenger flow number is 0, uses P₀Represent, i.e. P₀=0；

Determine the time interval calculating, in the moment calculating every time and this moment station, passenger flow number uses T respectively_iAnd P_iTable Show；

S4：Set up T_iThe station paid area number expression formula in moment, as follows：

In formula,

P_i-1Represent T_i-1Moment, i.e. T_iPaying intra regional passenger traffic number in station during a upper moment；

Represent T respectively_i、T_i-1Always enter the station number, accordingly at moment stationRepresent T_i-1To T_iIn period Enter the station number at station；

Represent T respectively_i、T_i-1Always enter the station number, accordingly at moment stationRepresent T_i-1To T_iPeriod Interior station outbound number；

P^down, P^upRepresent T respectively_i-1To T_iNumber of always getting off in period and always get on the bus number, accordingly, P^down-P^upRepresent T_i-1To T_iIn period, the difference of number of always getting off and number of always getting on the bus；

Enter the station and weight of train during outbound in conjunction with the every train that step S2 is gathered

Wherein：

∑(Wⁱⁿ-W^out) represent T_i-1To T_iIn period, all trains by our station, incoming train weight and outbound Weight of train difference sum；

W:Represent passenger's standard body weight；

Further, T_iThe station paid area number expression formula change in moment turns to：

Beneficial effect of the present invention：The subway station paid area real-time passenger flow computational methods of the present invention, by following the tracks of subway That stands gets on or off the bus passenger flow quantity into and out of station number and platform, can calculate current time subway station in real time and accurately Passenger flow number in paid area, and computational methods are simple and reliable, provide reliable for rail transportation operation management analyses and decision-making etc. Foundation.
