Description
Technical Field
The invention relates to the field of transportation, in particular to a passenger flow analysis method for a bus rapid transit special platform and related equipment.
Background
The Bus Rapid Transit (BRT) is a novel public passenger transport system operating in a city Bus lane, and has the characteristics of high capacity, convenience in taking and high speed in operation. The bus rapid transit special station (called BRT platform for short) is one of the core components of the urban bus rapid transit system and has two forms of a road central island type and a road side type. The BRT platform is used for the stop of rapid bus line operation vehicles and the getting-on and getting-off of bus passengers, and also plays a role of a passenger transfer pivot point. The larger the transfer passenger flow of the BRT platform is, the higher the proportion of the transfer passenger flow to the passenger flow of the BRT platform is, the more obvious the connection effect exerted by the BRT platform is, and the higher the effect exerted is.
At present, most urban buses adopt boarding payment (IC card swiping, mobile phone two-dimensional code scanning payment and the like) and get off without payment; the BRT stations are designed to pay on-site (BRT stations) and pay off-site (BRT stations). Due to the lack of the data of getting off the bus, the passenger flow analysis can only analyze the passenger flow on each BRT platform, but cannot effectively analyze the passenger transfer travel behavior to obtain the transfer passenger flow and the transfer traffic volume survey (OD), so that the problems of the proportion of the transfer passenger flow of the rapid transit system and the evaluation of the service efficiency of the BRT platform are solved.
At present, two manual passenger flow investigation methods, namely field manual passenger flow OD investigation recording and video passenger flow data dike investigation, are mainly adopted for BRT transfer passenger flow volume analysis in each city, but for adopting the field manual passenger flow OD investigation recording, the problems of small investigation sample proportion, low precision, high cost, poor timeliness, long investigation period, difficult data processing in the later period and the like exist, and the dynamic change characteristics of the travel requirements of passengers cannot be reflected; for bus passenger flow video counting investigation, because the current video passenger flow counting can not realize passenger face identification and can not obtain passenger identity characteristics, the travel track of the passenger can not be tracked and analyzed, and the transfer behavior and transfer OD data in the passenger station can not be analyzed temporarily.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
The following describes a passenger flow analysis method for a bus rapid transit dedicated platform from the perspective of a passenger flow analysis device for a bus rapid transit dedicated platform, which may be a server or a service unit in a server.

101. and acquiring a positioning track of the vehicle in the target range within a preset time length and payment data of a passenger corresponding to the vehicle within the preset time length.
In this embodiment, the passenger flow analysis device at the bus rapid transit dedicated platform can obtain a positioning track of a vehicle in a target range within a preset time and payment data of a passenger corresponding to the vehicle within the preset time, wherein the vehicle comprises the bus rapid transit vehicle and a conventional bus which is connected with the bus rapid transit dedicated platform of the bus rapid transit vehicle; the payment data comprises passenger boarding payment data and passenger BRT arrival payment data, wherein the passenger boarding payment data comprises a user number, a line number, payment time and a payment type; passenger BRT inbound payment data includes: user number, station name (number), station order, payment time, and payment type; the positioning track comprises information such as a vehicle number (license plate number), a line number (line name), longitude and latitude coordinates, a time value, a direction angle, a speed value and the like. It is understood that the target range may be a city, such as wuhan, or a certain region in the city, such as wuhan marchan, and the preset time period may be 7 days, or 15 days or 1 month, and is not limited.
102. And acquiring basic information of the rapid public transport system line network in the target range.
In this embodiment, the passenger flow analysis device at the bus rapid transit dedicated station can obtain basic information of the bus rapid transit system line network within a target range, where the basic information includes all bus rapid transit passenger flow corridors, all bus rapid transit access line bidirectional station names, station coordinates, and station order information within the target range; that is to say, the passenger flow analysis device for the bus rapid transit special platform can extract a station collection and a collection of line stations according to the line-station correspondence, so as to form a bus rapid transit platform matrix. For example, forward stations of a bus rapid transit B1 line are sequentially named as B1-F-A1 and B1-F-A2 … … B1-F-A12, and reverse stations are station sequences B1-B-a1 and B1-B-a2 … … B1-B-a12 at one time; by analogy, forward stations of the Bn line of the bus rapid transit are named as Bn-F-N1 and Bn-F-N2 … … Bn-F-Nx in sequence, and reverse stations are named as Bn-B-N1 and Bn-B-N2 … … Bn-B-Nx in sequence once. According to the programmed mapping relation of codes of all line stations of the bus rapid transit system, for example, "B1-F-A12" and "B1-B-a 1" in a B1 main line are the same central island type BRT station, and the mapping relation of all line stations (BRT stations and conventional bus stations) and station sequence codes is sequentially established.
It should be noted that the passenger flow analysis device at the bus rapid transit dedicated station can obtain the positioning track of the vehicle within the target range and the payment data of the passenger corresponding to the vehicle within the preset time period through step 101, and can determine the basic information of the line network of the bus rapid transit system within the target range through step 102, however, there is no sequential execution order limitation between these two steps, and step 101 may be executed first, or step 102 may be executed first, or executed simultaneously, and the specific implementation is not limited.
Next, the passenger flow type and the combination type of the BRT station express and transfer passenger flow travel station are described with reference to fig. 2, and fig. 2 is a schematic view of the passenger flow express and transfer paths of the bus rapid transit system according to the embodiment of the present invention, and the passenger flow type is first described.
Firstly, the passenger flow type comprises a direct passenger flow type and a transfer passenger flow type:
1. a type of passenger flow;
directly reaching passenger flow:
in the rapid transit system, passengers get on and off stations on the same line, the passengers can directly arrive by considering the line, and the passengers are not considered to be transferred. The direct passenger flow counted in the invention refers to the rapid public transport direct travel passenger flow with the getting-on station or the getting-off station as a BRT station, and is related to the BRT station.
Therefore, the travel behaviors which are not actually connected with the BRT station, including the direct passenger flow of the conventional bus station (approach BRT station) of both the getting-on station and the getting-off station, do not belong to the consideration range of the invention.
Secondly, passenger transfer flow:
in the bus rapid transit system, the stations for passengers to get on and off the bus are not on the same B line, and the passengers need to be transferred through the BRT stations and are regarded as transfer passenger flows. Therefore, only the travel passenger flow of the rapid transit system for transferring another line through the BRT platform (free) needs to be calculated.
BRT platform up to passenger flow category:
the method comprises the following steps of swiping a card at a BRT platform to enter a station, taking a rapid bus line to directly go out or taking a rapid bus line (main line or branch line) to directly go out of the BRT platform, and getting off and leaving passenger flow types, wherein the types are divided into two types:
swiping cards from a BRT platform to enter a station, taking B1 and B2 lines or other lines capable of taking B lines in a bidirectional way, and taking off the station as the BRT platform or the station along the B lines which are taken, having no transfer behavior and belonging to direct passenger flow;
and secondly, swiping a card to get on from other conventional bus stations which are not BRT stations, getting off and getting off at the BRT stations by taking a B line, having no transfer behavior and belonging to direct passenger flow.
(3) BRT station transfer passenger flow category:
the BRT stations are punched to get on the bus by B1, B2 or other lines which can be taken, other lines are transferred at other BRT stations (transfer stations), and transfer behaviors exist at the BRT stations, belonging to transfer passenger flow.
Swiping a card at a non-BRT (conventional bus stop) platform to take a B line for getting on the bus, getting off the bus at the BRT platform to transfer other B lines, and having transfer behavior at the BRT platform, belonging to transfer passenger flow;
and secondly, combining the BRT platform direct and transfer passenger flow traveling platforms.
With reference to fig. 2, the bus rapid transit system has two main line modes, B1 and B2.
Line B1 is set as a full-journey BRT station (no conventional bus station), passengers can only get in after payment at the BRT station, take vehicles of line B1 and select to transfer other BRT branches along the BRT station at line B1.
The line B2 is set up so that some stations are BRT stations and some stations are conventional bus stations. Passengers can get on the station after paying at the BRT station, take the vehicles on line B2 and select to transfer other BRT branches along the BRT station on line B2; and the vehicle can also pay for getting on the bus at a conventional bus stop on a line B2, and the vehicle on a line B2 can selectively transfer to other BRT branches at a BRT stop along the way.
According to two main line modes of B1/B2, the following BRT platform passenger flow related direct and transfer travel behaviors are analyzed:
(1) direct passenger flow trip platform combination type;
(ii) a BRT station (O) -BRT station (D);
the BRT platform is swiped to enter the station, and the passengers get off the vehicle at the BRT platform by lines B1 and B2 to directly arrive at the BRT platform.
A BRT station (O) -a conventional bus station (D);
the BRT station is punched to enter the station and is directly reached by a same-station route (B2 and other branches).
③ a conventional bus station (O) -BRT station (D);
and (3) swiping a card to get on the bus at a station of a non-BRT station on the line B2 or getting on the bus at a conventional station of a branch line connected with the BRT station, and getting off the bus at the BRT station connected by a fast bus line to directly get on the bus.
(2) The combination types of the boarding platform, the transfer platform and the disembarking platform of the transfer passenger flow are as follows:
BRT station (O) -BRT station (T) -conventional bus station (D);
and (3) swiping a card at the BRT station to get in the station and taking the B line, transferring a transfer branch line at the connected BRT station, and getting off the bus at the conventional bus station.
BRT station (O) -BRT station (T) -BRT station (D);
the BRT platform is blocked by a card to enter the station and takes the B line, the B line is connected at the transfer station of the connected BRT platform and the other BRT platform is unloaded.
A conventional bus station (O) -BRT station (T) -BRT station (D);
getting on the bus at the conventional station of the line B, taking the line B to get off the bus at the transfer BRT platform, and getting off the bus at the BRT platform by transferring other lines B.
Conventional bus station (O) -BRT station (T) -conventional bus station (D).
Getting on the bus at the conventional bus stop of the B line and taking the B line, getting off the bus at the transfer BRT platform and transferring other B lines, and getting off the bus at the conventional bus stop.
103. And determining the origin-destination of the target passenger according to the positioning track, the payment data and the basic information.

The following is a detailed description:
after obtaining the positioning track, the payment data and the basic information, the passenger flow analysis device of the bus rapid transit special station can carry out data cleaning and standardization processing on the data, then carry out passenger riding data matching on the data after the data cleaning and standardization processing, then calculate the origin-destination of the passenger, when the origin-destination is determined, the passenger travel analysis device aims at IC card data processing, and when the vehicle data exists, a BRT line judges the getting-on station of the user according to the card swiping time and the vehicle GPS data; the following explains the analysis of the BRT get-off data:
