Passenger flow and survey methods
First, the characteristics and classification of passenger flow
(1) Passenger flow (people counter and passenger counter)
Passenger flow refers to the group of passengers who need to take public transportation vehicles to move their positions to achieve their destination. It can also be explained as: the passenger flow is a general term for moving passengers in a certain section on a certain section in a certain period of time with a certain means of transportation.
(2) Passenger flow (people counter and passenger counter)
Passenger traffic is a measure of the extent to which urban residents need to take public transportation vehicles in general terms. It is by the city
And the temporary population of the suburbs and the temporary population living in the city, due to production, production
Live, etc., need to travel by car. Which includes time, place, direction,
Distance, quantity and other factors. The amount of flow is called “flow”, the direction of flow is called “flow direction”, and the time of flow is called “flow time”.
Factors affecting the size of passenger traffic include: urban nature and area, population density, economic level, employment population, urban layout, travel distance, layout of public transportation network, fare, service quality, etc.
(3) Number of passenger flow indicators (people counter and passenger counter)
In order to analyze the specific distribution of passenger flow on public transportation lines, it is usually necessary to investigate the passengers of a certain section, station or a certain line.
The quantitative indicators are as follows:
1. Flow vector Passengers traveling in the same direction in unit time
The number of people.
2. Throughput The number of passengers in a single direction through a station in a unit of time.
3. Concentration The number of people in a station (segment) who need to take public transportation vehicles per unit time.
4. Evacuation The number of passengers who get off at a station (segment) within the unit time.
5. Waiting for traffic In a unit of time, a station (segment) does not take the number of passengers stranded on the station by public transport vehicles.
6. Alternate amount The total number of passengers getting on and off a station (segment) in a unit of time.
7. Passenger traffic Passenger traffic refers to the actual public transport enterprises within a certain period of time.
The number of passengers transported. The general statistics are passenger traffic for the year, season, ten, week and day.
Second, the passenger flow survey method (people counter and passenger counter face recognition instrument)
The passenger flow survey is a regular and meticulous job. According to different investigation purposes, there can be different adjustments
Check the method. Frequently used methods include surveys of passengers and passengers, and visual surveys
(Resident Passenger Flow Survey Method), Inquiring Passenger Flow Survey Method, with the promotion of IC card technology, the use of IC card data for passenger flow analysis has gradually become a new fast and effective passenger flow survey method.
Pay attention to the following two points when choosing a survey method
First, get as much accurate survey data as possible with the least amount of labor and time spent.
Second, try to get the cooperation of the respondents in the easiest way to ensure the timeliness and reliability of the required information.
The following is a survey of various possible forms of investigation.
(a) with the passenger flow and survey method (people counter and passenger counter face recognition instrument)
1. Survey of passenger flow survey (people counter and passenger counter)
The on-board passenger flow survey is a comprehensive survey of the number of passengers boarding each station at each station and the number of stations remaining at the station in each vehicle operated by the line.
It can be carried out in the city or in part or on a line. It can be organized during the entire day of business hours or during a certain business hours. This depends on the different purposes of the investigation.
This survey method is a larger survey method, which is based on the operation of all vehicles from the first shift to the end of the evening.
The accuracy of the passenger flow survey data is very important, it reflects the line in transit
The number of people getting on and off at each station and the number of passengers in the car at each time. According to the number of ordinary tickets sold per trip, the number of ordinary votes and the number of IC card swipes can be counted.
With the data obtained from the passenger flow survey, the passenger flow can be reflected after the summary statistics.
The distribution of the sections on the line. The throughput of each section can be calculated separately, and the values of various related indicators reflecting the operational status are calculated separately. For example, the number of passengers getting on and off at each station, the throughput of each section, the maximum section throughput during peak hours, and the full
The load rate, the passenger turnover of each line (person/km), the average distance, the passenger density, the imbalance factor, the number of IC cards and the number of ordinary votes, and their proportion.
2. The role of the passenger flow survey (people counter and passenger counter)
Citywide surveys can be conducted on all lines during the entire day of operation. It can be reflected in the same
The operation status of the city's public transportation system within the time, the city's large-scale distribution points and
The distribution of residential and industrial areas, the occupancy of IC card passengers in the city and
The distribution of IC card traffic on various regional lines, when organizing important information about public transportation plans and prospects.
(2) Visual inspection of passenger flow survey method (resident passenger flow survey method)
1. Visual survey of passenger flow survey (people counter and passenger counter)
This survey method is to set up investigators at the mid-point key stations (one station or multiple stations) or on the peak section with large passenger flow, within the specified time. Visually record the number of passengers getting on and off, the number of people in the train, the number of people staying in the station, and a cross-sectional survey method for passing the train.
Whether the change and the distribution are reasonable, the second line, the station, the timing, and the regular investigation. The survey data will be aggregated and ready for comparative analysis. Increase or decrease the line
With the car, adjust the capacity to provide a reliable basis. It is the most commonly used method for line operation management.
This passenger flow survey method is technically strong, and investigators should be familiar with the line.
In terms of road operation, it is necessary to grasp the number of seats of various models, the area that the passenger can stand and the rated vehicle capacity. And can accurately estimate the number of passengers. The accuracy of the measured data is generally required to be above 90%. The date of investigation and the specific time can be determined according to the general passenger flow dynamics and the specific conditions of the survey line. Whether the time is chosen properly or not directly affects whether the intended purpose of the investigation can be achieved.
Raw records measured at each point, grouped by 0.5 hours or 1 hour
Count the number of people getting on and off, passing the number of trains (capacity), the full load rate of vehicles and the number of people leaving the station. According to the statistical summary of passenger flow data, analyze the full load of the running vehicle. According to the passenger distribution volume at the survey point, the capacity of the survey time can be analyzed to adapt to the traffic volume, and the increase and increase of vehicles, vehicle reduction and improved dispatching methods can be adjusted to balance the capacity and traffic volume.
2. Visual inspection of passenger flow survey (people counter and passenger counter)
This survey method is simple and easy to use, uses less manpower, and is easy to organize and quick. It is convenient to organize local key areas, key lines, key sections, and key time surveys. The survey data is highly reliable and is an improved scheduling tool.
Apply, prepare or modify the basic information of the driving schedule. The dynamics reflected by the visual traffic survey method are partial and can be combined with other survey data to obtain better results.
(3) Inquiring passenger flow survey method (people counter and passenger counter face recognition instrument)
1. Generalization of the inquiry flow survey method
The Inquirer Flow Survey Method is a method of assigning investigators to record the location of each passenger's access by means of an inquiry. Can be divided into two types of on-board inquiry and station inquiry. On-board enquiries are generally used in lines with long distances and small numbers of vehicles getting on and off. In the urban lines with large passenger traffic, large station distance, and large number of vehicles getting on and off, the method of garrison inquiry is adopted. The number of people assigned to the inquiry investigator may be based on the number of passengers at each station.
The inquiry survey method can be carried out on all lines or along the way according to the size of the public transportation. Under the limited conditions of the investigators, they can be carried out in batches on a regular basis. The length of the investigation can be determined according to the purpose of the investigation.
2. Inquire about the role of passenger flow survey (people counter and passenger counter)
The inquiry survey can harden the location where each passenger gets on and off the bus. At the same time, it can also reflect the number of passengers who get on the train at each station, the distance from the passengers at each station, the passenger load on each section, and the full load rate. When the conditions permit, you can also ask the passengers to transfer, to grasp the passenger's riding rules and collection direction, to solve the problem of the high-section station of the line, and to facilitate the connection of the line layout.
(4) IC card passenger flow survey method (people counter and passenger counter face recognition instrument)
1. Summary of IC card passenger flow survey method (people counter and passenger counter face recognition instrument)
The segment card pricing information IC card card information reflects the road segment and start and end points and time of the passenger on the line. Through certain data mining and sorting, various forms of passenger flow data can be obtained for passenger flow analysis.
2. The role of IC card passenger flow survey
Can be used as a partial line full passenger flow method. A full-time survey of the dynamic characteristics and laws of passenger flow is achieved to obtain dynamic changes in passenger flow in the area and route. For example, the increase and decrease of the passenger flow at the main distribution points along the line and the distribution of the cross-section passenger flow at different times provide information for the preparation and improvement of the travel schedules of some routes in the area.
Third, passenger flow dynamics and its evolution law (people counter and passenger counter face recognition instrument)
(1) Passenger flow dynamics on the line network (people counter and passenger counter)
The passenger flow dynamics on the line network refers to the passenger flow dynamics on the citywide floor plan. It reflects the number of passenger traffic on the public transport routes in the city and its distribution characteristics: the traffic volume in the central area of the general city is always the most concentrated and dense; the marginal areas are relatively sparse.
The passenger flow dynamics on the line network generally extend gradually from the collection and distribution points in the central area. The dynamic distribution of passenger flow has a great relationship with the overall layout of the city and is subject to the road pattern. Reflected on the line network, there are generally four types: radial, radial, checkerboard, amorphous,
The online traffic dynamic value of the line is expressed by the throughput. The throughput of each road segment is arranged in a series of chronological order, which can display the dynamic value and change characteristics of the passenger flow on the line.
According to the direction and value of the dynamic changes of passenger traffic on the line and the fluctuations
The extent is to study the new ways of the route, adjust the selection and equipment of the operating vehicles, and modify the travel schedule and other information.
(2) Passenger flow dynamics in the direction (people counter and passenger counter)
Every line of public transportation has both directions of up and down. The traffic in both directions is not equal in the same time group. In some lines, the two-way traffic is almost equal, and some lines are very different. Due to the different passenger flow dynamics in the direction, two values can be calculated, and the dynamic types can be divided into two types: one is a two-way type, and the other is a one-way type.
1. Two-way type, the two-way traffic value is close to the same, urban line
More than two-way type. This type of line is easier to arrange in the vehicle, and the utilization rate of each vehicle is higher.
2. One-way type The two-way traffic values vary greatly, especially
Many routes to suburban or industrial areas are unidirectional. Such lines are more complicated in vehicle scheduling, and the effective utilization efficiency of each vehicle is lower than that of the two-way type.
The passenger flow dynamics in the research direction can provide a basis for determining the corresponding dispatching measures and reasonably organizing the vehicle operation.
